Tercel Sedan 2-Door L4-1497cc 1.5L DOHC (5E-FE) (1995)
Intake Air Temperature Sensor: Description and Operation
PURPOSE
The Intake Air Temperature Sensor sends a signal to the Engine Control Module (ECM) indicating the temperature of intake air. The ECM uses
this signal to control Air/Fuel ratio to maintain optimum performance in all conditions.
OPERATION
The resistance of the thermistor decreases as the air intake temperature increases. The ECM uses this decreasing resistance to calculate the
adjustment to the length of injector opening time necessary.
