My first post in a while.

1999 Grand Prix GTP 223,000 miles

I have a SES code of 0440 that was pulled at Autozone. Just got back from my neighboorhood auto repair shop who informed me (after doing a smoke test) that i needed the vapor canister and vent valve replaced. He quoted over 500 bucks to do the job. I asked why so much and he said he had to drop the gas tank to get at the parts.

In doing some research, I found that the unit is behind the drivers side rear tire and can be access by removing the tire and pulling the plastic liner.

Does anyone know who is correct.
