2010 Porsche Cayenne S (9PA) V8-4.8L A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 82
NOTE: The fault is detected if the adaptation limit (4%) has been exceeded.
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
- All 4 oxygen sensors ready for operation
- Lambda control active
- Engine speed 640 ... 4,000 rpm
- Engine load 15 .. 70%
- Catalytic converter temperature > 400 锟斤拷C (752 锟斤拷F)
- Mass air flow 9.4 ... 528 kg/h
- Engine running > 2 minutes
- No fault P2272, P2273 or P0041 entered
Possible fault causes
- Leak in exhaust system between the two oxygen sensors on bank 2
- Tank vent stuck in open position
- Secondary air before intake valve
- Fault in intake camshaft
- Valve lift error
- Mechanical fault in valve drive
- Oxygen sensor ahead of catalytic converter, bank 2 faulty (old)
