Intake Manifold 1 Temperature Sensor Circuit
Circuit Description
The intake manifold 1 temperature sensor monitors intake manifold air temperature and passes information to the ECM through the engine harness.
Component Location
The intake manifold 1 temperature sensor is located in the air intake manifold. Use the following procedure for a detailed component location view. Refer to Procedure 100-002 in Section E.
Shop Talk
The intake manifold 1 temperature sensor shares return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Check fault codes with multiple counts first.
Possible causes of this fault code include:
Signal circuit shorted to ground in the harness.
Signal circuit shorted to return or ground in the sensor.
