Diamante Sedan V6-2972cc 3.0L DOHC (1993)
Intake Air Temperature Sensor: Description and Operation
Intake Air Temperature Sensor Circuit
Purpose
The ECM uses the intake air temperature sensor signal to calculate fuel injection duration.
Operation
The intake air temperature sensor--a negative temperature coefficient thermistor--converts intake air temperature into a corresponding voltage
drop.
-
Sensor resistance--and the voltage dropped across the sensor--increases as temperature decreases.
