- Period since engine was started > 10 Second(s)
- Catalytic converter temperature 470 ... 800 锟斤拷C (锟斤拷F)
- 60 Second(s) Driving with slight acceleration at 25 ... 130 km/h
- loading Charcoal canister < 0.7
- Engine speed < 3,000 1/min
- Secondary air injection not active (only EU5)
- Lambda control Ahead of catalytic converter Active
- Lambda control Behind catalytic converter Active
- none of the following faults stored: Oxygen sensor(s) - Electrical fault, Intake manifold pressure sensor or Throttle adjusting unit
Possible fault causes
- If an oxygen sensor fault is entered:
- corresponding fault cause
- Remedy oxygen-sensor fault according to instructions
- then perform short test as described above
- Exhaust system leaks between Engine and Oxygen sensor behind catalytic converter --> above all at Mass air flow < 400 mg/stroke
- Oxygen sensor in front of catalytic converter and Behind catalytic converter Bank 1 interchanged
- Catalytic converter Bank 1 Faulty
P0431
P0431
Diagnosis information - Control unit DME (DFI)
Primary catalytic converter Bank 2 - Effect too low
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.
Diagnostic conditions
- Perform following short tests in sequence:
1. All models: Oxygen-sensor short tests
2. Short test Tank vent
3. Short test Fuel supply Partial load
4. Short test Fuel supply Idle speed
5. Short test Catalytic-converter conversion
or:
