Was bedeutet der Fehlercode?
The pressure sensor for the clutch for even gears gives too high a signal to the transmission control module (TCM). The sensor shows the pressure on the clutch, so a wrong value means the control module does not get the right information to control it. The cause may be a sensor wire short-circuited to supply voltage or a damaged sensor.
Mögliche Ursachen
- Pressure sensor short-circuited to supply voltage
- Pressure sensor for the clutch for even gears is damaged
Was Sie tun können
- 1Read out the fault codes from the transmission control module and deal first with any codes that may share the same cause
- 2Use a multimeter to check that the wire to the pressure sensor for even gears has no contact with the battery's positive supply
- 3The fault points to a damaged pressure sensor or a fault at its connection; the mechatronic unit must then be replaced, which a workshop should do
- 4If the fault is inside the control module, it must be replaced, and a new module is delivered without software and must be programmed by a workshop
Symptome, die Sie bemerken können5

- Gears shift hard or jerky, sometimes or all the time
- No automatic gear changes
- Gear changes take too long to complete, sometimes or all the time
- Shifts occur too early, too late or too often, sometimes or all the time
