TMPS Sensor Help

[Rally_18]

Just bought a set of wheels and tires and im looking to order a set of sensors for them. It looks like theres two different one 433MHz and 315MHz. How can i find out which one my truck takes? 2018 Silverado Custom 4x4 Factory Black Aluminum 20's with the steel 17" Spare. Thanks

The dealer should be able to tell you or maybe the tire store where you get your tires mounted.

I believe only the Corvette and Camaro uses the 433hz sensors. At least up to about 2015.

Oop's, a little more research shows 315 and 433 for 2017 and 2018.

The HD trucks use the 433 and the non HDs use 315s. At least from what I've gathered during my TPMS sensor fiasco

Is there any code inside the glove box or anything that would help identify which is which. I'm wanting to leave the sensors in my factory wheels and put a new set in my new wheels an tires. The few tire shops I've talked to back here want to charge me two take the sensors out put valve stems in and balance them then mount and balance the new ones so I'd be paying 20-25 per wheels x8 so I figure the 100 I would save would almost buy me a spare set of sensors.

Call GM. Give them your VIN and they should be able to tell you.

I would be willing to bet it's the 315hz. I would just order those and relearn them to your truck before you put them in the wheels to make sure they all work anyways

I would reach out to GM and have them give you a free build sheet unless you have the sheet that shows all the options from the factory. On my 14 it shows an option for 315mhz for my tpms system.

Good idea, email them at [email protected] give them your VIN and they will send you a build sheet document free. Mine are the 315mhz:

XL7 - FREQUENCY RATING 315 MHz

Double check your RPO code list in the glovebox. If you see a code for XL7, you have a 315MHz system, if you see a code for XL8 you have a 433MHz system.
