2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 281
Short circuit to ground:
- Setpoint resistance > 0.9 MOhm
Open circuit:
- Setpoint resistance < 2 Ohm
NOTE: The specified values apply only at an ambient temperature of approx. 20 锟斤拷C (68 锟斤拷F) (room temperature).
Speed sensor setpoints, transmission input shaft
Speed sensor, transmission input shaft: Setpoint current > 3 --> < 20 mA
Diagnosis Information - PDK (Dual-Clutch Transmission)
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: P1824
- 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
- Electrical substitute value
- No gear pre-selection
- No R gear
- Transmission limp-home indication in instrument cluster control unit
P0174
P0174
Diagnosis information - Control unit DME (DFI)
Oxygen sensing adaptation Bank 2 : System too lean
Diagnostic conditions
- Short test
or
- Lambda control Active
- Lambda control taught
- Engine temperature > 60 锟斤拷C (锟斤拷F)
- Intake air temperature < 80 锟斤拷C (锟斤拷F)
- Engine running > 45 Second(s), at:
- Engine speed < 800 1/min
- then Trip with different operating conditions, at:
- Engine speed 1,060 rpm ... 2,490 rpm
Possible fault causes
- Exhaust system leaks (Engine --> Oxygen sensor in front of catalytic converter)
- Exhaust system Narrowed / Blocked
- Injection valve Faulty (Mechanical fault)
- Timing incorrectly set
- Fault in area Fuel high-pressure, Intake manifold pressure sensor, Throttle adjusting unit, Ambient pressure sensor, Intake air temperature
