SENSOR-TEMPERATURE/PRESSURE-MAP 

OPERATION 

INTAKE MANIFOLD AIR TEMPERATURE (IAT) SENSOR - ECM INPUT 

The combination, dual function Intake Manifold Air Temperature Sensor/MAP Sensor is installed into the top 
of the intake manifold with the sensor element extending into the air stream. 

The IAT portion of the sensor provides an input voltage to the Engine Control Module (ECM) indicating intake 
manifold air temperature. The MAP portion of the sensor provides an input voltage to the ECM indicating 
turbocharger boost pressure.
