We have a  52 plateTraffic DCI 100 SL 27 which is intermittantly cutting out/flat and fault read is "P1882 fuel rail pressure sensor circuit"

Ecu is a G9t.

After speaking to Renault we have changed the pump pressure sensor and repaired a worn wire leading to it,(we were told by our supplier they have changed 10 this year and 20 last year!)

Only the fault is still occuring.Any help appreciated!

Regards

Hairy

There were a batch of faulty rail sensors stock-purged around that year - I had the same symptom of cutting-out when flat-out on a couple of vans.

Broken wires inside the loom are very common.  Bell the circuit through from the ECU, or measure the voltage on the three pins at idle.

[By pump pressure sensor, I take it you mean the £180 brass sensor in the fuel-rail?]

.

The sensor we changed was the pump one (Held on by three torx screws)

Have checked the wiring all seems fine and no added extras fitted to fuel system.

Is that brass rail sensor a more common faulty item?

That isn't a pressure sensor?  That's the regulator.

The rail pressure sensor, that your code refers to, is in the middle of the rail.

Check the voltage on all three pins, at idle and come back.
