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 Illinois 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.

Hello Urbana . Have you ever had your Check Engine light come on? Did you panic? Or just scowl and ignore it? What should you do? Pull to the side of the road and call a tow truck? Or just keep driving? What does that little light really mean for Urbana drivers?

First of all, the Check Engine or Service Engine light does indicate that something is wrong. That's why it is called a warning light. But the something that is wrong might be a loose gas cap, or it might be serious vehicle engine trouble. That's why Urbana residents often don't know how to respond to it.

The Check Engine light has two modes: it flashes or it stays on. A flashing light is serious. You need to get your vehicle to PDR in Urbana ASAP. No, you don't need to call a tow truck, but, yes, you can't wait to get your car serviced. If your Check Engine light is on and flashing, you should not tow trailers, haul heavy loads or drive at Illinois freeway speeds. Any of these could lead to serious damage that could result in repair bills for Urbana drivers who ignore it.

A steady Check Engine light is less serious, but that doesn't mean it can be ignored. You should plan to get your vehicle inspected at your local Urbana automotive service center at the first realistic opportunity. Not the first convenient opportunity, but the first realistic one.

Modern automobiles have a computer in the engine that monitors and controls many of the engine functions. When the computer senses something wrong, it first tries to fix the problem itself by adjusting the vehicle engine. If the problem persists, the computer signals the Check Engine light to come on.

This process stores a trouble code inside the vehicle engine's computer. Your service advisor at PDR scans the computer and reads the code. This does not tell the technician exactly what is wrong with the car, but it gives him a good idea as to where to start looking.

Of course, the best thing to do is to keep that pesky Check Engine light from coming on in the first place. Good vehicle care and routine preventive maintenance go a long way to keeping your vehicle out of your Urbana auto repair shop. But, if that light does come on, be smart. Take care of the problem early, and take care of it professionally.

The check engine light might come on in your vehicle. It’s an amber colored light that shows on your dashboard.  In newer vehicles it might just be a problem with your gas cap not being screwed on tight enough (or a worn gas cap), causing the vehicle to fail the self-diagnostic evaporative emission test.  All you need to do is go to your gas cap and verify that it is tight. If that was the problem, the light will turn off and everything will be fine within one or two days.

Resist the temptation to have someone “clear” the codes to turn off your check engine light.  This erases important diagnostic information that your technician needs to diagnose the underlying problem for the check engine light – and any other pending problems that may be stored in the computer.

If the problem is still there - you still see the light - bring your vehicle in and have it checked out as soon as possible.

When your Check Engine light comes on, you may be torn between utter panic and just wanting to ignore it and hope it goes away. That's perfectly understandable. That same Check Engine light could come on for anything from a serious engine or transmission problem all the way down to a loose gas cap.

There's a very common misconception that the trouble codes stored in your engine computer when your check engine light comes on will specifically identify a problem. It's really more like pointing to the symptoms of a problem.

Call PDR at 217-367-9481 for help with your Check Engine light.

Think of taking your temperature. Say it's 101°. Your heat sensor – the thermometer – tells you that your temperature is out of the normal range. But it doesn't tell you why you have a fever. Is it the flu or a sinus infection? You need more information, more tests.

For any given trouble code, there could be a number of causes. So your trained technician takes the trouble code as a starting point and begins a diagnostic process to determine the cause of the problem. And some problems take longer to solve than others.

When your engine management system logs a problem and illuminates the check engine light, your Urbana service technician at PDR will plug in a scanner, download the trouble codes and go to work tracing the cause of the problem.

That's just the first step. That's when our PDR technician's training, equipment, databases and skill get put to work diagnosing the problem and fixing it.

If your check engine light is flashing, it means that the problem could lead to serious damage. You should get to PDR as soon as possible to get the problem solved. If it's on but not flashing, you have some time to get in at your convenience.
