IAC Valve TESTING:
1. Turn the ignition switch to the OFF position
2. Disengage the wiring harness connector from the IAC valve .
Using an ohmmeter, measure the resistance between the terminals of the valve. NOTE: Due to the diode in the solenoid, place the ohmmeter positive lead on the VPWR terminal and the negative lead on the ISC terminal.
3. If the resistance is not 7–13 ohms, replace the IAC valve.
