Mass Air Flow (MAF) and Intake Air Temperature (IAT)

Transaxle Electronic Control System

Mass Air Flow (MAF) and Intake Air Temperature (IAT)

The MAF sensor is located between the air cleaner housing and the air intake hose leading to the throttle housing.

The IAT sensor is incorporated in the housing of the MAF sensor.

The MAF sensor in conjunction with the IAT sensor provides the PCM with the primary load signal.

The PCM uses the signals for the following functions among other things:

- to control the shift operations.
- to control the main line pressure.

If the MAF sensor fails, the signal of the TP sensor is used as a substitute.
