2010 Porsche Cayenne S (9PA) V8-4.8L A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 111
--> The system consists of the mechanical vacuum pump (on the vehicle engine), the leakage diagnosis pump, the intake pipe switchover valve
and, where appropriate, the exhaust flaps in the rear muffler
- Vacuum pump faulty
- Tank vent valve stuck in closed position
- Purge-air line between tank vent valve and carbon canister blocked
- Short circuit to B+/ground or open circuit in signal line
- Leakage diagnosis pump faulty
Affected contacts on the DFI control unit connector
Connector [A]:
- Contact 35
P2414
P2414
Diagnosis information - DME V8 DFI
Oxygen sensor ahead of catalytic converter bank X - in air
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
- Short drive > 10 seconds
- Lambda control active
- Vehicle not in overrun phase
Possible fault causes
- Specified oxygen sensor not installed in exhaust flow

P2626
Diagnosis information - DME V8 DFI
Oxygen sensor ahead of catalytic converter, bank 1 - pumping voltage line
CAUTION: Risk of damage to oxygen sensors if additives are used.
- Do not use contact spray on the oxygen sensor plug connections, as this will cause 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
- Exhaust temperature > 200 锟斤拷C (392 锟斤拷F)
