P0710 TRANSMISSION FLUID TEMPERATURE SENSOR A

P0710 TRANSMISSION FLUID TEMPERATURE SENSOR A

Description

INFOID:0000000009948960

• CVT fluid temperature sensor is installed to control valve.
• CVT fluid temperature sensor detects CVT fluid temperature in oil pan.
• The CVT fluid temperature sensor converts CVT fluid temperature into output voltage and transmits the sig-

nal to TCM.

• The CVT fluid temperature sensor uses a thermistor and its electrical resistance varies as the temperature

varies. The electrical resistance decreases as the temperature increases.
