EGR Control Solenoid: Testing and Inspection

EGR SOLENOID CHECK
1. Disconnect the vacuum hose (black, yellow stripe) from the EGR solenoid.

NOTE: When disconnecting the vacuum hose, always make sure that it can be reconnected at its original position.

2. Disconnect the harness connector.







3. Connect a hand vacuum pump to the nipple A of the EGR solenoid. (Refer to the illustration at left.)




4. Check airtightness by applying a vacuum with voltage applied directly from the battery to the EGR solenoid and without applying voltage.
5. Measure the resistance between the terminals of the EGR solenoid.

Standard value: 30 - 34 ohm [at 20°C (68°F)]

6. Replace solenoid if resistance is out of specification.
