2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 275
- Ignition on
Possible fault causes
- Short circuit in line between oil temperature sensor and PDK control unit
- Oil temperature sensor faulty
Fault setting conditions
- Measured voltage > threshold value (2.35 V)
Fault effects
- Substitute value is used
- Clutch pressure < holding threshold 8.1 bar and torque limitation
- Transmission limp-home indication in instrument cluster control unit
Transmission Input Shaft Speed Sensor, Clutch 1, Short Circuit To B+
P173B
Diagnosis information - PDK
Transmission input shaft speed sensor, clutch 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

- Speed sensor for clutch 1 faulty
- PDK control unit faulty
Fault setting conditions
- Sensor voltage > threshold value (> 4.5 V)
Fault effects
- Electrical substitute value
- No gear preselection
- No R gear
- Transmission limp-home indication in instrument cluster control unit
