EGR Control Solenoid: Testing and Inspection

Component Inspection

EGR VOLUME CONTROL VALVE

With CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect EGR volume control valve harness connector.




3. Check resistance between EGR volume control valve terminal 2 and terminals 1, 3, terminal 5 and terminals 4, 6.
Resistance: 20 - 24 Ohms [at 20 °C (68 °F)]

If NG, replace EGR volume control valve.
If OK, go to next step.

4. Remove EGR volume control valve.
5. Reconnect ECM harness connector and EGR volume control valve harness connector.
6. Turn ignition switch ON.




7. Perform "EGR VOL CONT/V" in "ACTIVE TEST" mode with CONSULT-II.




8. Check that EGR volume control valve shaft moves smoothly forward and backward according to the valve opening steps.
If NG, replace EGR volume control valve.

Without CONSULT-II
1. Turn ignition switch OFF.
2. Disconnect EGR volume control valve harness connector.




3. Check resistance between EGR volume control valve terminal 2 and terminals 1, 3, terminal 5 and terminals 4, 6.
Resistance: 20 - 24 Ohms [at 20 °C (68 °F)]

4. Remove EGR volume control valve.
5. Reconnect ECM harness connector and EGR volume control valve harness connector.
6. Turn ignition switch ON and OFF.




7. Check that EGR volume control valve shaft moves smoothly forward,and backward according to the ignition switch position.
