Solenoid Test

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 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 evaporative emission canister purge solenoid valve and when the voltage is discontinued.

Battery Voltage Applied: Vacuum is released
Battery Voltage Not Applied: Vacuum is maintained

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

Coil resistance [at 20°C (68°F)]: 26 ohms
