TPMS sensors

[WVMountaineer]

Just bought a set of 2023 GMC take-off wheels and tires for my 2010 Chevy Silverado. The person I bought them from told me the TPMS sensors are a different frequency than my truck and may not read correctly, or at all. He was right, get the message upon start up and yellow light all the time, and no readings. I've read on Youtube how to change the sensors, doesn't seem like a big thing, but learning to the truck's computer seems like a task. Anyone ever do this?

You need the correct sensors.  Frequency on a 2010 should be 315mHz.

 

To learn the new sensors to the truck, its really easy and not a big task at all.  On a 2010 there are two methods.

 

Method one is the easiest one. 

 

Get a relearn tool (google EL-50448).  Once you have that, turn the ignition on, then take the key fob and press and hold both the lock and unlock buttons at the same time.  You will hear the horn beep twice and that is the sign you are in TPM learn mode. 

 

Starting with the LF wheel, take the relearn tool, put it up to the sidewall of the tire just below the valve stem and press the button.  You will hear the horn chirp, indicating the truck learned that wheel.  Proceed in clockwise order around the truck, so LF, RF, RR and finish with the LR.  Once you finish that LR sensor, you will hear it beep, then beep twice more.  The second *beep* *beep* means its learned the sensors. 

 

Method two is the air down/air up method. 

 

You put the truck into learn mode (turn the ignition on, then press and hold both the lock and unlock on the key fob at the same time).  Once in learn mode you will hear the horn beep twice.  Starting with the LF wheel, air down (or up) the tire.  Within a couple seconds you should hear the horn chirp, and once you do, that sensor is now learned.  Proceed in clockwise order around the truck, so LF, RF, RR and finish with the LR.  Once you finish that LR sensor, you will hear it beep, then beep twice more.  The second *beep* *beep* means its learned the sensors.

Here's a link to a very inexpensive relearn tool: GM Relearn Tool

 

I've been tempted to try it for $9.

After I posted this question, basically this afternoon, out of curiosity I stopped at the tire shop that I have dealt with for more than 40 years (so I trust them) and they checked the tires out and told me that there are actually NO sensors in the wheels. So sensors are definately needed. Great info I thank you guys so much. Next question.....the sensors that you see, Ebay, Amazon, etc. are they good to use? Is there a certain brand, type, etc.

I bought replacements from tpms.com and was very happy. They sell OE supplier parts and the customer service was very helpful. The cost for a set of four was about the same as one sensor at the tire shop.
