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

PURPOSE AND LOCATION
The intake air temperature sensor (B17/7) which is located in the induction system measures incoming ambient air temperature. The information is used to calculate necessary adjustments to the air/fuel ratio and ignition timing. Low ambient air temperatures will tend to enrichen air/fuel mixtures and high ambient temperatures will tend to retard ignition timing.

SIGNAL
This signal is used by the LH control unit and transmitted via the controller area network (CAN) to the EZK/LKR control unit.
