P0193 Ford - 2004 sport trac

Question

Is it ok for check engine light to stay on after replacing the fuel filter? the previous code was P0193.

Answer 1

Hi there,

This code is for the fuel rail pressure sensor. This code isn't always a problem with the fuel filter, so if you still have this code you have another problem. Either the sensor has failed or the fuel pump is weak. The fuel pressure should be tested to see what it is.
