Check Engine Light

RE: Check Engine Light
What year is the car? I have a 93 and went to autozone and they couldn't troubleshoot the light cause they didn't have the scanner LOL. Did it myself with an Ohm meter. But mostly what sets the light off is a problem in a sensor somewhere that is out of specs. If the sensor fails the ECU will go into an Open mode and allows the car to run. You will not get the best preformance till the sensor is fixed.

01 Eclipse GT, I'll probably just take it somewhere and see if they can diagnose it. It would be nice if I could do it with ignition though!

yeah, I was told in one of the other threads about the key dance trick. I tried it yesterday in my 97 RS and it didn't work... Maybe I'm doing something wrong. Can someone explain this trick further or point me in the right direction to read about it? 'Tank ya.
Why would a bad sensor give your car worse performance?

Example, your O2 is out of voltage specs and can not tell the ECU how much O2 is passing thru your exhaust. So the ECU takes the safe approach and richens the mixture goint into the Cylinder to make sure the engine doesn't get a lean condition (BAD). More fuel is use so you lose preformance in the car though, you might not tell if you are only driving around town. Your gas milage would go down though. 01's can be checked at Autozone though and I would start with them. At least it would give you a starting point to troubleshoot. GL with it

Took it to Autozone but they didn't have the correct harness to plug into the car, so I took it to Advanced Auto and encountered the same situation. So I took it to the local garage, they CAN do it but will charge me $20. Why can't I get it done for free when everyone else can?
