2016 RAM 1500 Rear Parking Sensors

[MNiemczyk24]

Good afternoon folks!

So I've been fiddling with this issue for a few weeks now. My rear parking sensors aren't working, an error message keeps popping up on my instrument cluster to "Service ParkSense Sensors". Immediately after the message, the rear sensors shut off and won't turn back on even after hitting the button. I took all the sensors off the bumper, part# 1EW63WS2AA, and replaced them with sensors 1EW63TZZAA since they're supposedly interchangeable and they could be delivered the soonest. I install the new sensors, I get error codes B1295-92, B1296-92, B1297-92, and B1298-92. For the hell of it, I plug my old sensors back in and only receive B1295-11 (Didn't have the code reader prior to ordering the new sensors). Why would ALL of my new sensors error out when none of the circuits were bad, just one of the old sensors? Do they or the module have to be reprogrammed somehow? Are they actually not interchangeable? I need help before I end up ordering more sensors. Thank you!

Grab an ohm meter and ohm them all out if they're all close but one thats your culprit

I did that, sensor 8 showed 0 resistance across the ground and power compared to all the others which varied from 630-680, so I know the culprit sensor. Problem is it doesn't explain why the new sensors, the 1EW63TZZAA, test just fine across all the pins but error out on the parking system module. Are they not compatible?

I wonder if you googled crossover numbers if they'd be on the list for your truck? Or if it's year specific.

This is where my confusion comes from. My part was superseded by the new sensors I bought. Shouldn't it be just a simple plug and play? I'm half tempted to believe my parking module, P# 68141530AJ, needs to be updated or something to recognize the new sensors although I wouldn't know where to start there aside from going to the stealership.

Aaaaand I just called my FCA dealership up here, they've laid off their tech and are deciding today if they're even staying open or not. Crap. Next closest dealer is 2 hours away and I'm sure they're in a similar situation.

How did you figure out which sensors were which number... mine says that 8 and 11 are bad but i don't know which ones those are
