2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 273
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
- High fuel content in engine oil
- Exhaust system leaks (Engine --> Oxygen sensor in front of catalytic converter)
- 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
sensor, Speed sensor, Valve lift control, Camshaft adjustment
Fault setting condition(s)
- Opposed adaptation values in connection with misfires indicate that the timing is out of adjustment.
(negative deviation --> leaning)

Setpoint definitions
NOTE: The specified values and value ranges correspond to the OK state in each case.
Line test setpoints
Short circuit to B+:
- Setpoint voltage -0.5 V --> +0.5 V
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).
Temperature sensor setpoints
Temperature [锟斤拷C] Resistance [Ohm]
0 > 800 --> < 820
4 > 830 --> < 850
25 > 980 --> < 1000
37 > 1070 --> < 1090

Diagnosis information - PDK
Transmission oil temperature sensor, 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
- Short circuit in line between oil temperature sensor and PDK control unit
- Oil temperature sensor faulty
