Clear ALL codes and test drive. Scan again after. Post the results
Btw, there is a short to the RR(passenger side rear) sensor, depending on what codes return, you will need to diagnose if it's wiring or the sensor. Visual inspection of the wiring looking for damage, or disconnect the connector to the RR sensor (inside wheel well liner on top of frame) to narrow down the source.
Same sight I had last year, attempting to pull the lr sensor. Take your time removing so nothing falls into the axle.
Hook and picks, sand paper, pb blaster, brake clean, and a drywall screw, to pull it out. Make sure you have a replacement on hand too, since the axle will be open when you remove.

flush with the axle housing. I had to chip away at it, scrape off a rust ridge that was preventing it from sliding out.
Then inserted a screw into it and popped it out.
