Avantime Rail Pressure Sensor Issue

My 2002 Renault Avantime diesel has a check engine light, stalls at idle, and has reduced power after 195926 kilometers. The OBD II scanner shows a rail pressure sensor signal problem. I've checked the wiring, but could use guidance before replacing the sensor.

I had a similar issue with another car. Rail pressure sensors can cause that. Before replacing it, check the fuel filter. A clogged filter can cause pressure issues. Also, inspect fuel lines for kinks or blockages. What diagnostic tool are you using? Cheaper ones can be inaccurate.

I'm using a mid-range OBD II scanner that's worked well before. I replaced the fuel filter 10,000 kilometers ago, but I can check it again. Could a faulty fuel injector cause these symptoms, or is the rail pressure sensor the likely issue?

A faulty injector could theoretically contribute, but the error code points to the rail pressure sensor. Given the symptoms and code, the sensor is likely failing. I would recommend taking it to a local workshop to verify the sensor's function.

I replaced the rail pressure sensor after the workshop confirmed it was faulty. The repair cost 240€. Thanks for the help!
