Ford Ka Rail Pressure Sensor Issue

I can relate. I have a Ford Ka too, though a slightly different year. I experienced very similar symptoms to what you describe, specifically the check engine light and stalling. It certainly sounds like a fuel pressure sensor problem.

Thanks. Did your diagnostics also indicate a 'faulty rail pressure sensor signal,' or was the issue identified through other means?

Yes, the diagnostic error was exactly the same: faulty rail pressure sensor signal. I wouldn't recommend trying to fix it yourself if you don't have experience. Take it to a reliable workshop.

Thanks for the guidance. I consulted a mechanic, and the rail pressure sensor was indeed defective. The repair, including parts and labour, was 240€. The car is now working perfectly.
