Computer problem
2002 Chevy Cavalier 4 cyl Two Wheel Drive Automatic 59000 miles

I have a 2002 Chevy Cavalier with the check engine light on. I have found two broken wires on the small wireing loom by the fuel tank. I have installed a new fuel cap which I got from our state inspection station. I have disconneted the battery for about one hour to reset the computer, after about 90 miles the light comes back on. The computer code is P0440. Could my problem be in the evap purge solenoid or the canister is pluged. Any help would be a great help.

Most likely due to faulty vent solenoid. They tend to stick on this vehicle, preventing operation both directions. Tap with small tool and solenoid should start venting again
