i bought a 05 gmc envoy with the check engine light on. the codes are. p0410 p0014 and p0128. i checked the fuse box and im missing fuse number 56 as well as relay 55 and 49. i tried putting relay 43 in number 55 but its a loose fit. i read that some people have the number 56 fuse missing. could this be tripping this code?

Your P0410 code is related to your missing fuse 56 and relay 55. Chances are these items were intentionally removed due to some failure in the secondary air injection system. A common failure.

Relay 49 is for adjustable pedal.
