When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
The DTC will set when the monitored Temperature Sensor voltage rises above4.94 volts for the period of 1.45
seconds. When the fault is set, calculated temperature is substituted formeasured temperature, however the
fault code is stored only after three consecutive occurrences of the fault.
Possible Causes
(K900) SENSOR GROUND OPEN
(T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT OPEN
(T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT SHORT TO VOLTAGE
TRANSMISSION TEMPERATURE SENSOR
POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The temperature sensor is used to sense the temperature of the transmission fluid. Transmission fluid temperature
can affect shift quality, torque converter operation and when or if some diagnostics are run. A failed temperature
sensor could affect the OBD diagnostics. If a problem occurs in the transmission temperature sensor circuit, trans-
mission temperature will be based on a calculated value.
