Circuit Description
The intake manifold temperature sensor is used by the ECM to monitor the temperature of the engine intake air. The intake manifold temperature signal is used by the ECM for the engine protection system, timing, and fueling control.
Component Location
The intake manifold temperature sensor is located on the top front half of the intake manifold.
