EGR Control Solenoid: Testing and Inspection

TROUBLESHOOTING HINT
If the results of EGR solenoid on-vehicle and off-vehicle inspections are normal but the self diagnostic trouble code for EGR system failure is displayed, check the EGR valve, vacuum hose and EGR passage for blocking.

EGR Solenoid Location:





ACTUATOR INSPECTION
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.

Standard Value: 36 - 44 ohms at 20° C (68° C)
