What does this fault code mean?
The engine control module monitors the signal from the fuel pressure sensor and logs a fault when it is too high. The cause may be a signal wire that has come into contact with supply voltage, or a damaged sensor, pump or pressure control valve. The fault can limit engine torque.
Possible causes
- Signal wire shorted to supply voltage
- Damaged fuel pressure sensor
- Damaged fuel pump
- Damaged fuel pressure control valve
What you can do
- 1Read the fault code, clear it and road test to see whether it returns
- 2Check that the connector at the fuel pressure sensor is fully engaged and free from oxidation
- 3The fuel system runs at very high pressure and can cause injury. Have a workshop make pressure checks on the pump and pressure control valve
- 4Follow the signal wire from the sensor and look for chafing or pinched sections where it may have touched another wire
- 5If you have a diagnostic tool, check in live data whether fuel pressure follows the requested value with the engine running
- 6If the fault returns after a road test, have a workshop decide whether the sensor should be replaced
Symptoms you may notice2
- Car drives poorly and lacks power
- Text message and warning symbol in the display
What the fault can affect1
- Engine torque may be limited
General guidance for car owners. Diagnosis on the car can point to a different cause.
