2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 262



Damage to oxygen sensor.



- DO NOT use spray, grease, fluid or similar products on the oxygen sensor plug connections.



INFORMATION



- Do not interchange the oxygen sensor in front of the catalytic converter with the sensor behind the catalytic converter as this will result in



implausible fault entries.



- The plugs themselves are coded and cannot be interchanged.



Diagnostic conditions



- Perform all short tests in sequence (without Tank tightness).



or



- Engine running > 2 Minute(s), at:



- Engine at operating temperature



- All models: Oxygen sensor(s) ready for operation



- then steady driving > 10 Minute(s), at:



- Engine speed < 800 ... 3,200 1/min



- Mass air flow 120 ... 520 mg/stroke



- without Overrun phase(s)



Possible fault causes



- Short circuit to B+/ground/between lines or open circuit in the lines



- Different air flow to the oxygen sensor behind the catalytic converter, at:



- Catalytic converter damaged



- modified or nongenuine components



- Oxygen sensor in front of catalytic converter Bank 1 Faulty (aged)
