TPMS reset question
I did a search and didn't find an answer.
2012, stock 17" tires/wheels.
I did a DIY rotation so I did the reset. All went as expected.
But when I went to re-inflate the tires, I didn't get what I expected. My stock psi is 38. After the reset procedure, 3 tires were at 34ish and one was still sitting at 36-37.
I expected a much lower reading. Does this mean that with just a few (4psi) loss, the warning light will come on?
And why would 1 tire be different?
Thanks.

If your having just 1 tire/wheel show low then you may have a slow leak. Could be the tire, valve stem, bead on the wheel, etc.

From my understanding to reset " within the system" which tire is at which corner of the vehicle.
It's pretty simple, but having compressed air available is very handy to re-air each tire after the procedure. Basicly you get the truck in the relearn mode, let air out of each tire, in a specific order, until you get a beep of the horn, continue to all 4 tires, then done.

I've only had my truck for a week and have no other knowledge to all the displays. But, from what I've read in the owner's manual and have watched 2 different videos online, this TPMS reset/relearn procedure is a built in feature on all trim levels.

I was under the impression that a tire position re-learn is required only if you have a vehicle that runs different pressure in the front than in the rear, as is clearly specified at the beginning of the procedure. If you run the same pressure all around, no re-learn in necessary but it never hurts anything to do it.
My 2013 low pressure warning does not specify which tire is low so IMHO it doesn't care which sensor is where on the vehicle.
ETA: Copied from my Owner's Manual:
Tire Pressure Monitoring System Reset Procedure
Note: The tire pressure monitoring system reset procedure needs to be
performed after each tire rotation on vehicles that require different
recommended tire pressures in the front tires as compared to the rear
tires.

Yep, you're correct, thanks for catching that. This is a new to me vehicle that needed a tire rotation. After I did it, I was checking pressure and looked in the book about the TPMS, also did some online searching.
At least I've now done it and since I have air available, I'll probably do it when in doubt, and anytime there are changes to the tires.
Thanks for all the input.
