Oil Temperature Sensor

The oil temperature sensor is of the thermistor type, and senses the automatic transaxle fluid temperature. Using the signal from this sensor, TCM (PCM) controls the shift pattern optimally during shift. In order to operate the damper clutch, this signal is also referred.

• Range of temperature: -40°C~145°C
• Type: Separated type (High / Low temperature)
• Standard value of internal resistance
