Question

I have a 2005 Ford Focus with engine code P0193, what is the meaning?

Answer 1

P0193 is fuel rail pressure,here how it works and why you have the code,instead of running the fuel pump at a constant speed with a return line on it, they use a fuel rail pressure sensor, when the fuel demands are needed more voltage is applied to the fuel pump,thus more fuel.There is no need to check fuel pressure when this code appears,you should on ly do it,when this code is not on.,your solution is to replace the fuel rail pressure sensor

Answer 2
