Default Evap Control System
I received diagnostic trouble codes: 1) P0440-Evap Control System Malfunction,
2) P0441 Evap Control System Incorrect Purge Flow.
3) P0446 Evap Control System Vent Control Circuit Malfuction
I believe these are causing extra fuel to be burned. I notice when I go up a hill, enter the freeway, or speed up quickly I smell fuel. Could this be a purge sensor? ???

Most often, P0441 and P0446 are resolved by simply tighten or replace the gas cap.

Attached are troubleshooting steps from the repair manual for the EVAP...

was there ever any conclusion to the root cause of the 12V lighter fuse blowing?
