Arkana Hybrid Rail Pressure Sensor Fault

Hey! That sounds frustrating. I had a similar issue with my old Opel Insignia, but it was a diesel. Same symptoms: check engine light, stalling, and limp mode. The error code also pointed to the fuel pressure. A fuel rail is the component in the engine that distributes fuel to the injectors. It could be a faulty sensor, wiring issue, or even the fuel pump struggling. Have you checked the sensor's wiring for any damage?

Thanks for the response. I haven't checked the wiring yet. Where would I find the fuel pressure sensor, and what should I look for when checking the wiring?

The fuel pressure sensor is usually on the fuel rail itself. Trace the fuel lines from the fuel pump (near the fuel tank) to the engine, and you'll find the fuel rail. The sensor will be plugged into it. For the wiring, check for breaks, frays, or loose connections. If you're not comfortable poking around, take it to a workshop. Messing with the fuel system can be dangerous.

I'll schedule an appointment with a qualified technician. The technician confirmed the pressure sensor was defective and replaced it, and the problem is resolved. The repair cost 240€.
