A question here.

I put my winter tires and wheels fromy 2019 Silverado 2500HD onto my new 2021 Silverado 3500HD  and the truck will not read the TPMS sensors. The tire shop said the dealer needs to reprogram the sensors to the new truck. Took it to the dealer and they say that this cannot be done even though the TPMS part numbers are identical between the years and that I need to buy new sensors for the new truck. Any help would be appreciated as this makes no srnse to me! Thanks in advance.

The MHZ (sensor frequency) might be different from the old model to the new model? IF they are different then you cannot use them. You would have to get new sensors.

Like I said, they are the SAME PART NUMBER, both 433mhz, no difference.

Ya, If they were programed to a different MHZ, you cannot program them to a different one after. What is the part number for the sensor. 

 

If they were programmed to 315MHZ then they cannot be changed to 433MHZ (and vice versa) and a new set of sensors will need to be ordered.

13528563 part number for both trucks. Both 433mhz. FACTORY sensors from the 2019, not some cheap aftermarket chinese sensors. Sensor tool reads them fine, but will not register to the 2021 truck. Dealer just says I need to buy new ones, no other explanation.

That's weird. i would run it down to Americas tire(discount tire and see if they can do it. assuming the tire shop wasn't Americas tire/discount tire). Keep you old set of tire with sensors at home( away form the vehicle).

 

They will do it for free and it will take a few mins.

They were the original tire shop that said only the dealer could re-register the sensors.

Did they break down the bead on the 2019 wheels to verify the sensor # and frequency?  

 

Do you have the VIN from your 2019 still?

You can buy a cheap relearn tool for $10 that will do both 315 and 433MHZ. You have to put the truck into learn mode and then use the tool at each sensor and it will honk the horn when it is learned. I've done this on my 2021 and with the 315mhz sensors numerous times on my 2008 Avalanche.

If the dealer and a tire shop cannot do it with professional gear, how is a cheap tool going to help? LOL

I've dealt with enough idiots that are "professionals" and can't fix crap that I've been able to fix myself. It's not rocket science to pair sensors if you follow the correct procedure and the sensors are indeed the correct matching frequency.

Yupp -- and newdude is trying to get the OP to verify that the part number/frequency for both sets of sensors.

Some part listings show multiple part numbers for the years in question. 

Verifying what they are may help determine the solution -- and determine if the dealer is correct that new sensors are needed.

 

No matter what tool is available, if the frequency of the sensors does not match the frequency of the vehicle they will not be able to be paired.

 

Of course, this is why many tire shops use dual frequency sensors.

Slightly higher sensor cost, but then it doesn't matter what the vehicle frequency is.  Great convenience to the tire shop.

I pulled 6 random 19 2500 vins online and checked them, all the trucks had 13540604. 

 

If your truck actually does have 13528563, where are the wheels you took off? if they are close might be throwing off the program.

    • I went to order some PF63 oil filters from an on line GM parts source, and the blue PF63 oil filters seem to be getting phased out. They show the new part number as 19363567, which is a black colored AC Delco Silver product apparently marked PF63A. Some sites show a part number 12693541, which is a black colored AC Delco Ultragard Gold filter marked UPF63R.    I assume the UPF63R is the better one, but I’d be happy if I could just get blue PF63 filters I’ve been using.    Can anyone explain what is going on with the filter part number changes and any actual design changes?  Any other advice on buying OEM filters right now?  Thanks 
    • thanks for coming back and posting what the fix turned out to be.
    • Only TAN I have for the product was at 5K in service miles and it was 2.71
    • If anyone lands here looking for an update - the problem wasnt with the hose, the clamp, etc... I purchased a metal Thermostat housing that just must not of been made to spec. It just wouldn't plug up the hose.. Went back to a plastic cheap housing - leak fixed. Some plumbers tape carefully placed in tandem with a clamp likely would've gotten the job done.   Best,
    • For anyone following, this is what I have deduced from this forum - and my very specific niche case. Please do let me know if you see me going in the wrong direction here. For context, I have a 16 sierra 1500 w/t. Has TC and Cargo light switches. Removed the switch to find the X1 and X2 of the S48A connection populated with wires (x1 10-14, and x2 1-5).   Took photos of the X61A-X5 to find the wires from S48A-X1 land here at their respective pins (10, 11, 17, 23 on the X5). Was hopeful that this means my X51A fuse box has the appropriate pins... No cigar. So now I will be routing wires from the rear of the X61A-X1 to the engine bay and to their respective negative relay triggers. Please see to the diagram. If any has insight as to where the S48A-X2 pins 4 and 5 land that would be awesome.   Will be attempting this sometime shortly and will likely make a youtube video out of it.   Note: please disregard fuse sizes. Main fuse will likely be 25A, all mini bus fuses will likely be 10-15A.   Here is my parts list: GM 84347199 - TC, Cargo Light, Exhaust Brake (useless to me unless I find a means to reconfigure), Aux 1 - 4. 12V 6 Way Pre-Wired Fuse Relay Box Kit with 4 x 40A 4-Pin Relays (link below - some mods required to make negative trigger)            https://www.amazon.ca/dp/B0F4KCS43B?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 Various wire sizes (12 AWG - red and black, 14 AWG, 16 AWG multi-colored bundle) Wire termination leads for X61A-X1 (unknown at this time) Crimp connectors/Soldering Gun Heat Shrink Split Wire Loom To be continued...    Cheers
