EGR Control Solenoid: Testing and Inspection

1. 4WD:
REMOVE BATTERY
2. REMOVE VSV
3. INSPECT VSV




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

Resistance: At 2O°C (68°F): 33 - 39 Ohm

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




- Apply battery positive voltage across the terminals.
- Check that air flows from port E to the filter. If operation is not as specified, replace the VSV.
4. REINSTALL VSV
5. 4WD:
