Thread: P0441 code / 1997 Grand Prix with 3.8 Ltr

Hi All,

I have a 1997 Grand Prix with a 3.8 engine (not supercharged) that has a P0441 code (only).

I checked the gas cap and it is tight.
What troubleshooting steps should I use to determine the cause?

Thanks, I know what the code means, but I'm not sure how to troubleshoot the problem. The gas cap is OK and all the lines look good, so I don't think I have a leak.

How can you determine if the Purge flow solenoid or Purge Switch is bad?
