error code P0193

[sakirfp]

My 2004 ST with 235K miles just got a check light. The error code is P0193. The code says fuel rail pressure sensor. Circuit High Input.Is this just a simple sensor replacment or is there some other issue I need to worry about. Is this problem cause by fuel filter issues. This sport trac still has the orginal fuel filter.

at that high of milage the filter should have been replaced a few times now i would absolutely do that regaurdless as for the code that means low fuel pressure/flow so some culprits can be the filter, fuel pump, or possibly the sensor (never seen one yet be bad).

so start with the fuel filter, clear codes drive it for a while and if same code comes again check fuel pressure at the rail and confirm that with a chilton or haynes manual to check fuel pump pressure. if the pressures are low then your pump is bad. if pressures are good and in range then your sensor is bad

I have put over 1000 miles on my truck since I changed the fuel filter and reset the code...Knock on wood no problems..I am glad it was an easier fix.

I made to 241K miles and the error code came back. On occasion I get a slight hesitation. I think it is time for me to get a fuel pressure gauge connected up and check the fuel pressure. Now with my luck the fuel pump is going to need replaced...
