Clio rail pressure sensor fault

I have a 2022 Renault Clio with a gasoline engine. Recently, the check engine light illuminated, and the engine occasionally stalls at idle. I've also noticed reduced engine power. Diagnostics point to a faulty rail pressure sensor signal. Has anyone encountered this?

A faulty rail pressure sensor can indeed cause those symptoms. Is it a diesel engine? What mileage are we talking about? When was the fuel filter last changed, as that can sometimes affect fuel pressure readings? Definitely a tricky situation!

Thank you for your response. It's a gasoline engine. The car has 207797 km. The fuel filter was replaced approximately 30000 km ago. Could that still be a factor?

Okay, gasoline engine eliminates some common diesel fuel injection issues. 207797 km is getting up there. While 30000 km on the fuel filter should be fine, a faulty pressure sensor is the most probable culprit given the diagnostic code. You could try checking the wiring to the sensor, but honestly, sensor failure is common. A garage visit for a proper diagnosis seems wise.

Thank you for the advice. I appreciate the confirmation regarding the sensor. I've decided to replace the rail pressure sensor. Repair cost 240€. The issue is now resolved.
