Transaxle Oil Temperature Sensor: Description
The oil temperature sensor (A) detects the automatic transaxle fluid temperature. The oil temperature sensor is a negative thermal coefficient type. The resistance of the sensor increases when the oil temperature goes down and the resistance goes up when the oil temperature decreases.
Using the signal from this sensor, PCM corrects the solenoid drive duty when the fluid is cold (lower than 60°C) and hot (higher than 125°C). PCM restricts the shift pattern to the economy mode when the fluid is cold .
