ELECTRICAL SYSTEM COMPONENTS
TRANSMISSION FLUID TEMPERATURE (TFT)
SENSOR
lnspection
1. Access TFT PID.
2. Monitor the TFT PID voltage as the engine warms to
normal operating temperature.
Specification:
3. If TFT PID does not increase as engine reaches normal
operating temperature, replace TFT sensor.
Replacement
The TFT sensor is a part of the main control valve body
wiring harness. (Refer to K-152.)
