Code P0441

[ronjcar]

Well the beginning of the week my 04 libby threw this code. Reset it and was on my way. Then this morning when i get out of work it does it again. The first time i had been driving for about 30 minutes. This time it was right on startup. I've done some looking into it and some people are saying it could be water in my gas due to the weather finally breaking out of freezing temps. Other say something wrong with my evap system not purging. Any ideas how to narrow it down?

I guess check gas cap first and formost.

If the reseating the gas cap does not fix, and your lines to the Purge Solenoid and Evap Canister are good, change the Leak Detection Pump next, if not that, then change the Purge Solenoid. On my '04, it was the Leak Detection Pump....
