Diagnostic Aids
To locate an intermittent problem, command EVAP Vent Solenoid ON and OFF with the ignition ON and the engine OFF, with the scan tool. Wiggling wires while listening for the EVAP vent solenoid to stop clicking may locate a shorted solenoid or the area where a short to voltage in the wiring may exist.
For intermittent conditions refer to INTERMITTENT Conditions.
