LESSON 3: POWERTRAIN

Monitoring The Substrate Temperature Sensor

Substrate Temperature Sensor

The TCM controls a number of high power solenoids and is surrounded by automatic transmission fluid. As a

result, the TCM can get very hot. If the temperature of the hardware rises above a predetermined temperature, the

TCM shuts down. Prior to shutting down, the TCM logs a fault code and illuminates the MIL. Following the shut

down, the transmission enters a mechanical limp-home mode. Monitoring of the substrate temperature is carried

out by a temperature-dependent resistor mounted in the processor.
