The Light Many Drivers Fear (Check Engine Light)

Ask just about any driver about one thing they fear seeing inside their vehicle and they'll say it's the Check Engine light coming on. You know, that little light on your instrument panel that is in the shape of a vehicle engine, often accompanied by the words Check, Check Engine, Check Engine Service, or Service Engine Soon.

There are so many different reasons that light shows up, from something as simple as a loose gas cap to a more serious problem that requires immediate attention. 

The Check Engine light comes on because a component of your vehicle's onboard diagnostics system is telling you something isn't operating normally. Your vehicle has a lot of sensors built in, all tied together by computers.  When the sensors are showing that things somewhere aren't functioning the way they should be, they alert the vehicle's diagnostic computers and tell you something's amiss.

The simple rule is if the Check Engine light is on steadily, it's something you should have checked soon but it's not urgent.  If it's flashing or has turned red or orange instead of yellow, get your vehicle checked out as soon as possible.  If you don't, you may be facing some costly repairs.

Here are a few problem areas that may trigger your Check Engine Light. 

  • Something's wrong with the emissions equipment.  Maybe too much fuel is getting into the catalytic converter, or the exhaust gas recirculation system isn't working right.  Because some of these components are expensive to replace, it's worthwhile to have a technician look at your vehicle sooner rather than later.
  • Your ignition system isn't working right.  That means spark plugs, coils, and wires.  If your engine is misfiring, that could translate into an illuminated Check Engine light.
  • The transmission isn't behaving the way it should.  The transmission works in tandem with the engine, so if a sensor sees something wrong there, it will tell the vehicle to turn on the Check Engine light.

As you can see, there are many things that can cause the light to come on, and when it does, it really is a good idea to find out why.  When you bring your vehicle in, we have an electronic device that can read a code or multiple codes stored in your vehicle's computers.  That will provide the technician with clues pointing to the cause of the trouble and helps pinpoint where that trouble is.

Beginning to See the Light (Check Engine Light Diagnostics)

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine.

The truth is that Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair it is designed to alert you to, to tell you something's not quite right.

Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light.

If it's flashing, that could be serious. Look at some of the other warning lights or gauges such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard.

Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible.

If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service.  The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later.

When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored.  It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely.

Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light."

The Light Nobody Wants to See (Check Engine Light)

You've probably had your Check Engine Light go on.  Then it goes off and you figure, hey, whatever the problem was, it's gone now and I don't have to worry about it.  Well, the problem may have gone away and it may not have.

Your vehicle likely has one of these warning lights on the instrument panel: an amber light that looks like an engine or reads "Check Engine" or "Service Vehicle Soon."  If that light comes on and stays on, it usually means there's something amiss but not urgently in need of service.  (Now if it's blinking, that's another story that we'll deal with in a minute.)

Sometimes when it comes on and stays steadily lit, the problem will go away and the light will go out.  Sometimes it will stay on until you get the problem fixed.  Either way, the engine's computer will store a code that can provide clues to what's not working—or wasn't working—the way it's supposed to.

If you are just dying to know what that code is, you can buy a little code reader or take your vehicle to an auto parts store and they'll read it.  Problem is, the code offers so many options that unless you are a trained technician, you probably won't have a clue what those codes mean. 

So if you want to be sure, take it to your vehicle repair facility and have them check it.  Technicians are trained to decipher the codes and, using their experience and other diagnostic equipment, can get to the root of the problem and fix it. 

As we mentioned before, if that Check Engine light comes on and is blinking, it means a more serious engine malfunction that can damage expensive components such as the catalytic converter and even the engine itself.  It's important to have that checked by a professional as soon as possible.

Things Aren't Always What They Seem

If you drive, you know at some point, something's going to go wrong with your vehicle.  And sometimes, it's pretty easy to figure out what's wrong, like a flat tire.  But sometimes your vehicle's symptoms can be really puzzling.

One driver in IN was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual.

He was trying to figure it out, but none of it made any sense.  His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator.

It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems.  You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree.  That caused a tiny crack in his rear stoplight. 

That crack had gone unnoticed until that July day.  Turns out a summer rain allowed water to seep into the taillight casing, so this time when he drove to work, there was enough moisture inside it to cause his stop light to stick on.

When the stop light is on, the car's computer is programmed to act as if the driver is pressing the brakes. It also disables the cruise, accelerator and cruise control when the brakes are on, producing all of the symptoms.  Replacing the stop lamp switch fixed everything.

So, while some things that go wrong with your vehicle are pretty obvious, many seemingly defy all logic. That's when a trained technician can scope things out, replace the right part and get you going again.
