Circuit Description
The intake manifold pressure/temperature sensor is used by the electronic control module (ECM) to monitor the engine intake air temperature. The intake manifold temperature signal is used by the ECM for engine protection system, cold start aid, timing, and fueling control.
Component Location
The intake manifold pressure/temperature sensor is located in the intake air housing.
