What it means

The computer monitors fuel pressure in the system. The pressure is wrong, the regulator isn't working, or the pressure sensor reading isn't plausible. The signal drops out now and then. The most common cause is a loose connector or a chafed wire.

What you may notice

Engine light on
Hard starting
Less power or limp mode
The engine may stall

What could be wrong

1Connector loose, damp or corroded
2Wire broken or chafed
3Faulty sensor or regulator
4Engine computer fault (rare)

Repair difficulty: Moderate

What you can check yourself

First look at the connector and wiring: anything loose, melted or green with corrosion? If the fuel filter hasn't been changed for a long time, start there. Check for any fuel leak or smell. Best left to a workshop. It needs a diagnostic tool and experience.

How we fix it

We read the fault data on the diagnostic tool and check whether the fault is constant
We measure the circuit's supply, ground and signal
We repair the wire or replace the connector
If the wiring is fine, we replace the sensor or regulator
