Citan engine trouble rail pressure sensor signal

I had a similar problem with my vehicle. Engine stalling and diminished power indicate a potential malfunction in the fuel rail pressure sensor circuit. The ECU relies on the sensor signal to maintain optimal fuel delivery, and any issue can cause the problems you've observed. Have you checked the wiring harness and connector to the sensor for damage or corrosion? Also, what specific error code did the OBD reader display?

I had a quick look at the wiring, didn't see anything obvious, but I'm not really sure what I'm looking for. The error code was something like P0191, I think. Does that sound right? Is it worth trying to clean the sensor, or should I just replace it?

That error code is consistent with a rail pressure sensor issue. While cleaning the sensor might help temporarily, I'd advise replacing it, especially given your vehicle's mileage. A bad sensor can cause erratic engine behavior. To avoid further issues, especially if the problem is deeper in the fuel injection system, I'd recommend having a qualified technician diagnose and repair it. The repair cost me about 240€ at the shop.

Okay, thanks for the advice! Sounds like it's best left to the professionals. I'll book it into the workshop and get them to replace the sensor. Hopefully, that'll sort it out. I just wanted to be sure before I spent money on it! I got the sensor replaced. It runs great now! Thanks again for pointing me in the right direction.
