2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 502



- Start enable only in selector lever position P



- Transmission limp-home indication in instrument cluster control unit



Pressure Sensor Clutch 2, Signal Implausible



P0846



Diagnosis information - PDK



Pressure sensor clutch 2, 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 2 and PDK control unit faulty



- Pressure sensor 2 faulty



- PDK control unit faulty



Fault setting conditions



- Measured pressure deviates from the internal plausibility. Permissible limit value was exceeded.



Fault effects



- Engaged gear is held until vehicle stops



- Moving off possible only in 3rd gear



- Only gears 1, 3, 5 and 7 are possible



- Start enable only in selector lever position P



- Transmission limp-home indication in instrument cluster control unit
