Problem: Approximately 3 months ago I received the SES light with a P0445 Code (gross evap leakage) on my way home from camp (dirt roads). After I reset the code a few times it always came back before I eventually blew out the EVAP vent valve with compressed air. I got a pretty good amount of dirt to come out of it. I thought the problem was fixed. I also replaced the gas cap.
Now I'm getting P0446 code for circuitry trouble.
Before I go throwing parts at this thing, I'd rather get an honest opinion of what the problem could be. I'm mechanical inclined enough to replace the parts myself I'd just like to save a few trips to the dealer. I do usually fill the truck up with gas as full as I can get it - which leads me to believe that the EVAP canister is probably full of mud & gas.
Any opinions? Thanks.
