Diagnostic trouble code (DTC) information

Condition




The oil temperature sensor transmits a signal to the control module. This signal is used for functions such as temperature controlled lock-up and the engagement of high-temperature programs. The sensor has an NTC (negative temperature coefficient) resistor. The signal (voltage) decreases with increasing oil temperature. Diagnostic trouble code (DTC) TCM-0043 is stored if the control module receives too low a signal from the oil temperature sensor for approximately 20 seconds.

Substitute value
- No substitute values.

Possible source
- The power supply and signal cables are short-circuited to each other.
- Short-circuit to ground in the signal cable.
- Defective oil temperature sensor.

Fault symptom[s]
- General orange warning lamp lit.
- No lock-up function.
- Harsh gear shifting.

Hint: Harsh gear shifting can be caused by:
- No reduction of the line pressure when shifting.
- No reduction of the line pressure when moving the gear selector between positions P-R, N-R and N-D.
- No request for torque limiting to the engine control module (ECM) when shifting.
