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), and insert a thermometer into the transaxle case hole.

NOTE: If a radiation thermometer (non contact 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).








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.
