DTC P0711: Transmission Fluid Temperature (TFT) Sensor Performance
Circuit/System Description
The transmission fluid temperature (TFT) sensor is located inside of the transmission control module (TCM) assembly and has no serviceable parts. The TFT sensor provides transmission fluid temperature to the TCM. This fault is handled inside
the TCM and no external circuits are involved.
