Hva betyr feilkoden?
The control module (ECM) compares the signal levels from the four pressure sensors in the injectors with a lowest permitted value. The code is set when any signal is below that lowest value. Here the code is linked to the injector on cylinder 4, and the control module then uses the value from pressure sensor 1 instead.
Mulige årsaker
- Looseness or oxidation in the connections
- Faulty pressure sensor in the cylinder 4 injector
Hva du kan gjøre
- 1Read and clear the code, then start the engine to see whether it returns
- 2Check the connector to the injector on cylinder 4 for looseness and oxidation
- 3If you have a diagnostic tool: read the pressure from each injector in live data and see whether cylinder 4 is low compared with the others
- 4If the fault remains, a workshop with diagnostic equipment should check the pressure sensor in the injector on cylinder 4
Symptomer du kan merke3
- Uneven idle
- The engine may stall at idle or while driving
- The Check engine lamp lights up or behaves abnormally
Hva feilen kan påvirke1
- The value from pressure sensor 1 is used instead
