EVAP Canister Purge Solenoid Valve

EVAPORATIVE EMISSION PURGE SOLENOID







OPERATION
- The evaporative emission purge solenoid is an ON-OFF type one which controls introduction of purge air from the canister into the intake air plenum.
- The battery power is supplied to the evaporative emission purge solenoid through the MFI relay. When the engine control module turns ON the power transistor in the module, current flows to the coil, introducing purge air.




INSPECTION
Using Scan Tool

HARNESS INSPECTION




Measure the power supply voltage.
- Connector: Disconnected
- Ignition switch: ON
Voltage (V): Battery positive voltage
OK: GO TO STEP 2
NG: Repair the harness. (MFI relay - A1)




Check for an open-circuit, or a short-circuit to ground between the evaporative emission purge solenoid and the engine control module.
- Engine control module connector: Disconnected
- Evaporative emission purge solenoid connector: Disconnected
OK: STOP
NG: Repair the harness. (A2-16)
