Solenoid 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, red stripes) from the solenoid valve.
2. Disconnect the harness connector.




3. Connect a hand vacuum pump to the nipple to which the vacuum hose with red-stripes was connected.




4. Check airtightness by applying a vacuum with voltage applied directly from the battery to the evaporative emission purge solenoid and without applying voltage.

Battery Voltage Normal 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 2O°C (68°F)
