EVAP Solenoid Check

Attach hose to vapor line that comes from canister to solenoid and attempt to blow into it. Air should not pass into solenoid. If air passes through solenoid, then replace solenoid.

With engine off, go into EVAP solenoid override (PO01). Override of solenoid should cause solenoid to vibrate. Physically touch solenoid (mounted in engine compartment) in override condition. If solenoid is not vibrating, then replace solenoid.
