Gilt für folgende Modelle:
4 ModelleS80 (2007–), V70 (2008–), XC70 (2008–), XC90 (2003–)
Was bedeutet der Fehlercode?
This code is event-based. The engine control module (ECM) monitors the exhaust with the lambda value and can determine it for each cylinder. Although the code is named cylinder 2, the deviation applies to the cylinders in bank 2, cylinders 4 to 6. The difference between them is too large to be compensated by individual cylinder lambda control. The cause is mechanical in the engine.
Mögliche Ursachen
- Mechanical causes in the engine
Was Sie tun können
- 1There is no fault-tracing for this code, since it only shows that the deviation cannot be compensated
- 2Read and note the fault code, and clear it if needed
- 3Have a workshop with diagnostic equipment examine the engine's mechanics for cylinders 4 to 6, for example the compression
Symptome, die Sie bemerken können1
- No noticeable symptoms for the driver
Was der Fehler beeinflussen kann1
- Individual cylinder lambda control is switched off
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
