Component Inspection

EGR SOLENOID CHECK

NOTE: When disconnecting the vacuum hose, always make a mark so that it can be reconnected at 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 white-striped vacuum hose was connected.




4. Check air tightness by applying a vacuum with voltage applied directly from the battery to the EGR control solenoid valve and without applying voltage.




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

Standard value: 62 - 74 ohm [at 20 °C (68 °F)]
