2006 Chevy Aveo Check Engine Light coming on and off
The engine light came on and stayed on. I replaced the gas cap and it went off about a week later. Stayed off for a few days, and then came back on again and is still on. Manual says it could be emissions. I've kept the car in great shape and changed oil/filter every 3,000 miles. I'm kind of surprised I'm getting this warning light. Any ideas or suggestions?

Re: 2006 Chevy Aveo Check Engine Light coming on and off
It needs a code scanner hooked up to it,to tell you why the light is on and the cause. If there is an autozone near you take it there or
call different auto part stores to find out if they do that.Without getting the code, it's just guessing what the problem is.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Tighten your fuel cap 3 times to make sure its tightned. don't push it in when you tighten it. Use Fuel injection cleaner like once a month... You may have gotten bad gas. Don't use 100 percet gas. Use gas with ethenol... you get better gas mileage. I go through 3-4 tanks a week. I use the 87 octane and I put Berrymans Fuel injection cleaner in once a week. I don't know about your hesitations though I drive a 5 speed
Many things can cause this problem...unfortunately the only proven way to remidy this situation is to have your car scanned by a reputable mechanic with a diagonstic machine $40-$80. This will tell what exactly is causing the check engine light to come on, in the long run its much cheaper replacing whats wrong than trying to replace things that arnt wrong.
This happened to me as well, just a few weeks after buying our 1999 ES300. Took it into Lexus for regular maintenance and to check this out. Apparently, if you don't replace the gas cap correctly and tight enough this can cause the 'trac off' light to come one. It will go off a little while after the cap has been replaced correctly. This also happened with my 2006 Murano, 'check engine soon' message.
I had a problem with my 2004 Chevy Cavalier doing this - Try taking it to Autozone for a free diagnostics. I did this and replced the gas cap. The seal was bad and when I replaced the cap, the check engine light went out after a little bit.
I doubt the gas cap is related to the light, though hopefully you can get a replacement for it because it can be dangerous. As for the check engine light I'm not sure what it could be. Is the car running making noises, does it stall?? If there are no obvious symptoms, you might need to take it to a mechanic so they can read the error message from the cars computer and determine where th eproblem is.
