What does this fault code mean?

The control module (ECM) checks fuel pressure on the low-pressure side using the fuel pressure sensor, which is built into the same unit as the fuel temperature sensor. The code is set when pressure varies less than the limit allows, meaning the signal is not moving as it should. The fault may be caused by internal damage in the sensor.

Possible causes

Internal fault in the fuel pressure sensor
Damaged fuel pressure sensor

What you can do

1Read and clear the code, then run the engine to see whether it returns
2Check the connector at the fuel pressure sensor for looseness, oxidation and damage
3If you have a diagnostic tool: read the fuel pressure in live data and check that the value changes when the engine is loaded
4If the fault remains after these checks, a workshop with diagnostic equipment should check the sensor

Symptoms you may notice3

The Check engine lamp lights up or behaves abnormally
Poor performance and lack of power, especially when the car is pulling away
The engine hesitates, surges or runs unevenly on acceleration, when slowing down or at steady speed

What the fault can affect1

The high-pressure fuel pump is switched off
