Monitor Description

These DTCs indicate an open or short in the transmission fluid temperature sensor circuit. The transmission fluid temperature sensor converts the transmission fluid temperature to an electrical resistance value. Based on the resistance, the hybrid vehicle control ECU determines the transmission fluid temperature. The hybrid vehicle control ECU also detects an open or short in the transmission fluid temperature circuit based on the resistance. If the resistance value of the transmission fluid temperature sensor is outside a specified range, the hybrid vehicle control ECU interprets this as a fault in the transmission fluid sensor or wiring. The hybrid vehicle control ECU will turn on the MIL and store a DTC.

HINT: 

The transmission fluid temperature can be checked using an OBD II scan tool, or the Techstream.
