What does this fault code mean?
The engine control module (ECM) compares the fuel pressure on the low-pressure side with the highest allowed pressure while the engine is running. The fault code is set when the pressure is too far above the target value for a certain time. The causes can be air in the fuel system, leaks in the fuel lines, or a fault in the sensor, pump or pump control module.
Possible causes
- Clogged high-pressure pump
- Clogged check valve in the inlet pipe
- Air in the fuel system
- Leak in the fuel lines
- Damaged fuel pressure sensor
- Damaged fuel pump or fuel pump control module
What you can do
- 1Check the fuel lines for leaks
- 2Check the connectors at the fuel pressure sensor and the fuel pump for oxidation and loose contacts
- 3If you have a diagnostic tool: read the fuel pressure in live data with the engine running and see whether it is higher than the control module requests
- 4Have a workshop check the fuel pressure sensor with a gauge, and the fuel pump and its control module
- 5Have a workshop check the check valve in the inlet pipe and the high-pressure pump if the fault remains
Symptoms you may notice5
- The engine does not start, it only cranks
- The engine can stall at idle or while driving
- Uneven idle
- Poor performance and lack of power, especially when pulling away from a standstill
- Check engine lamp (MIL) lights up
What the fault can affect1
- The fuel pump is controlled using a calculated value instead of the measured one
