I have a check engine light that illuminated on my 2005 Pontiac wave. I brought the car in to a local auto repair garage, and thought the problem had been addressed as they diagnosed my car and addressed the codes that appeared. They replaced my oxygen sensor and reset the check engine light. After the car left the garage, I started my car an hour later and within a couple minutes, the light illuminated again with less than 2 km of driving it. I returned the car to the garage where they addressed another code that appeared, and with that, they changed the evap canister, reset the check engine light, and started the car only to have the light reappear. The mechanics are baffled as they are not sure what is bringing the light on again. They think it may be a wiring issue of some sort and are unable to get the wiring diagram as it is a canadian made car, and don't deal with the manufactures diagram. So far I had replaced the fuel cap, the air filter, had a recent oil change, replaced the 02 censor, and the evap canister. This car is in mint condition, had never been in an collision with all preventative maintenance conducted throughout the car's history. Any ideas on how to resolve the reoccurring check engine light?
Thank and look forward to your response.
