EGR Solenoid

EGR SOLENOID

EGR Solenoid Location:

1. Disconnect the yellow striped vacuum hose and the green striped vacuum hose from the solenoid valve.
2. Disconnect the electrical harness connector.
3. Connect a hand vacuum pump to the nipple which the green striped hose was connected to.
4. Connect jumper leads to the solenoid terminals.

EGR Control Solenoid Valve Voltage Test:

5. While applying vacuum to the solenoid, apply battery voltage directly to the solenoid terminals.
Vacuum should HOLD.
6. Discontinue voltage. Vacuum should LEAK.

EGR Control Solenoid Valve Resistance Check:

7. Measure the resistance between the terminals of the solenoid valve. Refer to ELECTRICAL SPECIFICATIONS.
