2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 280
P173E
Diagnosis information - PDK
Transmission input shaft speed sensor, clutch 2, 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 detected: P1825
Possible fault causes
- Line between speed sensor 2 and PDK control unit faulty
- Speed sensor for clutch 2 faulty
- PDK control unit faulty
Fault setting conditions
- Sensor voltage > threshold value (> 4.5 V)
Fault effects
