EVAP System Leak Test
CAUTION:
DO NOT use compressed air. DO NOT start engine. DO NOT apply more than.6 psi (4.12 kPa) of pressure to EVAP system.
Using EVAP Service Port Adapter (J41413-OBD), connect suitable pressure pump with gauge to EVAP service port. See VACUUM DIAGRAMS article for location. Disconnect EVAP Canister Vent Control Valve (EVAP-CVCV) and vacuum cut valve by-pass valve harness connectors. See Fig 1 or Fig 2 . Using jumper wires, apply battery voltage to EVAP-CVCV and Vacuum cut valve by-pass valve terminals. Apply.2-.4 psi (1.38-2.76 kPa) of pressure to EVAP service port. Remove pressure pump from EVAP service port. Using Leak Detector (J41416), locate EVAP system leak.
