Manifold Air Temperature Sensor Mat

Replacement air temperature sensor for use with commander 950 or holley efi.

Manifold air temperature sensor mat.

The variable resistance sensor is also referred to as a charge temperature sensor air charge temperature sensor or air thermo sensor. The sensor may be threaded onto the inlet manifold in which case it is called a manifold air temperature mat sensor. It s located directly underneath the intake plenum. The iat sensor may be incorporated into the manifold absolute pressure map sensor when the latter is fitted on the inlet manifold.

Due to this location the sensor picks up engine heat and the air temp readings are incorrect or at the least not optimal. Includes rectangular style packard plug used on 1985 1991 l98 corvettes. What is the mat sensor. Its behavior is similar to that of the input air temperature sensor iat except that they have different.

This can be identified by the presence of four pins as the map sensor requires only three. The manifold air temperature sensor or intake air temperature sensor provides the ecm with incoming air or fuel air mixture temperature.
