Master fuel pressure sensor issue

My 2010 Renault Master diesel is throwing a fit. Check engine light's on, idles rough, stalls sometimes, and jerks when accelerating. Fuel pressure sensor, yeah? Anyone else had this? I've checked the obvious – fuel filter's new, but could a dodgy cable or plug really cause all this?

Sounds familiar! I've got a Master too, and had similar grief. Engine stalling, terrible fuel economy... Was pulling my hair out! Did you check the fuel pump relay? That was my first thought, but fuel pump itself could be the culprit too.

Fuel pump relay, right, I'll check that. But was your issue identical - rough idle and jerking too? And did the computer throw the 'fuel pressure sensor' code?

Yeah, pretty much a carbon copy. And yeah, same error code. I'd say, bite the bullet and take it to a workshop. They'll diagnose it properly. Could save you a lot of guesswork and wasted cash on parts.

Workshop it was. Turns out you were spot on - fuel pressure sensor issue. A defective cable/plug connection was the reason for it. 95€ later and she's purring like a kitten again. Appreciate the advice!
