TEST NS-7A - CHECKING IDLE AIR CONTROL MOTOR OPERATION
Note. Perform TEST NS-2A before proceeding.
- Hold throttle 1/4 depressed and attempt to start engine. If engine started and stayed running, go to next step. If engine did not start and stay running, go to TEST NS-8A.
- Release throttle and turn ignition off. Disconnect Idle Air Control (IAC) motor connector. Connect IAC motor connector to a known functional IAC motor. Turn ignition on. Using scan tool, actuate IAC motor. Observe tip of IAC motor. Go to next step.
- If IAC motor tip is moving in and out, replace original IAC motor. Perform TEST VER-1A. If IAC motor did not move in and out, check for other related IAC motor trouble codes. If other related IAC motor related trouble codes are present, repair as necessary. If no other related IAC trouble codes are present, replace Powertrain Control Module (PCM). Perform TEST VER-1A.
