Air Temperature Sensor ( Ambient / Intake ): Description and Operation

INTAKE AIR TEMPERATURE SENSOR (X311)

The Intake Air Temperature Sensor is a dedicated sensor, mounted on the air cleaner housing. The Intake Air Temperature Sensor is a resistive sensor, i.e. the change in resistance is related to change in air temperature. The signal from the Intake Air Temperature Sensor (X311) is used to retard the ignition timing if the air temperature rises above 55° C.
