2008 Ford Escape P0193 Fuel Rail Pressure Sensor Code: Causes and DIY Fix for Retired Owners

I recently encountered a recurring P0193 fault code on my 2008 Ford Escape with a 4-cylinder, 2.3L engine and 5-speed manual transmission. I replaced the fuel rail pressure sensor as recommended, cleared the code, and drove the vehicle—however, the P0193 code returned immediately. The car is a front-wheel-drive model with no history of major mechanical issues. As a retired individual on a limited income, I'm trying to diagnose and fix this issue myself without costly repairs. The P0193 code indicates a problem with the fuel rail pressure sensor. Possible causes include: - Short circuit in the FRP signal to power - Open circuit in the FRP sensor wiring - Damaged or faulty fuel rail pressure sensor itself I'm seeking advice from others who have faced this issue—especially those who successfully resolved it through DIY methods. Any insights into diagnostic steps, wiring checks, or potential sensor replacement tips would be greatly appreciated.
