Transmission Temperature Sensor/Switch: Testing and Inspection

TRANSMISSION FLUID TEMPERATURE SENSOR CHECK





1. While pressing A in the figure, turn B counterclockwise to unlock the CVT assembly connector, and disconnect the connector.

CAUTION

Insert a thermometer which is made of metal or is put in a metal case (overall length: approximately 150 - 200 mm) into the transaxle case hole approximately 80 mm.

2. Remove the oil filler tube assembly (Refer to Transaxle Assembly), and insert a thermometer into the transaxle case hole.

NOTE: If a radiation thermometer (noncontact thermometer) is available, use it to measure the surface temperature of the oil pan.

3. Measure the resistance between the sensor-side connector terminal No.17 of the CVT assembly connector and ground (terminal No.19).

Standard value:





NOTE: In the information screen on the multi-information display, the fluid temperature warning comes on when the transmission fluid temperature is approximately 140°C (284°F) or higher, and automatically goes out when the transmission fluid temperature dropped below approximately 137°C (279°F).

CAUTION
The transmission fluid temperature sensor cannot be removed or replaced as a single unit. When the transmission fluid temperature sensor needs to be replaced, replace the valve body assembly.

4. When the resistance of the transmission fluid temperature sensor is outside the standard value, and the fluid temperature warning comes on/goes out at other than the specified temperatures, replace the valve body assembly and the harness.
