Intake Air Temperature Sensor: Description and Operation
Fig. 2 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 and is mounted on an intake manifold runner or on the air cleaner.
