Transmission Temperature Sensor/Switch: Description and Operation
TRANSMISSION TEMPERATURE GAGEThe IPC displays the transmission temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the transmission temperature. The transmission temperature gage will default to 40°C (100°F) or below if:
- The PCM detects a malfunction in the transmission temperature sensor circuit.
- The IPC detects a loss of class 2 communications with the PCM.
