Ford V10 P0190 Code
My 2006 Fleetwood Storm with the Ford V10 is throwing a P0190 Code which my reader says is a Fuel Rail Pressure sensor on the "A Circuit" Does anyone know which side is the "A Circuit"

Has anyone ever changed out there had to change the Fuel Rail Pressure sensor?

How do you know there are two?
Typically there is only one pressure sensor for the fuel rails.
How do you know you need the sensor?
Have you done any other diagnostics other than pull the code?

There is one on each fuel rail. It is a v10

If there are two (no idea why ford would want to put twice the parts on when there is only one pump...)then compare the voltage return from both. That should show you which one is bad (if any).

You are right
I found schematics of the motor. You are right. Only one
