Idle Up Control Valve: Testing and Inspection

A/C IDLE-UP VALVE INSPECTION
1. Remove Idle-Up Valve.




2. Inspect idle-Up valve for open circuit.




- Using an ohmmeter, check that there is continuity between the terminals.
Resistance: 30 - 34 Ohms at 20°C (68°F)
^ If there is no continuity, replace the idle-up valve.
3. Inspect 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.
4. Inspect idle-up valve operation.




- Check that the air does not flow from port E to port F.




- Apply battery voltage across the terminals.
- Check that the air flows from port E to port F.
^ If operation is not as specified, replace the idle-up valve.
4. Reinstall idle-up valve.
