When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
The DTC will set when the monitored Temperature Sensor voltage fluctuatesor changes abruptly within a pre-
determined period of time.
Possible Causes
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.
