P0193 Lincoln -Fuel Rail Pressure High

Question

I have a 2004 Lincoln LS, I've had it for two years and the code has shown up 4x. It has had the pressure sensor replaced 3x and a new fuel pump. Yet less than a year since the last repair, the code is re-appearing, is it a chronic issues without a resolution? Debating on whether it is time to trade car in or keep patching it.

Anyone else have a similar experience and how did you solve it?

Thanks

Frustrated in Texas.

P0193 Fuel rail pressure sensor circuit high input

If this was replaced and this is a re-appearing condition the harness connection needs to be checked, this is done by doing a wiggle test of the FRP connection,with the code cleared and test to see if it codes up during the wiggle  test.  and the voltage to the FRP sensor needs to be check, Another cause for this to re appear is the PCM you may need a PCM
