EGR Control Solenoid: Testing and Inspection
EGR Control Solenoid Valve Inspection
EGR Solenoid
1.
Disconnect the yellow and green striped vacuum hose from the solenoid valve.
2.
Disconnect the harness connector from the solenoid.
3.
Connect a hand vacuum pump to the nipple.
4.
Apply a vacuum and observe vacuum gauge while applying battery voltage across the solenoid terminals with jumper wires.
- Vacuum should hold while voltage is connected.
- Vacuum should not hold while voltage is disconnected.
5.
Measure the resistance between the solenoid terminals.
Acceptable Resistance Range
@ 20° C (68° F) ....................................................................................................................................................................................... 36 - 44 ohms
6.
If the solenoid failed any test, replace solenoid.
