Intake Air Temperature Sensor: Description and Operation

Air Charge Temperature (ACT) Sensor

    This sensor, Fig. 2, provides the EFI system with air/fuel mixture temperature information. The air charge temperature sensor is used both as a density
corrector to air flow calculation and to proportion the cold enrichment fuel flow. This sensor is similar in construction to the engine coolant temperature
sensor.
