Tire Pressure Monitoring Sensor

[Kiernanjp]

I have a 2004 Tahoe LS and need to replace the TPMS on the passenger side front wheel. Can anyone explain how to do this?

It's the valve stem on that rim. If you don't know how to swap out valve stems, I would let a shop do it. Most will replace for free if you buy it from them

Forgive my ignorance, but are you saying the TPMS is inside the tire itself? I just had the tires replaced and the shop told me they couldnt get the one in question to reset. If it is inside the tire/rim, how does it communicate with the DIC?

I have to do it every time I rotate the tires. Simple and in the Owners Manual...a matter of lowering the tire pressure one-by-one, horn beeps...rather convoluted, but it's all in the book.

1. Set the Parking brake.
2. Turn the ignition switch to RUN with the engine off.
3. Turn the exterior lamp switch from “Off” to “On”
four times within 3 seconds. A double horn chirp
will sound and the TPM low tire warning light
will begin to flash. The double horn chirp and
flashing TPM warning light indicate that the TPM
matching process has started. The TPM warning
light should continue flashing throughout the
matching procedure. The SERVICE TIRE
MONITOR message will be displayed on the Driver
Information Center (DIC).
4. Start with the left (driver’s side) front tire.
5. Remove the valve cap from the valve cap stem.
Activate the TPM sensor by increasing or
decreasing the tire’s air pressure for 10 seconds,
then stop and listen for a single horn chirp.
The single horn chirp should sound within
15 seconds, confirming that the sensor identification
code has been matched to this tire and wheel
position. If you do not hear the confirming single
horn chirp, you will need to start over with step
number one. To let air-pressure out of a tire you can
use the pointy end of the valve cap, a pencil-style
air pressure gage or a key.
6. Proceed to the right (passenger’s side) front tire,
and repeat the procedure in Step 5.
7. Proceed to the right (passenger’s side) rear tire,
and repeat the procedure in Step 5.
8. Proceed to the left (driver’s side) rear tire, and
repeat the procedure in Step 5.
9. After hearing the confirming horn chirp for the left
rear tire, check to see if the TPM warning light is
still flashing. If yes, turn the ignition switch to OFF.
10. Set all four tires to the recommended air pressure
level as indicated on the Tire and Loading
Information label.
11. Put the valve caps back on the valve stems

Did it work before you had the tires replaced? If you can`t get it to work with the reset i`d put the blame on the shop that changed the tires.

When removing the old tires it`s easy to break a monitor if you don`t know what you`re doing.

I have tried the reset directions in the manual to no avail. I had the issue before I replaced the rear tires, but the tire in question is the front passenger. So basically the TPMS is part of the valve stem inside that rim.. I guess I'll have to go that route.. My wife work's at O'Reilly's so we get 30% off.. Thanks for all the help!

They are 40-50$ on amazon. Get the right part number. Later trucks TPMS changed after our vintage. I have 2015 wheels and tires on my 04 and sensors do not work.

And yes, they sit inside the rim. It is like an inverted T with top of the T inside the rim/tire and the bottom of the T is your valve stem. PITA to replace. But if you buy your own, I had the Wallmart mech say he would replace for about 5-10$ each tire. I think he had said $20 for all tires. Never did it though.
