I'm receiving a CEL code of P0446: "Evaporative Emission Control System Vent Control Circuit" in my 2001 Trooper with 56,000 miles. Yes, I know about the loose gas cap issue...I even replaced the gas cap to make sure but I'm still receiving the CEL. I'm thinking it's either a vent line from the gas tank to the carbon canister or the actual sensor that's bad. Anyone else have similar problems with their Trooper? Where's the carbon canister and associated vent line in this year Trooper? the sensor? Any help would be much appreciated.
