| Fault Code Description |
|---|
|
Diagnosis monitors oxygen sensor emissions control. The mixture is too rich and is made leaner through the oxygen sensor emissions control. Fault monitoring conditions: The fault is detected whenever the mixture must be made 30% leaner for longer than 30 seconds. |
| Fault Code Conditions | |
|---|---|
| General Conditions |
Temperature precondition: - None Time precondition: - None Other preconditions: - Engine running. - Tank ventilation system not active. Control unit voltage: 9 V to 16 V. |
| Terminal Condition |
Terminal 15 on |
| Terminal Condition |
PRD status: Driving |
| Terminal Condition |
PRD status: Testing-analysis-diagnosis |
| Driving Conditions |
Note: The designations of terminal status or PWF status apply according to the vehicle electrical system of the vehicle. |
| Fault Time Condition |
|---|
|
The fault code is entered if it exists for longer than 30 s |
| Service Plan |
|---|
|
If additional faults are entered for the following components, these must be processed first: - Oxygen sensor before catalytic converter - Hot film air mass meter - Intake pipe pressure sensor - Intake air temperature sensor - Camshaft sensor - High-pressure fuel system - Low-pressure fuel system - Valvetronic intake adjuster - VANOS adjustment unit - Voltage supply sensor system/actuator 5 V Check air intake system for tightness, checking the following components as well at the same time: - Crankcase ventilation - Oil cap - Tank ventilation system Check exhaust system for leak tightness. Rule out poor fuel grade. Renew injectors and then reset adaptations. |
| Fault Impact |

|
- Lack of power. - Rough engine running. |
