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.
