Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor Location
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 module and transmitted via the controller area network (CAN) to the EZL/AKR control module.
