Surging after pro cal snap

[Darkspeed]

I decided to do the AEV pro cal snap tire size change and on the first drive I get a feeling like I’m slowing down then surging back up to speed. I also noticed a red line where my two rear tire pressures should be. And a low pressure alert. I put oem 433mhz transmitters in all wheels. Am I hitting a limp mode due to tire pressure or possibly pro cal snap related?

I thought the oem tpms sensors would wake on their own.

It serms to not want to let me go over 40 mph

Both front seem to register pressure and both back ones do not

Maybe remove the snap and see if that changes anything back to normal

I removed it per the instructions after the tire size change

Gotcha. Im unfamiliar with how it works.
Best i can offer is maybe hook it back up and be sure the tire size change stuck.

you could also let the truck pcm completely shut down and see if the problem persists after another restart.

or even completely disconnect the battery an reset it all ?‍

I changed the tire pressure in all 4 tires and the front two registered the pressure change on the screen. The back two are still not responding.

I’m starting to wonder if there is some interference with the rear two sensors

you could always try and rotate a rear tire, with a sensor that you know works, to the rear and see if that changes anything.

I put the oem tires/wheels back on and did a taco run and all for sensors responded and limp mode went away. Not very happy that a bad tpms seansor will limp a new gladiator.
