Component Tests and General Diagnostics

1. REMOVE A/C IDLE-UP VALVE.
- Disconnect the idle-up valve connector.
- Disconnect the 2 air hoses.
- Remove the 2 bolts and idle-up valve.





2. INSPECT A/C IDLE-UP VALVE.
A. Inspect idle-up valve for open circuit.
- Using an ohmmeter, check that there is continuity between the terminals.

Resistance: At 20°C (68°F): 30 - 34 ohms

- If there is no continuity, replace the idle-up valve.





B. Inspect A/C idle-up valve for ground.
- Using an ohmmeter, check that there is no continuity between each terminal and the body.
- If there is continuity, replace the idle-up valve.





C. Inspect A/C idle-up valve operation.
- Check that air does not flow from port E to port F.





- Apply battery positive voltage across the terminals.
- Check that air flows from port E to port F.
- If operation is not as specified, replace the idle-up valve.
3. REINSTALL A/C IDLE-UP VALVE.
- Install the idle-up valve with the 2 bolts.

Torque: 20 Nm (15 ft lb)

- Connect the 2 air hoses.
- Connect the idle-valve connector.
