Intake Air Temperature Sensor

Intake Air Temperature (IAT) sensor is incorporated into Volume Air Flow (VAF) sensor assembly. This resistor-based sensor measures temperature of incoming air and sends an analog signal to PCM. Depending on configuration, IAT input may be used for fuel injection, idle air, and/or ignition timing control.
