Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor
PURPOSE
The intake air temperature sensor (B17) 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 fuel mixtures and high ambient temperatures will tend to
retard ignition timing.
SIGNAL
This signal is used by the HFM-SFI control module.
