Manifold Air Temperature Sensor Mat

Due to this location the sensor picks up engine heat and the air temp readings are incorrect or at the least not optimal.

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 manifold air temperature sensor or intake air temperature sensor provides the ecm with incoming air or fuel air mixture temperature. The manifold air temperature mat sensor is responsible for sending air temperature information to the ecm. 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.

It s located directly underneath the intake plenum. The sensor may be threaded onto the inlet manifold in which case it is called a manifold air temperature mat sensor. Its behavior is similar to that of the input air temperature sensor iat except that they have different. Includes rectangular style packard plug used on 1985 1991 l98 corvettes.

The iat sensor may be incorporated into the manifold absolute pressure map sensor when the latter is fitted on the inlet manifold. This can be identified by the presence of four pins as the map sensor requires only three.
