Yes thats why i have this problem, my truck did not come with flex fuel, but the 5.3 that they transplanted I guess did and now i have the code because my fuel system doesnt have it.

Hey Guys I recently bought a 2001 Silverado with a 5.3 vortec swap. The truck originally came with the v6 and the previous owner did a 5.3 vortec swap. The truck has a code p0178, flexible fuel sensor circuit low input. My truck did not have flex fuel originally. Any help with solutions to get rid of the code to clear the check engine light so I can get it inspected. Can I go to a shop and have them disable the circuit so that it clears the lights, or do i need to install the sensor and have someone tune it for me? thank you in advance.
