O2 sensor codes (P0032 and P0052)

21 Tacoma 3.5 V6.
Did some work on it (installed new steering rack and some other unrelated work).
Put the battery back in, started and now have a CEL and reading as P0032 and P0052.
No wires were touched, truck only has 17500 on it.
Any thoughts on what may have occurred?

Those codes are for high current.
Are you sure you didn’t pinch any wires?

 

Very sure. I have been

Figured it out.
There is a ground wire on the power steering pump (which I did not reattach when upgrading the pump). I attached it to ground and light went away.
