2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 386
Fault effects
- Engaged gear is held until vehicle stops
- Start enable only in selector lever position P
- Transmission limp-home indication in instrument cluster control unit
Pressure Sensor 3, Signal Implausible
P181C
Diagnostic information - PDK
Pressure sensor 3, signal implausible
Diagnostic conditions
The control unit initially tests internal function sequences when the ignition is switched on (terminal 15). If they are OK, all diagnosable outputs are
then tested and any faults are stored.
- Ignition on
Possible fault causes
- Line between pressure sensor 3 and PDK control unit faulty
- Pressure sensor 3 faulty
- PDK control unit faulty
- Hydraulic control unit Faulty
Fault setting conditions
- Measured pressure deviates from the internal plausibility check. Permitted limit was exceeded.
Fault effects
- Engaged gear is held until vehicle stops
- Start enable only in selector lever position P
- Transmission limp-home indication in instrument cluster control unit
