I had some 20s put on my 07 Tahoe. now, I have a check tire pressure message showing. Someone said something about the tire sensors.. Can you not switch tire sensors from tire to tire? Does anyone know the deal on this?? Thanks!

Did you perform the relearn process spelled out in the owner's manual?

CoachQYR

No, I didn't.. I'll try that.. Thanks..

I tried to relearn the tire positions and that didn't work..

Maybe ZX/Dave has a suggestion.

the question is..are you 100% sure that the sensors were moved to your new 20s? the "add air or lose air" method in the manual seems to be full proof assuming you have the sensors in place. i actually have had my 24s (with sensors in..my 4x4 17s dont have sensors) in the cargo area of the truck..and i had 1 or 2 tires detected by the DIC (info center),

Do the sensor stems look metallic with retaining nutlike this (early 2007 model year Tahoe sensors),




or are they plain rubber looking stems like these (late 2007 model year Tahoe sensors):



Sounds like the tire shop just moved your sensors from one set of wheels to another, but perhaps new sensors were bought for the new wheels, and perhaps one type (early?) was swapped for another (late?)? If so, I'm not sure the two (early vs late 2007 MY sensor styles) are interchangeable. ZX/Dave?

Perhapswrong new sensors (still with metallic stems) were bought, but with P/N for another Chevy application? Either this or the tire shop destroyed a sensor during the mounting process.

Alsoanymore,it will be hard to visiblydiscern late MY rubber stemmed GM TPMS sensors from plain old run of the mill non-TPMS rubber valve stems, since the two look nearly identical anymore...

Take it back to the tire/shop that installed your 20's first and see if they have the capability todiagnose/check TPMS system function usinga TPMS test/reset tool like this one...



Worst case, your Chevy dealer will have this "Kent-Moore J-46079" tool (needs to be updated w/ v.3.3 or later software), and they can troubleshoot your TPMS system for you...to determine if it's a TPMS sensor or TPMS receiver system problem...

For information: I was able to confirm yesterday evening that the J-46079 TPMS diagnostic tool withversion 3.3 software can excite/interrogate the new rubber stemmed sensors (I tried my J-46079 tool w/ v.3.3 sw on a new late 2007 Avalance equipped with these new sensors and it was able to excite & interrogate sensor ID # and PSI)...
