A/C Idle-Up Valve

Remove A/C idle-up valve. A/C idle-up valve is located at passenger's side front corner of engine, bolted to air intake chamber near throttle body and contains a Black 2-Pin electrical connector. See Figure.
Using ohmmeter, ensure continuity exists between electrical terminals on A/C idle-up valve and resistance is 30-34 ohms at 68°F (20°C). Replace A/C idle-up valve if no continuity exists or resistance is not within specification.
Ensure no continuity exists between each electrical terminal and body of A/C idle-up valve. Replace A/C idle-up valve if continuity exists between electrical terminal and body of A/C idle-up valve.
Apply air pressure to port "E" without battery connected. Ensure no air flows from port "F". See Fig 1.
Apply battery voltage and ground to electrical terminals on A/C idle-up valve. Apply air pressure to port "E". Ensure air flows from port "F". See Fig 1. Replace A/C idle-up valve if defective.
