XR4150 CODES S173 F03 AND S173 F13

[mred2]

I am getting these two codes. I think temp sensors, but which one. I think it has 3. Runs fine, but will not regen. I hate to haul it 60 miles to dealer.

S173 F03 is P242D should have solid amber light on & indicate DPF In temp sensor HI fault
S173 F31 is P242A should have solid amber light on & indicate DPF In temp sensor fault

Can't find S173 F13

I am sure you are right and it is F31. The DTF HAS 3 temp sensors. I will start by checking connections. I looked for mice, none found.
THANKS
