Canister Purge Solenoid: Testing and Inspection

NOTE: When disconnecting the vacuum hose, always make a mark so that it can be reconnected at original position.

1. Disconnect the vacuum hose (black stripe, red stripe or rep paint mark) from the solenoid valve.
2. Disconnect the harness connector.





3. Connect a hand vacuum pump to nipple (A) of the solenoid valve (refer to the illustration at left).
4. Check airtightness by applying a vacuum with Voltage applied directly from the battery to the purge control solenoid valve and without applying Voltage.

Battery Voltage Condition
Applied Vacuum leaks
Not applied Vacuum maintained





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

Standard value: 36-44 Ohms [at 20°C (68°F)]
