EGR Control Solenoid: Testing and Inspection

VSV INSPECTION

1. Remove VSV

2. Inspect VSV

A. Inspect VSV for open circuit






Using an ohmmeter. check that there is continuity between the terminals.

Resistance: 37 - 44 ohms at 20°C (68°F)

If there is no continuity, replace the VSV.

B. Inspect 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 VSV operation






a. Check that the air does not flows from ports E to F.






b. Apply battery voltage across the terminals.

c. Check that the air flows from ports E to F. If operation is not as specified, replace the VSV.

3. Reinstall VSV
