Safrane Fuel Pressure Sensor Issue

I experienced a similar issue with my Safrane, and I understand your frustration. The symptoms you describe – check engine light, stalling at idle, and reduced power – are indeed indicative of a potential problem with the fuel pressure sensor. When this sensor malfunctions, the engine control unit (ECU) receives inaccurate information about the fuel pressure in the rail. Consequently, the ECU may miscalculate the correct fuel-air mixture, leading to suboptimal engine performance and the issues you've outlined. Was there any specific diagnostic code that came up during the check?

Yes, the diagnostic code was P0190, which I think confirms it's the fuel rail pressure sensor. Did replacing the sensor fix problems in your case?

Affirmative, the P0190 code strongly suggests a fault within the fuel pressure sensor circuit. In my experience, replacing the sensor rectified the issues entirely. However, while it is plausible to attempt the replacement yourself, I would suggest you consult a workshop. The replacement requires attention to detail to prevent fuel leaks. Furthermore, the new sensor must be properly calibrated to ensure the engine runs optimally.

I took it to the workshop, and they confirmed the sensor was defective. They replaced it, and everything seems to be running smoothly now. The total repair cost was around 240€. Hopefully, this will help anyone else with a similar problem.
