A/C Idle-Up Valve Inspection

A/C IDLE-UP VALVE INSPECTION

1. Remove idle-up valve.





(a) Disconnect the following connector and hoses:
(1) Idle-up valve connector.
(2) Air hose (from air cleaner hose) from port E of idle-up valve.
(3) Air hose (from air connector vent pipe) from port F of idle-up valve.
(b) Remove the bolt and idle-up valve.
2. Inspect 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 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 idle-up valve operation.





(a) Check that air does not flow from port E to port F.





(b) Apply battery positive voltage across the terminals.
(c) Check that air flows from port E to port F.
If operation is not as specified, replace the idle-up valve.
3. Reinstall idle-up valve.
