2001 Volvo C70 Coupe L5-2.3L Turbo VIN 53 B5234T3SECTION Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information
Condition
The automatic transmission control module (TCM) receives speed signals from the transmission speed sensor on the transmission. The transmission control module (TCM) uses the signals to select the correct gear. The control module derives and compares the transmission speed with engine speed (RPM) at the transmission. Diagnostic trouble code (DTC) TCM-0081 is stored if the control module registers that transmission speed signal is too high.
Substitute value
- None.
Possible source
- Short-circuit to supply voltage in the power supply or signal cable.
- Defective transmission speed 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 line pressure when shifting.
- No reduction of line pressure when moving the gear selector between positions P-R, N-R and N-D.
- No torque limiting request to engine control module (ECM) when shifting.
