EGR Control Solenoid: Testing and Inspection

INSPECTION

1. REMOVE VSV
2. INSPECT VSV




a. Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity between terminals.

Resistance: 33 - 39 Ohm at 20 °C (68 °F)

If there is no continuity, replace the VSV.




b. Inspect the VSV for ground.
Using an ohmmeter, check that there is no continuity between each terminal and the body.

If there is continuity, replace the VSV.




c. Inspect the VSV operation.
1. Check that air does not flow from ports E to F.




2. Apply battery positive voltage across the terminals.
3. Check that air flows from ports E to F.

If operation is not as specified, replace the VSV.

3. REINSTALL VSV
