2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 698
Diagnosis information - Control unit DME (DFI)
Lambda correction Behind catalytic converter Bank 2 - Control limit exceeded (too lean)
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
- Perform all short tests in sequence (without Tank tightness).
or
- steady driving > 20 Minute(s), at:
- approx. 80 km/h
- in the highest gear
- Lambda control (Behind catalytic converter) Active
