2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 498
Diagnosis information - PDK
Pressure sensor 1, short circuit to B+
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
- The following fault is not saved: P1706
- The following fault is not saved: P1707
Possible fault causes
- Line between pressure sensor 1 and PDK control unit faulty
- Pressure sensor 1 faulty
- PDK control unit faulty
- Clutch 1, measured oil pressure > 21 bar
Fault setting conditions
- Pressure sensor 1, signal > 4.5 V
Fault effects
- Engaged gear is held until vehicle stops
- Moving off possible only in 2nd gear
- Only gears 2, 4 and 6 are possible
- Start enable only in selector lever position P
- Transmission limp-home indication in instrument cluster control unit
