Question

2004 Mercury Sable V6 DOHC, how do u fix a p0193 ford engine code?

Answer 1

Hi there,

This code is for the fuel rail pressure sensor. It is possible that the fuel pump is causing low fuel pressure and setting the code, or that the pressure sensor itself is the problem. The fuel pressure must be tested to determine which it is. If the actual fuel pressure is reading fine, then the sensor must be replaced.

Answer 2
