Co oznacza ten kod błędu?
The ECM reads fuel pressure in the rail. If the pressure is too high, the code is set. Causes can be air in the fuel, a blocked return line, or a damaged sensor or valve.
Możliwe przyczyny
- The car has run with an empty tank
- Air in the fuel
- Blockage in the fuel return line
- Damaged fuel pressure sensor
- Damaged fuel pressure control valve
Co możesz zrobić
- 1Read and note the code, clear it and road test to see whether it returns
- 2Think about whether the car has recently been run on a low fuel level, since air can then enter the fuel system
- 3Look for fuel leaks in the fuel lines between the tank and the engine, since air in the fuel can come from there
- 4Check the plugs of the pressure sensor and the pressure control valve for contact resistance and oxidation
- 5If you have a diagnostic tool: activate the fuel pressure control valve and check that the fuel pressure in live data rises
- 6Have a workshop check the return line and the sensors, and replace any faulty parts
Objawy, które możesz zauważyć2
- Noise from the engine, especially at idle
- The engine jerks
