Was bedeutet der Fehlercode?
The control module (ECM) compares the four pressure sensors in the injectors with each other against a highest permitted value. The code is set when any signal goes above the highest value. The fault is intermittent, meaning sporadic, and it may only be present some of the time.
Mögliche Ursachen
- Poor contact in the connections to the injectors
- The sensor in one of the injectors is faulty
Was Sie tun können
- 1Check the injector connectors for looseness and oxidation
- 2Clear the code and start the engine to see whether it returns
- 3If you have a diagnostic tool: read the pressure from each injector in live data and see whether any one is clearly high compared with the others
- 4If the fault remains, a workshop with diagnostic equipment should check the pressure sensor in the injector that differs
Symptome, die Sie bemerken können2
- Uneven idle
- The engine may stall at idle or while driving
Was der Fehler beeinflussen kann1
- The value from pressure sensor 4 is used instead
Allgemeine Hinweise für Fahrzeughalter. Die Diagnose am Fahrzeug kann eine andere Ursache zeigen.
