The light comes on for 4 reasons.
1: SMOG. failing.
2: horrible MPG. (engine is running in limphome mode....... fix it.
3: pending doom. (early warning)
4: the NAG lamp , the old leaded gas, mileage nag light (USE FED only model)
there is no need for any reader ( they dont sell them for trackers, and sidekicks)

all there is , is the paper clip test. the winky-blinky test.

Check engine light


Need to know what the code is. If you don't know how to retrieve it you can take it to an autoparts store and they will usually scan your cars computer with a code reader and give you a code. This will give you an idea of what the problem may be.

You will need to have it plugged into a scanner or at least a code reader to find out what code or codes it has and then go form there.

Major auto parts stores have code readers and will read out your codes for free. The engine light indicates that at least one code is waiting to be read.

My 1999 Chevy Prizm has the check engine light on - although I have had no mechanical problems with the care, it drives fine. I have lubed it, and gotten gas recently, but light still stays on.


Your check engine light is an emissions warning. Your vehicle will not pass smog with the engine light on. You can go to kragen or other auto parts stores and buy a GM code reader for it. Though it runs fine, its telling you that a sensor or something is bad.

The car ( 2003 Escalade)runs fine but check engine light came on.


Hooking a code reader onto the OBD II port will give you a code so that you can figure out what is wrong with it. It is most likely an emission code which won't hurt the performance but possibly the gas mileage

2000 vw check engine light on, oil fine


Ignor it, or if it really annoys you disconnect the battery for a few minutes and it will reset. My 2001 check engine light is on every time it rains(often) many times it resets on it's own within a few days. My guy is a mechanic and it runs fine, so its usually just a cranky bug. Or you can buy a code reader at pep boys or an auto store and it will tell you the codes associated with the light.

It dies when put in gear


have someone check it with a code reader to determine reason for the check engine light. it could be the source of your problems. the check engine light comes on so you know there is a problem. with most vehicles becoming more complex, the code reader can be used to pinpoint many problems that are not detected otherwise.
