Vane Air Temperature Sensor: Description and Operation
Vane Air Temperature (VAT) Sensor
PURPOSE
The Vane Air Temperature (VAT) sensor measures inlet air temperature and provides an input signal to the ECA. The signal is used by the ECA
in calculations for air/fuel ratio, fuel pressure, purge control, and idle speed.
OPERATION
Sensor is a device whose resistance changes with temperature. The ECA interprets these variations as temperature fluctuations.
