Intake Air Temperature (IAT) Sensor

DESCRIPTION
The Intake Air Temperature (IAT) sensor provides the Sequential Fuel Injection (SFI) system mixture temperature information. The IAT sensor is used both as a density corrector for air flow calculation and to proportion cold enrichment fuel flow. The IAT sensor is installed in the air cleaner outlet tube. The IAT sensor is also used in determining Electronic Pressure Control (EPC) pressures.

SYMPTOMS
Incorrect EPC pressure, either high or low, will result in either harsh or soft shifts.
