Hi i'm new to the Fiat forum.
Has anyone had fuel pump pressure regulator faults on a 1.9 multi jet?
And if so what are they and how much does it cost for a new regulator?
My Doblo just started cutting out when driving and engine warning light came on. Turn ignition off and on and warning light goes out and engine runs normally. Fault codes stored for fuel pressure regulator faults.

Just a guess, but it could be in need of a new regulator or more likely, a clean up of contacts.

If it resets after switching off and on, a sensor needs a kicking in my humble opinion.

Usually, an ecu will act strange if a sensor tells lies

Thanks
Sorted it now, new fuel filter and fuel pressure sensor did the trick.

Was the fuel pressure sensor on the HP fuel pump?
Was it an easy fix and if you don't mind me asking, what sort of dollar was the pressure senor.
