Air Temperature Sensor ( Ambient / Intake ): Description and Operation

INTAKE AIR TEMPERATURE SENSOR-PCM INPUT

Intake Air Temperature Sensor and MAP Sensor-2.0L:

The IAT sensor and Manifold Absolute Pressure (MAP) sensor are a combined sensor that attach to the intake manifold for 2.0L engine.

Intake Air Temperature Sensor and MAP Sensor-2.4L:

Intake Air Temperature Sensor and MAP Sensor-2.5L:

The IAT sensor threads into the intake manifold for the 2.4/2.5L engines.

The Intake Air Temperature (IAT) sensor measures the temperature of the intake air as it enters the engine. The sensor supplies one of the inputs the PCM uses to determine injector pulse width and spark advance.
