Good day,
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.

Matt

I will help you the best I can we can't get European Canadian etc made cars info. But what are the exact code numbers you have now in the computer? It will be a letter followed by a four digit number?

Thanks for your quick response!
The initial codes detected were:
P0455
P2610
P0135
P0449
This was scanned by a friend who had a portable diagnostic computer.
I then took my vehicle to a certified mechanic and they to diagnosed the car, however, I'm not sure if the exact same codes showed up on their diagnostic scanner. They assured me that all codes that showed up on their scanner had been addressed, but the light will not extinguish.
They did replace just one 02 sensor. It is my understanding that this model has 2. Is it possible that the other 02 sensor needs replacement or they may have changed out the wrong sensor?

Thanks.

The 455 is a evap code like a large leak the 449 is a vent solenoid code I believe.I will have to look them up but they have nothing to do with the O2 sensor. The135 is a o2 sensor code I need to know what codes are present now?Let's go from there.

Perfect. I'll talk to the mechanics on Monday regarding what codes showed up as they're closed on the weekend.
Thanks again for your response!
