Component Inspection

INSPECTION





1. Disconnect Negative (-) Terminal Cable From Battery

CAUTION: Work must be started after 90 seconds from the time the ignition switch is turned to the LOCK position and the negative (-) terminal cable is disconnected from the battery.

2. Remove Air Conditioning Idle-Up Valve.





- Disconnect the idle-up valve connecter.
- Disnonnect the 2 air hoses.
- Remove the 2 bolts and idle-up valve.





3. Inspect Idle-Up Valve for open circuit. Using an ohmmeter, check that there is continuity between the terminals.

Resistance; 30 - 33 Ohms at 20°C (68°F)

If there is no continuity. replace the Idle-Up Valve.





4. Inspect Air Conditioning 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.
5. Inspect Air Conditioning 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 DOES flow from port E to port F. If operation is not as specified. replace the Air Conditioning Idle-Up Valve.
