EGR Control Solenoid: Testing and Inspection

1. REMOVE VACUUM SWITCHING VALVE (VSV) ASSEMBLY.





- Disconnect the 2 connectors and 4 vacuum hoses, and remove the 2 bolts and VSV assembly.
2. INSPECT VSV.
- Inspect VSV for open circuit.





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

Resistance:At 20°C (68°F): 33 - 39 Ohms

- If there is no continuity, replace the VSV.
- 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.
- Inspect VSV operation





- Check that air flows from port E to port 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.
3. REINSTALL VSV ASSEMBLY.
- Install the VSV assembly with the 2 bolts.

Torque: 8 Nm (71 in lb)

- Connect the 2 connectors and 4 vacuum hoses to the 2 VSV.
