So yeah....just an update for everyone.
I purchased the set in the link below after reading some mixed reviews - some said Chinese junk some said it worked with the most relevant review being a dude with a Tacoma plus vid and pics. Was fairly pessimistic initially till I received the package on Saturday. Obviously cheaper quality than OEM but wasn't as cheap as I would've imagine originally with the only complaint being the outta ring quality. OEM outer ring obviously is abs plastic with flex whereas this one was hard and brittle plastic.

Anyway so i swapped out the bad sensor and wtf.....it fucking worked. Like for real fucking worked!!! System error went away and I also test it out backup into my wife etc.. and yeah it picked her plump body up no probs!!! Pleasantly surprised to be honest. Keep and use the OEM outer ring if you can is my advice but sadly, i wrecked mine previously. So the real test is long term....we'll see after.
Thanks to everyone for their help btw!!!
