Idle Up Control Valve: Testing and Inspection

VSV Inspection - Checking Resistance:

Inspect VSV For Open Circuit
- Using an ohmmeter, check that there is continuity between the terminals.

Resistance (Cold): 30 - 34 ohms

- If there is no continuity, replace the VSV.

VSV Inspection - Checking For Short:

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.

VSV Inspection - Checking Operation:

Inspect VSV Operation
- Check that the air does not flow from port A to port B.

VSV Inspection - Checking Operation:

- Apply battery voltage across the terminals.
- Check that the air flows from port A to port B.
- If operation is not as specified, replace the VSV.
