Intake Air Temperature (IAT) Sensor

DESCRIPTION
The Intake Air Temperature (IAT) Sensor provides the sequential fuel injection (SFI) system with mixture (fuel and air) temperature information. The intake air temperature sensor is used both as a density corrector for air flow calculation and to proportion cold enrichment fuel flow. The intake air temperature sensor is installed in the air cleaner outlet tube and provides the fuel system with mixture temperature information. The intake air temperature sensor is used in determining electronic pressure control (EPC) pressure.
SYMPTOMS
Incorrect EPC pressure, either high or low, will result in either harsh or soft shifts.
