Question

I have a 2005 Ford Focus 2.0L with P0193 code, what the code means?

Answer 1

Hi there,

Fuel Rail Pressure Sensor Circuit High Input. ... indicates that the signal from the Fuel Rail Pressure Sensor and/or its circuit is too high, indicating a fuel pressure condition that is abnormally high.

This is normally a result of a bad fuel pressure sensor or fuel pressure regulator. It can also be caused by a leak in the vacuum line for the fuel pressure regulator. On this model the regulator is part of the FPM(fuel pump module)
