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)
