2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 706
Fault setting condition(s)
- The oxygen sensor signal deviates by a certain value from the control value (rich/lean mixture) within a certain time. (Abrupt large deviation)
P2197
P2197
Diagnosis information - Control unit DME (DFI)
Oxygen sensor in front of catalytic converter Bank 2 - Signal too lean / too rich
NOTE:
Separated plug connection = open reference-air duct.
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
- Engine running 3 Minute(s), at:
- without Overrun phase(s)
- All models: Oxygen sensor(s) ready for operation
- Lambda control Active
- Engine speed 640 ... 4,000 1/min
- Load 15 ... 70 %
- Catalytic converter temperature > 400 锟斤拷C (锟斤拷F)
- Mass air flow 10 ... 520 kg/h
- none of the following faults stored P2272, P2273, P0041
Possible fault causes
- Short circuit to B+/ground/between lines or open circuit in the lines
- Oxygen sensor in front of catalytic converter Bank 1 Faulty
Fault setting condition(s)
- The oxygen sensor signal deviates by a certain value from the control value (rich/lean mixture) within a certain time. (Abrupt large deviation)
