My car engine light is on and we cant pass inspection. We took it to get the computer checked and the guy said it was a faulty computer. We investigated further and found out that The Chev Aveo has this problem a lot. Is there anyway to fix the problem without spending a **** load of money

emission light blinking ? engine symbol ? or check engine ? To fix it have DTC'S - diagnostic trouble codes checked . A flashing check engine means there is a catalytic converter damaging advent happening . Your best bet is take it an have it checked .

Have you disconnected battery at least fifteen minutes?

I have invested almost $1,320's from going back and forth with my mechanic, to fix the SRS light. Upon doing that he found other reasons has to why the light is not going off. him fixing everthing else is what made the totally price so high. Right after I picked it up from him took it straight to do emission but it fialed due to the computer readiness and was not picking up anything. The Emissions guy said maybe its cuz I just got it back, that the codes need to reclear. Had it back for almost 3 weeks now, the check engine light is back on. So went out and got a scanner so i can clear the check engine light. did that today took it back to same emmision place and the guy tells me the computer is still not picking the codes up. That Volvos have a wierd way to reset computer, Plz help me Asap already got pulled over twice, got lucky both times no ticket but dont want a third. Has my wife uses it to go to work so we should already have cleared the system by now

It will not pass inspection.

This light could be on for many reasons, this light comes on when the computer sees the engine is not running right or sensor reading is out of specs, you will need to have the computer scanned for codes, these codes will tell you in which system the problem is in, sometimes it can tell you very close to what the problem is, a loose gas cap can make this light light up or a faulty sensor or bad sparkplug and on and on, so start with the scan, autozone the auto parts store and others will scan the computer and give you a print out of the codes, for example a po301 code, if you get the codes i can help you find the problem, hope this helps.

either reset the computer or get a diagnostic scan to find the problem. the check engine light on doesn't mean it won't pass inspection

If your engine light is coming on, then there is a code somewhere in the computer,it may be a pending code.Its possible your computer is bad. Have your computer tested.

might be the map sensor, throttle position, or the computer is going bad!

you will need to drive about 50 miles till the computer checks the system since it was reset. Your check engine light may come back again, if it does run a vacum test..
