Check light is on
Scanned the PCM; If the check-engine light comes on, here are some tips on what you should do:
Look for a serious problem that requires immediate attention. Check
your dashboard gauges and lights for indications of low oil pressure or
overheating. These conditions mean you should pull over and shut off the
engine as soon as you can find a safe place to do so. On some cars, a
yellow "check engine" means investigate the problem, while a red "check
engine" means stop right now.
- Try tightening your gas cap. This
often solves the problem. Keep in mind that it may take several trips
before the light resets. Some vehicles have a separate indicator that
warns of a loose gas cap before the condition sets off the "check
- Reduce speed and load. If the "check engine" light
is blinking or you notice any serious performance problems, such as a
loss of power, reduce your speed and try to reduce the load on the
engine. For example, it would be a good idea to stop towing a trailer.
Have the car checked as soon as possible to prevent expensive damage.
Contact OnStar, if available. If you have a 1997 or later General
Motors vehicle equipped with OnStar and an active OnStar subscription,
contact an advisor who can read the trouble code remotely and advise you
about what to do.
- Have the code read and the problem fixed. If you
want to diagnose the malfunction yourself, you can buy a scan tool at
most auto parts stores. Prices range from about $40 to several hundred,
depending on the model and the features. The tools come with
instructions on how to hook them up and decipher the codes. But unless
you have a good knowledge of automotive diagnostics, you're probably
better off taking the vehicle to a professional. Some automotive parts
stores will read and interpret the code for you without charge. Unless
there is an easy fix, they may simply refer you to a mechanic.
Don't go for a state emissions test. In a late-model car, an illuminated
"check engine" light probably is a sure sign your car will fail the
test. In some states, it's an automatic failure, even if the problem was
nothing more than a loose gas cap. By the way, don't bother trying to
fool the inspection station by disconnecting the battery or using any
other method to erase the trouble code and turn off the "check engine"
light. Your vehicle's computer will let the inspection station know that
its codes have been erased, and you'll just have to go back again.
Hope this helps; also keep in mind that your feedback
