So I had a used engine installed in my 2015 Equinox 2.4 and it cost me a pretty penny lol, anyway I now have a code P0178 fuel composition sensor low voltage! I know what this is but I’m trying to figure out how to fix it! The shop used the wiring harness that came with the engine and I never had this code pre exploding engine. I want to know if anyone knows where the wires associated with the sensor are or have a wiring diagram for the system?
