v10 codep0191

stoped at auto zone and they ran a check on the E350 ,code was p0191

engine runs good BUT I found 2 metal vaccum pipes that are joined

to gether with a rubber hose near the fuel filter, the rubber hose

was burned real bad,replaced the vaccum hose with fuel line hose,

the hose receives a lot of heat from the left exh pipe,,I also have changed the fuel filter now I need a test run 200mi plus
  • The code P0191 has to do with the fuel rail pressure sensor circuit. Read this link for possible causes. Also google p0191 OBD II for more answers
