EGR Solenoid Valve

1. Disconnect the vacuum hose (green stripe) from the solenoid valve and connect a hand vacuum pump to the fitting.
2. Disconnect the electrical connector.





3. Apply battery voltage to the electrical connectors as shown.
4. Apply vacuum to the solenoid with a pump and note the results.

Vacuum should hold when voltage is applied.
Vacuum should NOT hold when voltage is removed.

EGR Resistance Test:

5. Using an ohm meter check the resistance across the solenoid terminals.

Resistance: 36 - 44 ohms at 20°C (68°F)
