EGR Control Solenoid: Testing and Inspection

EGR SOLENOID CHECK
1. Disconnect the vacuum hose 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 nipple (A) of the EGR solenoid. (Refer to the illustration.)




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: 29 - 35 ohm [at 20 °C (68 °F)]

6. Replace the solenoid if resistance is out of specification.
