EGR Control Solenoid: Testing and Inspection

COMPONENTS

1. REMOVE [1][2]VSV
2. INSPECT VSV




a. Inspect the [1][2]VSV for open circuit.
Using an ohmmeter, check that there is continuity between the terminals.

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

If there is no continuity, replace the [1][2]VSV.




b. Inspect the [1][2]VSV for ground.
Using an ohmmeter, check that there is no continuity between each terminal and the body.
If there is continuity, replace the [1][2]VSV.

c. Inspect the [1][2]VSV operation.




1. Check that air flows from ports E to G.




2. Apply battery positive voltage across the terminals.
3. Check that air flows from port E to filter.
If operation is not as specified, replace the [1][2]VSV.

3. REINSTALL [1][2]VSV
