Intake Manifold 1 Temperature Sensor Circuit
Circuit Description
The intake manifold 1 temperature sensor monitors intake manifold air temperature and passes information to the engine control module (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 measures the temperature of the charge-air as it passes through the intake manifold. Possible causes of this fault include:
Restricted air flow through the charge air cooler
Undersized charge-air cooler
High turbocharger compressor outlet temperature.
Refer to Troubleshooting Fault Code t05-155.
