Intake Air Temperature Sensor: Description and Operation
Fig. 1 Air charge temperature (ACT) sensor
The ACT sensor, Fig. 1, used on EFI models, provides the EFI system mixture (air/fuel) temperature information. The ACT is used as both as a
density corrector to air flow calculation and to proportion the cold enrichment fuel flow. This sensor is mounted on an intake manifold runner or on the
air cleaner.
