Wastegate Solenoid: Testing and Inspection

VACUUM SWITCHING VALVE (VSV) INSPECTION



1. REMOVE VSV ASSEMBLY.

2. INSPECT VSV.
A. Inspect VSV for open circuit.



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

Resistance at 20°C (68°F): 22 - 26 Ohms

- 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 does not flow from port E to port F.



- Apply battery voltage across the terminals.
- Check that air flows from ports E to F.
- If operation is not as specified, replace the VSV.

3. REINSTALL VSV ASSEMBLY.
