2010 Porsche Cayenne S (9PA) V8-4.8L A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 92
NOTE: Do not use contact spray on the oxygen sensor's plug connections as this will result in irreparable damage to the lines (blockage of
reference air duct).
NOTE: Do not interchange the oxygen sensor ahead of catalytic converter with the sensor behind the catalytic converter as this will result in
implausible fault entries.
Diagnostic conditions
- Engine at operating temperature
- then drive for 2 minutes (incl. 1 overrun phase)
- Then engine idling > 30 seconds
Possible fault causes
- Open circuit in Nernst voltage
- Oxygen sensor faulty
Affected contacts on the DME control unit connector
Connector [A]:
- Contact 12
Affected contacts on oxygen sensor connector ahead of catalytic converter, bank 1:
- Contact 6
P2247
P2247
Diagnosis information - DME V8 DFI
Oxygen sensor ahead of catalytic converter, bank 2 - open circuit
NOTE: Do not use contact spray on the oxygen sensor's plug connections as this will result in irreparable damage to the lines (blockage of
reference air duct).
NOTE: Do not interchange the oxygen sensor ahead of catalytic converter with the sensor behind the catalytic converter as this will result in

P2270
P2270
Diagnosis information - DME V8 DFI
Oxygen sensor downstream, bank 1 - signal too lean / rich
NOTE:
This fault is detected if the oxygen sensor signal upstream deviates by a certain value from the control value (rich/lean mixture) within a certain time.
Diagnosis is initiated by fault detection in the mixture control.
Diagnostic conditions
- II Relatively long drive in various operating states
- Diagnoses >Electrical fault of oxygen sensor downstream [or] Lambda correction downstream< must have taken place
