Do I need to re-learn TPMS after tire rotation?

[Interleukin6]

This was the first time I did tire rotation (everything is stock) for my 2022 1500 LTD LT. Do I have to re-learn TPMS? I have a tool from Amazon but my truck has not thrown any warning. Still, do I have to do it? Thank you.

Only if you actually want know the true location of the tire(s) after being moved

Sorry, I don’t get it. What does the true location of the tires mean? If I don’t know of it (no re-learn), will this have a negative effect on the truck?

There will be no negative effect on the truck if you do not relearn the tire positions.

 

If a tire goes low pressure and you get a warning, the truck may not actually tell you the correct tire position that is low because it did not learn the new location after you rotated them. So be prepared to be confused about which tire exactly is low.

 

Other than that, no harm

When you go through the relearn the vehicle will generally start at the left front and then work counterclockwise. You will go wheel by wheel and wake up the sensor in the  position that the vehicle requests. The sensors will then reflect the position you input.

Ah~ Now I got it. Thank you so much for explaining. I am going to re-learn!!!

It won't give you a warning that the sensors were moved.

If you get a low pressure situation, it will still give a low warning, but will be indicating the wrong location.

The sensors will still give a reading -- but the truck won't know the correct location of each the sensor unless you go through the relearn process. 

 

eg -- if you moved both rears to the front, and don't re-learn the positions, then the display will show the pressures of the tires (that are now on the front) as being on the rear.

You can verify this by pumping up a pair of tires by say 5psi and seeing how the higher pressure shows up on the display.

As a side note, it is one of my pet peeves when I get my tires rotated and the shop doesn’t relearn the sensors.  I’m guessing it saves them some time not to do it and most people will never notice but it really ticks me off and I always notice it because I keep my tire pressure pretty tight to the recommended levels and weather changes will have me adjusting the air in my tires.  Now, when I get my tires rotated, I make them aware I’ll be checking it.  At first, I just stopped going to those places, but I ran out of shops to get the work done.

So as not to get disappointed, I do the tire position relearn myself.  This also allows me to verify that the tires were moved to the correct positions.  I use my scan tool to initiate the relearn and look at the sensor serial numbers.

 

@Interleukin6 If you got a low tire warning light and put air in the LF tire when it was really in the RR position, then you overfilled a good tire and still need air in the other one.  Wasted time and put yourself or wife and kids at risk.

on 2022 and newer you dont need the tool. put your truck in relearn and drive it for 10 to 15 miles and the sensors relearn the new position

Do you have a link to the procedure to put the truck in relearn mode without a tool?

I recently had my tires rotated. I run the front at 60 psi and the rear at 80 psi.  When I got in the truck I looked on the screen at the tire pressures and everything looked great...60 front, 80 rear.  After driving it, it just didn't feel right, so I checked the pressures with a gauge.  My fronts were at 80psi and the rears at 60psi.  So the shop had not only not done a relearn, they had not not redone the pressure.  The truck still thought the 80's were on the back and the 60's were on the front.

2022 refresh and newer.  2022 LTD so same as a 2021 has the manual learn sensors still.

You just drive it.  2023 once you rotate them, it should sync them almost immediately.  If it doesn't, it just needs to sit off for 20 minutes.  When you drive it again it will pick them up.

80 PSI?  Wow.  I bet that's a rough ride!
