- LS XR 4155H
Our 2018 LS XR4155H started throwing several error codes yesterday. Through lots of research (thanks to this forum and some super old threads mostly) I've managed to figure out what two of the three error codes mean, but one has me completely stumped.
S173 | F31 —> DPF In temp sensor fault
S173 | F03 —> DPF In temp sensor high fault
S51 | F03 —> ?????????
My guess is that they're all related, especially since it keeps trying to regen every time I turn it on. RPMs aren't limited, so we're not having the limpness that others have experienced. I just cannot find that last error code and what it means. Anyone have any knowledge they can lend?
