EGR Control Solenoid: Testing and Inspection
EXHAUST GAS RECIRCULATION (EGR) SOLENOID VALVEINSPECTION
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 green-striped vacuum hose was connected.
4. Check airtightness 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 : 29.0 - 35.0 ohm [at 20 °C (68 °F)]
