PO496

Post by sardillim » Thu Jul 20, 2017 1:58 am

Getting this code, it appears that it is on cold start up only. My guess is that the evap leak fixes itself when things warm up which makes if difficult to find any type of leak. Anybody have this code pop up ? if so what was the fix ?

Thanks

May want to search the G8 boards. I know the V8 guys have had a consistent issue with the purge valve. Not sure what the V6 guys have been experiencing. Just more history there.

If you want any of the diagnostic steps let me know I can post the flow chart if you got a multi-meter.
