EGR Control Solenoid: Testing and Inspection

EGR SOLENOID CHECK

NOTE: When disconnecting the vacuum hose, make an identification mark on it so that it can be reconnected to the original position.

1. Disconnect the vacuum hose 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. Apply a vacuum and check for air-tightness when voltage applied directly to the EGR solenoid and when the voltage is discontinued.




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

Standard value: 36 - 44 Ohms [at 20°�C (68° F)]
