Mat sensor manifold air temperature sensor also called as iat sensor intake air temperature sensor.
Manifold air temperature sensor mat.
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.
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.
Due to this location the sensor picks up engine heat and the air temp readings are incorrect or at the least not optimal.
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.
The iat sensor may be incorporated into the manifold absolute pressure map sensor when the latter is fitted on the inlet manifold.
What is the mat sensor.
Replacement air temperature sensor for use with commander 950 or holley efi.
It s located directly underneath the intake plenum.
