2006 Chevrolet Cobalt Q&A
2006 Chevrolet Cobalt Question: Intermittent Check engine light
Once the light has come on, the code will be stored until someone erases the it, so when you take it in, have them give you a printout of the stored code information. Post the code here and someone may have some info for you. - Bret Bodas
I am having the same problem. I took to AAMCO and they replaced my plugs and spark plug wires along with the boots. It came back on. The diagonosies was a fuel injection misfire. Had those cleaned and today it is back in the shop. They are now saying need a new oxygen sensor? I am so tired of this entire thing. They have reset the light 3 times and after a day it is BACK!! - Visitor
I have a 2007 Chevy Cobalt and my check engine light is on and the code is P0496, can someone tell me what this might be and if so where can I find it to replace it?
