2005 Ford Taurus PO193

Question

Engine light shows this code, the light is intermitent and is off sometimes, but mostly on.
This is the correct code that comes up PO193. Been that way for 70,000 miles and car runs fine.

What is most common cause for this code, and what would be the part, or parts, needed and the average cost.

Answer 1

P0193 Fuel rail pressure circuit.

The fuel pressure sensor took place of the fuel pressure regulator,what it does is the ECM controls fuel demands by using varying voltage to the fuel pump,when the demands for fuel is needed the ECM increase voltage to the fuel pump in return the fuel pressure demands are met, here is the issue when this code appears,intermittent stalling, especially on highways,stalling when cruise control is used, The common cause of this code is bad idea. This is a common failure, so make it a hobby to replace
