Continuous Memory Diagnostic Trouble Code (DTC) P0442 indicates that a fuel
vapor leak has been detected [as small as 0.10 cm (0.04 inch)] in the
Evaporative Emission (EVAP) system.
Note: Prior to performing the following diagnosis inspect the Canister
Vent Solenoid (CV) for contamination. A situation may exist where contamination
holds open the Canister Vent (CV) solenoid enough to set DTC P0442 and also
plugs the port to atmosphere enough to keep system from being vented quickly.
