Idle Speed Motor Position Sensor: Testing and Inspection
TROUBLESHOOTING HINTS
HINT 1: The IAC valve position sensor is the most important sensor for controlling idle speed. If a malfunction develops when the engine is
idling and the engine load is varied by turning the air conditioning switch to ON and OFF etc. this sensor is probably defective.
NOTE: In a new vehicle [driven approximately 500 km (300 miles) or less] the IAC valve position sometimes exceeds the standard value by
approximately 20 steps.
CAUTION: When shifting the selector lever to the D range apply brake to prevent the vehicle from moving forward.
