I just finished my build on my 2012 TRD and I have these two codes after about 30 miles driving. My build includes: DT long tube headers, URD Y-Pipe, 33's, OME suspension and Dakar leafs, Camburg UCA's, Front and Rear chunks from East Coast gear in 4.10 and Shrokworks front/rear bumpers + skids. I can't figure why any of this would throw a code. 1) Checked gas cap. 2) ABS wheel sensor??? 3) Rear diff sensor???
Any thoughts or experience greatly appreciated.
