Cayenne here and you probably never thought about it, but your vehicle is like a rolling weather station.  It can check the outside temperature, let you know when the roads are slippery and help you deal with rain. And how it does all those things is pretty cool.  So today, we will bark about your vehicle sensors and how they adjust to those weather road conditions.......let's get barkin'

First, just like any weather station, a vehicle has sensors that measure the driving and weather conditions you find yourself in.  Some of those sensors can control computerized systems in your vehicle to react to the weather.  It depends on whether you have a 2-wheel, 4-wheel or all-wheel drive vehicle and how those sensors will respond.

Let's start with temperature.  Most vehicles now have a thermometer that measures the temperature outside.  It's usually in the front, and likely will tell you on the instrument panel what the outside temperature measures.  But a temperature sensor will also tell your vehicle's computers to turn on or off certain systems like the heating or air conditioning.  If your ambient temperature sensor isn't working right, some symptoms are a malfunctioning automatic A/C or a temperature display that is way different than the app on your phone says it should be.

Your vehicle will also have sensors that measure your speed at each wheel.  They work with an onboard computer to measure slippage in any of the wheels so traction control and antilock brakes work correctly in case of slick roads.

Your vehicle can measure something called longitudinal and latitudinal acceleration, and it uses a yaw sensor to do it.  That helps it determine if you might be in an oversteering or understeering situation.  It's important because it works with your vehicle's brakes to apply stopping power to keep you in control.

A steering wheel sensor tells the vehicle's computers what the driver is doing with the wheel.  It also can work with those wheel sensors to measure how slippery the roads are, whether it be due to a wet (rain) or granular (gravel or sand) surface.  By sending different torque or braking to each wheel, it helps the driver maintain control.

More and more vehicles now have a rain sensor that can turn on the wipers automatically when they measure precipitation on the windshield.

So, you're driving your own weather station and making sure all this data is coming in properly depends on how each component is working.  Regular service and maintenance on these systems are important to ensure they can do their job. Your rolling weather station can't predict the weather, but it can sure help you deal with it, so help it do its job right.

Here is my quote for the week in regards to the weather.

Don't knock the weather; nine-tenths of the people couldn't start a conversation if it didn't change once in a while. ~Frank M. Hubbard

Hey, it's the Duke and I just got back from nice run, breathing in the fresh, clean air.  But have you ever gotten in your vehicle and said what is that awful smell?  Don't blame it on the dog.  It is probably your vehicle with that rotten egg smell.  So today we will crack the mystery out of that foul smell (no yolk intended).

The pungent smell of rotten eggs can send people running for the hills.  So when that odor is inside your vehicle, yikes!  Yolks!  The good news is that a trained service technician can search the source of that smell and stanch the stench… that comes from another word that begins with S. - Sulfur.

Fuel contains small amounts of hydrogen sulfide, but they're enough to stink up a vehicle when it's not properly burned.  You may know that the smell of rotten eggs can often be a sign of a catalytic converter that isn't working the way it should.  That could be due to age, damage or an abundance of oil that's clogging it up. 

If a sensor in charge of managing the fuel has failed, the engine can run with too rich of a fuel mixture.  That can overload the catalytic converter and allow some of the byproducts to escape without interruption from the chemical reaction that is supposed to prevent them from going out the tailpipe.

There's another possibility, but it's usually only in stick-shift vehicles.  That's leaking old transmission fluid.

Catalytic converter repairs are best left to a professional. Technicians at your vehicle service facility have equipment and training that can help them pinpoint the cause of this funky fragrance.  Once the cause is found, repairs made and/or parts replaced, the smell should go away fairly rapidly.

I leave you with my rotten egg joke of the week,

Why can't a rotten egg become a comedian?

He only has bad yolks

Good day to all, this is Cayenne here and in a year marked by unusually heavy flooding in North America, drivers are very aware of the possibility they may find themselves driving where water has come over the road.  It can be a daunting and frightening situation.  Flooding waters can move quickly and unpredictably, so you have to keep your wits about you when you encounter that situation.  So today we will flow into what to do driving through standing water.  Let's get barkin'!

Here is a sample of one vehicle manufacturer's guidelines on what to do.  First, the vehicle is designed to go through some water, but you must be careful.  Never attempt to drive through water deeper than the bottom of your tires.

You can get out of your vehicle to check the depth of the water, but you can never be sure that you aren't going to drive into a spot where the road has washed away.  You can't see below the surface of the water, and suddenly you could find yourself in a place where the road drops off unexpectedly.  In swift-moving storm runoff, your vehicle could literally be floating away with the current, putting your life and those of your passengers in mortal danger. 

Never go more than 5mph/8 km/hr when you drive through standing water.  That minimizes the waves you create.  If you DO find yourself in water that is touching your drivetrain components, that water can damage them.  And if you get water in your engine, it can lock up in seconds and stall.  The potential damage can be catastrophic.

You may have found yourself driving in water deep enough to reach your drivetrain components, and it's essential that you have a technician check the fluids to make sure they haven't been contaminated.  That includes engine oil, transmission and axle.  Driving with fluids contaminated with water can severely damage those components. 

The bottom line is to avoid driving through water at all if you possibly can.  Check your vehicle's owner's manual to see if there are specific guidelines for driving YOUR vehicle in standing water.  It's information that could save your life.

I leave you with my water joke of the week.  

"There are two reasons why you should never drink toilet water.

Number one. And number two."

HAPPY HOLIDAYS, Duke here and with all the traveling you will be doing over the holidays, sometimes we want to be the DIY for our vehicles.  This can be tricky especially with all the computers and technology.  So today we will bark about the perils of trying to DIY on vehicle repair.  

Your vehicle is a complicated machine, and yes, it would be nice if you could take care of all of its problems yourself.  There was a time when vehicles were simpler and it wasn't too hard for a weekend mechanic to replace brakes, adjust a carburetor, or perform a tune-up.  But vehicles are far more complicated these days, with traction and stability control, anti-lock brakes, airbags and fuel injection just a small sample of the new technologies. 

Like a lot of things these days, technology changes in leaps and bounds.  Anyone who repairs vehicles has to stay up on the latest computers, sensors, suspensions, steering, electronics, hydraulics and more.  Many power steering, braking and heating and air conditioning systems that used to be mechanical are now being replaced by electronic systems.  Computers are an integral part of much of the latest automotive technology, something you didn't see a lot of until as recently as the 1990s.

Today's most highly-trained technicians are able to keep up with how to perform the latest repairs and services by continuing education about their craft.  When once an auto repairman could do fine with a lift and a good set of tools, now specialized electronic analysis equipment and tools are must-haves when it comes to vehicle repair.

Because of how fast technology changes, access to the latest repair databases and manuals is also important.  Manufacturers require certain service procedures to be performed precisely, and any other way can leave a vehicle compromised when it comes to performance and safety. 

Your vehicle is capable of traveling at high speeds on challenging surfaces with ever-increasing traffic issues and unpredictable obstacles.  You need your vehicle to be working up to its engineered potential.  That's why you should leave repairs and services to professionals.  They work on vehicles every day, and years of experience with hundreds of repairs equip them to deal with the unexpected as well as the routine. 

When you develop a trusting relationship with a reputable service facility, you can have confidence that the maintenance, service and repairs are being done by people who know what they're doing.  Your safety and your vehicle's performance and reliability are well worth it.

Safe travels and Merry Christmas

Hey Duke here and there are some dashboard lights you should pay more attention to than others.  One is the airbag light.  If it's on and your vehicle is in an accident, your airbags probably won't do their job.  So today we will bark about the importance of the AIRBAG Light, it will save your life.  So let's get barkin" on this important subject!

Automakers began installing airbags in the late 1990s since they were mandatory in the United States, and manufacturers have included them in Canadian vehicles as well.  Safety experts say using a seat belt with an airbag gives passengers the best chance of surviving a crash and minimizing serious injury.

The airbag warning light takes a few different forms.  Some look like a picture of a belted passenger with an inflated airbag from a side view.  Or there may be a warning light that says something like "Air Bag," "SRS" (for supplemental restraint system), "Airbag Deactivated" or "Air Bag Off."

Different things cause the airbag light to come on.  Your vehicle may have been in an accident during which, while the airbags didn't inflate, crash sensors were activated.  Some of them may be connected to your vehicle's seat belts.  A technician can reset the airbag if this has happened.

Fuses can also blow, which will cause the airbag light to come on.  Another possible cause? A sensor that tells the vehicle's computer whether or not there is someone riding in the passenger front seat may be malfunctioning. 

Airbags are not for the do-it-yourselfer.  They are sophisticated systems that require specialized training and equipment to diagnose and repair.  If an airbag light is on, take it to a qualified service repair facility.  One more thing: remember that safety experts have designed airbags to work in conjunction with seat belts for maximum protection in accidents.  So always wear your seat belt.  

.....and remember, Safety never takes a day off

Hey Duke here, and you know I love the grinding sound when I enjoy one of the Wagu Rib Eye steak bones I get once in a while, what a beautiful sound and tastes good too.  But what if your vehicle makes a grinding sound when you turn the steering wheel, it's speaking to you and that is not a good sound.   So listen to what it's saying and you could avoid a much more costly repair down the road.  So let's grind our way into this important noisy subject and get barkin'!

A grinding sound coming from the front of your vehicle when you are turning can offer some very informative clues as to what's going on.  One cause could be that there's a problem with the mechanical linkage that enables you to turn the wheels.  Another is that the hydraulic system that makes turning the steering wheel easier may have its own problems. 

Think of it.  Hydraulic power steering has many components that need to work in tandem.  The power steering fluid may be too old and contaminated.  Or its level may be low. That may be caused by a leak somewhere in the system. A technician can check things over to find out exactly what's happening.

Other causes of grinding while turning can be problems with the suspension in the front.  You may have a failing CV (constant velocity) joint.  It could be your brakes are partially engaging while you are turning.  That metal-on-metal sound is never a sign that things are working just the way they're supposed to.

To a technician looking to pinpoint the problem with your vehicle, it's not a daily grind at all.  Experience and training will help her or him zero in on what's causing the noise and get you back on the road. Maybe you can enjoy your sound system more after that distracting background noise has disappeared!

And me, well I go back to enjoying my Wagu Ribeye bone and the lovely sound it makes

Duke here and did you decide this year it was time for a new car and finding out that inventory is still low at the dealer?  Well, used cars have been a hot item these past 2 years and the price on them is close to that of a new car.   So today I am here to bark to you about what to do before closing the deal on the used car.  Get a Used Car Inspection! I cannot bark enough about this and how important it is to have a neutral party take a look at that used car and make sure it is worth the money you are paying for it.  So let's get barkin' on this hot topic today?

Let's face it.  New vehicles are expensive, so finding a good used one can save drivers a lot of money.  It's tempting to look through ads, find a private seller who has what you're looking for, and pay a price you think is a great deal.  But when you go over to look at a used car, do you really know what to look for to uncover potential problems with it?

The answer is probably no.  Used cars can look great on the outside, maybe even have lustrous paint and a super clean interior. But is it possible that the vehicle's been in an accident? Does it have electrical problems you can't detect easily? Is any fluid leaking that you don't know about?

Think about it.  You are about to spend thousands of dollars on a complex machine and you're considering judging its condition without much expertise.  That's why it makes sense to have a qualified technician inspect any used vehicle you're considering buying.

Many vehicle repair facilities will do it for around $100-$200.  They'll check to see what's working right and what's not working.  They'll check for leaks and how strong the battery is; they'll look for signs it's been in an accident or has been painted. They'll look in places you'd find inaccessible, and they'll take it for a test drive to see what noises, vibrations, and smells might give clues to any major problems.  An inspection usually takes about an hour.

You should have an inspection done by a technician you know and trust.  They'll have your best interests in mind.  And the inspection should be done before you start negotiating a price with the seller.  It's money well spent to either give you peace of mind that you're getting a good vehicle or steer you away from a lemon. 

One sign a used vehicle isn't a good deal? If the buyer refuses to let you have it inspected.  That says just about everything that needs to be said.    

Allied Auto Works can inspect that used car for you to make sure you are getting one fine vehicle to drive down the road.  Give them a call today and tell them The Duke sent ya!

Hey, Cayenne here and have you ever felt silly pulling up to the gas pump and realizing when you got out the gas tank was on the other side of the car.  Well today we will bark about the Fuel Filler location.  I'm not fueling you. 

If you've ever gotten in an unfamiliar vehicle, maybe a rental car, you may have pulled up to the gas pump and wondered, "Which side is the fuel filler on?" Here's a tip for you.  There is usually a little arrow on the instrument panel near the fuel gauge that points to the side where the fuel filler is. 

But why are the fuel fillers not all on the same side, anyway? There are lots of reasons.  At one time, many manufacturers tried putting them in an easy-to-reach spot: in the center of the vehicle's rear end.  Some even hid them behind a hinged license plate door.  Cool place, but it turned out not to be a good idea.  When a vehicle with a fuel filler in the rear was hit by another vehicle from behind, it was much more prone to catch fire and explode.

Safety regulations now dictate that the fuel filler doors be placed within crumple zones and away from where they can drip fuel on hot exhaust pipes or near electrical connections.  But why do manufacturers put them on either side?

Some say it should be on the side away from the road.  That way if you run out of gas and have to add a little from a gas can as your standing at the side of the road, you'll be a little farther away from passing traffic.  So some companies from North America and many European firms with left-hand drive put their fillers on the right side.

Some manufacturers think convenience for the driver is paramount, so they put their fuel fillers on the driver's side.  If you have a vehicle with a cable release for the fuel door inside the cabin, it's usually on the same side as the steering wheel.  As you can see, there's no standardization.

Fuel doors need regular maintenance such as lubrication, and your gas cap (if your vehicle has one) should seal properly.  Have your service facility inspect those regularly. Wherever your fuel filler is, it's obviously important that you can get at it easily because you have to fuel up sometime. Otherwise, you're not going to go too far!

Well hello, it's Cayenne, did you know Coonhound breeds are known for being intelligent (yes we have common sense) and loving, known for their inquisitive charm, and can be quite goofy. They are scent hounds and are most noticeable by their long ears and large bays.   This is me except I am not goofy, I let Duke be the goofy one.  Well, today we will bark about the Not-So-Common Sense on our vehicles - sensor failures.

So your vehicle won't start.  What's the first thing that comes to mind?  Battery dead? Starter motor worn out? Out of gas?  Well, those are all reasons that make sense.  But your vehicle may be refusing to start because one of its computers is being warned that to do so might damage it.  Here's how that works.

You have lots of computers in your vehicle.  They need to know the status of things so there are several sensors monitoring various things going on.  These sensors send information to the computers that adjust the fuel and air mixture so you don't waste fuel.  They know when things aren't quite right and prevent you from starting your engine if that's going to damage it. 

Other sensors make sure the coolant is at the right temperature, check to see you are not polluting the air, and make sure other electronic components are performing their tasks correctly.

Here's an example of a sensor doing its job.  Your engine needs oil to lubricate metal components so the friction doesn't damage them.  Your engine has an oil pressure sensor that tells a computer called the Electronic Control Unit (ECU) if things are good to go or if there's something wrong, maybe the oil pressure is too low to keep things lubricated.  If it is, it gives a signal for the vehicle not to start, protecting the engine. 

Of course, the sensors can go bad, too, with some of the same results.  And so someone has to figure out if it's the sensor that's failed or if it really has detected a problem.  That is a challenge for technicians with specialized equipment to decipher the signs.  If a bad sensor is found, it may need to be replaced.  Sometimes a thorough cleaning can do the trick.  In either case, your service facility can track down the problem and get you back on the road.  Makes sense, doesn't it?

Call Allied Auto Works today, it makes common sense, and tell them that beautiful, hight intelligent Coonhound sent you,

Duke here and I love to take a good bite out of juicy steak, whoops that's the wrong byte.  Bytes we're talking dog trackers, Alexa, smartphones, kitchen appliances, vacuum cleaners, and televisions.  You name it—it has a computer in it.  And your vehicle is no exception.  Nobody has to tell you that computers are a part of so many things in our lives.  So you guessed it, we will take a bite out of bytes and look at our vehicle's computers.  

The earliest cars relied on the technology of their time, and there was no such thing as a computer.  But now, it's not unusual for a vehicle to have as many as 150 computers in it. They perform a variety of functions. An important one is diagnosing your vehicle's problems.  There are various sensors throughout modern vehicles that measure thousands of data points.  When something is not working correctly, they send a signal to another computer that stores that information. The data can be read by someone who has a special computer that plugs into a port in your car.  It displays certain codes that help technicians track down the culprit. 

But it's not just the diagnostics that are computerized.  Everything from your vehicle's fuel injection to anti-lock brakes is.  Convenience features such as power windows, rain-sensing windshield wipers, a wi-fi-hot spot, streaming video and navigation are all sophisticated computers.  Then there are the safety features; airbags, traction control, automatic emergency braking and a host of others are all dependent on computers.

It is important that those computers work correctly because they interface with many of the other computers on board.  To properly diagnose problems with those computers requires training and special equipment. Your service facility has invested considerable resources into both, and they are equipped to properly evaluate and repair and/or replace malfunctioning components. 

Some lament the days when backyard mechanics could pull out their tools and do their own repairs.  Those days are fast disappearing with the computerization of vehicles.  But look at the bright side.  Your vehicle does so much more, has so many more features and travels far more safely than those past generations drove.  And they're bound to get better and more sophisticated down the road.
