The Byte Stuff (Your Vehicle's Computers)

Nobody has to tell you that computers are a part of so many things in our lives.  Smartphones, kitchen appliances, vacuum cleaners, televisions.  You name it—it has a computer in it.  And your vehicle is no exception.

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; air bags, 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.

Gas Smell! (What Causes Gasoline Odors)

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents. 

There are many things that can cause a vehicle to give off a gasoline odor.  One of the easiest to track down is the gas cap.  It could be missing or it doesn't seal well any more (they do wear out).  That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis.

Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal).  They can leak gasoline, too.

It's always a good idea to check the garage floor for any gasoline puddles.  Note the location of the puddle in relation to the vehicle. If it's near the back, that's possibly the fuel filler neck or the gas tank leaking.  In the middle of the vehicle? May be fuel lines.  Near the front? Could be fuel injectors (or carburetor if you have one) or fuel pump. 

There are other causes of gas odors, and you need an expert to figure out the source soon.  Gasoline leaks are nothing to play around with.  Gasoline is flammable, potentially explosive and its fumes can damage your lungs. A trained technician can pinpoint the cause and get your garage back to smelling like a normal garage again.
