Camaro V6-3.8L VIN K (1995)
Idle Speed/Throttle Actuator - Electronic: Testing and Inspection
The scan tool displays IAC pintle position in counts. "0" counts indicates the PCM is commanding the IAC pintle to be driven all the way into a fully
seated position. This is usually caused by a vacuum leak.
The higher the number of counts, the more air is being commanded to bypass the IAC pintle.
Refer to DTC P0506, DTC P0507, DTC P1508, and DTC P1509 in order to diagnose the IAC system. See: Testing and Inspection
Refer to Rough, Unstable, or Incorrect Idle, Stalling in Symptoms, for other possible causes of idle problems. See: Testing and Inspection
