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 (yellow stripe, green stripe) from the solenoid valve.
2. Disconnect the harness connector.





3. Connect a hand vacuum pump to the nipple to which the green-striped vacuum hose was connected.
4. Check airtightness by applying a vacuum with voltage applied directly from the battery to the EGR solenoid and without applying voltage.

Battery voltage Normal condition

Applied Vacuum maintained
Not applied Vacuum leaks





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

Standard value: 62-74 ohms (at 20°C (68°F))
