Movano Rail Pressure Sensor Fault

I'm having trouble with my 2000 Renault Movano diesel. The check engine light is on, and the engine stalls sometimes when idling. I've also noticed a drop in power. The diagnostic scan says the rail pressure sensor signal is faulty. The van has 149287 km on it. Any ideas before I replace the sensor?

I had a similar issue with my Renault Movano, though it wasn't the same year. Your symptoms sound very familiar. Reduced power and stalling could be related to the fuel pressure. Does it happen all the time, or more when the engine is warm?

Thanks. It seems worse after the engine warms up. Does that sound like what you experienced? Can you give me more details?

Yes, that's exactly what happened to me. It got worse after the engine warmed up. Given the diagnostic code, a bad sensor is likely the cause. You could test the wiring, but the sensor is the usual suspect. I'd suggest getting a workshop to check it before you replace anything.

Thanks for the help. I took it to a workshop, and they confirmed the pressure sensor was faulty. The replacement cost 240€. The problem is fixed now.
