- Code P0193 Fuel rail pressure sensor circuit high input. Tested fuel pressure found 28-29 psi (30psi is normal). Slightly low and fluctuating slightly. Found live data from Engine control module reading at 73psi from fuel pressure sensor. Found fuel pressure sensor faulty. Recommend replacing sensor and replacing fuel filter. Replaced sensor and filter and retested fuel pressure. Now reading a steady 30psi. Test drove several times and could not duplicate stalling concern.
- FUEL FILTER – Remove & Replace
- FUEL PRESSURE SENSOR – Remove & Replace – V6
