Manifold Air Temperature Sensor Mat

The iat sensor may be incorporated into the manifold absolute pressure map sensor when the latter is fitted on the inlet manifold.

Manifold air temperature sensor mat.

The multiple air temperature sensor or mat is a thermistor that is located at the junction of the air filter and thus allows the ecm engine control module to balance exactly the air flow readings all this is done based on the temperature of the incoming air. This can be identified by the presence of four pins as the map sensor requires only three. Mat sensor manifold air temperature sensor also called as iat sensor intake air temperature sensor. The sensor may be threaded onto the inlet manifold in which case it is called a manifold air temperature mat sensor.

Includes rectangular style packard plug used on 1985 1991 l98 corvettes. The manifold air temperature sensor or intake air temperature sensor provides the ecm with incoming air or fuel air mixture temperature. The variable resistance sensor is also referred to as a charge temperature sensor air charge temperature sensor or air thermo sensor. Replacement air temperature sensor for use with commander 950 or holley efi.

Due to this location the sensor picks up engine heat and the air temp readings are incorrect or at the least not optimal. The manifold air temperature mat sensor is responsible for sending air temperature information to the ecm.
