Co oznacza ten kod błędu?
The control module (ECM) controls the fuel pressure in the fuel rail through the fuel pump and a pressure regulator valve, and checks whether the sensor signal is plausible. The code is set when the pressure does not change as expected or shows an offset while the engine is switched off. The signal is therefore judged to be implausible.
Możliwe przyczyny
- Poor contact or oxidation in the connections to the pressure regulator valve
- Clogged fuel filter
- Damaged fuel pressure regulator valve
- Damaged fuel pump
- Damaged fuel pressure sensor
Co możesz zrobić
- 1Check that the fuses are intact
- 2Read and clear the code, then start the engine to see whether it returns
- 3Check the connectors at the pressure regulator valve for oxidation and looseness
- 4If you have a diagnostic tool: read the fuel pressure in live data with the engine switched off and the ignition on, and see whether the value stays steady
- 5If the fault remains, a workshop should check the fuel pump and the fuel filter
Objawy, które możesz zauważyć2
- Message in the display together with a warning symbol
- Poor performance and lack of power
Na co może wpływać usterka1
- Engine torque may be limited
