Canister Purge Solenoid: Testing and Inspection

INSPECTION






NOTE: When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to its original position.

1. Disconnect the vacuum hose (black with red stripe) from the solenoid valve.
2. Detach the harness connector.
3. Connect a vacuum pump to the nipple to which the red-striped vacuum hose was connected.







4. Apply vacuum and check when voltage is applied to the EVAP Canister Purge Solenoid Valve and when the voltage is discontinued.




5. Measure the current between the terminals of the solenoid valve.

EVAP Canister Purge Solenoid Valve:
Coil at 20 °C (68 °F) 0.45 A or below (at 12 V)
Coil resistance 23 - 26 ohms [at 20 °C (68 °F)]





EVAPORATIVE EMISSION CANISTER PURGE SOLENOID VALVE
The evaporative emission canister purge solenoid valve is a duty control type, which controls purge air from the evaporative emission canister
