Variable Induction Control Solenoid: Testing and Inspection

ACIS VACUUM SWITCHING VALVE (VSV) TESTING AND INSPECTION

1. REMOVE VACUUM TANK AND VSV ASSEMBLY
2. REMOVE VSV
- Remove the screw, vacuum hose and VSV.
3. INSPECT VSV
A. Inspect VSV for open circuit

Ohmmeter Connections:

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

Resistance: At 20°C (68°F) 38.5 - 44.5 Ohms

- If there is no continuity, replace the VSV.
B. Inspect VSV for ground

Ohmmeter Connection:

- 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

Air Flows Freely:

- Check that air flows from port E to the filter.

Battery Connections:

- Apply battery positive voltage across the terminals.
- Check that air flows from port E to F.
- If operation is not as specified. replace the VSV.
4. REINSTALL VSV
5. REINSTALL VACUUM TANK AND VSV ASSEMBLY
