Ford Focus ST P2455 Fault: High Pressure Reading Even with Sensor Unplugged

Model: Ford Focus ST Fault Code: P2455 Posted: 2020-11-06 14:05

Hi everyone, I'm experiencing a P2455 fault on my Ford Focus ST. In live data, the high-pressure reading shows 88.6 kPa even when the pressure sensor is completely unplugged. This is highly unusual and suggests either a wiring issue or an internal malfunction in the system. I'd appreciate any insights or troubleshooting steps from experienced users who have encountered this specific fault code on their Ford Focus ST models.
