| Fault Code Description |
|---|
|
Diagnosis monitors oxygen sensor emissions control. The mixture is too rich and oxygen sensor emissions control makes it leaner. Fault monitoring conditions: The fault is detected whenever the mixture is made 30% leaner for longer than 30 seconds. |

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 vacuum sensor. - Intake air temperature sensor. - Camshaft sensor. - High-pressure fuel system. - Low pressure fuel system. - Check differentiated air intake system for tightness, while doing so check the following components as well: - Crankcase ventilation. - Oil cap. - Tank ventilation system. Check exhaust system for leak tightness. Replace injectors. |
