Installation of Sensors

With the tire removed, clean the valve stem hole with a Lint free cloth to ensure there is nothing that will compromise the seal between the valve stem the wheel.

Also clean the back side of the wheel.

Check the valve stem seal for any cracks or imperfections. Also clean the seal.

Sequence of sensor installation.

Insert the valve stem into the wheel from the backside (Inside). Make sure you have room for the wrench to clear the wheel.

From the face of the wheel, remove the valve stem cap and install the washer included with the sensor over the valve stem.

Install the included Valve Stem nut and hand tighten.

With your open end wrench hold the back side of the sensor still. Use a deep socket and tighten the valve stem nut to your sensors required torque. Notice the seal will expand against the back side of the wheel (Doorman Torque 35 lb-in AC Delco: 62 lb in). Be careful not to scratch the face of your wheel with the socket.

Hand tighten the valve stem cap when complete.

Place the screw through the slit in the sensor and start to thread the screw into the valve stem. Make sure the sensor is as flush to the wheel as it can be. You do not want it to stick up from the wheel

Note: Not all TPMS will have this fastener, ACdelco Sensor and valve stem are one unit.

Tighten the sensor to the required torque. (Doorman is 35lb-in)

TPMS Sensor Matching Process

Each TPMS sensor has a unique identification code. Any time you replace one or more of the TPMS sensors or rotate your vehicle’s tires, the identification codes need to be matched to the new tire/wheel position.

The sensors are matched to the tire/wheel positions in the following order: driver side front tire, passenger side front tire, passenger side rear tire, and driver side rear tire using a TPMS diagnostic tool. See your dealer/retailer for service.

The TPMS sensors can also be matched to each tire/wheel position by increasing or decreasing the tire’s air pressure. If increasing the tire’s air pressure, do not exceed the maximum inflation pressure indicated on the tire’s sidewall. To let air-pressure out of a tire you can use the pointed end of the valve cap, a pencil-style air pressure gage, or a key.

You have one minute to match the first tire/wheel position, and five minutes overall, to match all four tire/wheel positions. If it takes longer than one minute, to match the first tire and wheel, or more than five minutes to match all four tire and wheel positions, the matching process stops and you need to start over.

The TPMS sensor matching procedure is outlined below:

1. Set the parking brake.
   
   
2. Turn the ignition switch to ON/RUN with the engine off.
   
   
3. Turn the exterior lamp switch from AUTO to OFF four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light starts flashing. The double horn chirp and flashing TPMS warning light indicates the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The LOW TIRE message displays on the Driver Information Center (DIC).
   
   
4. Start with the driver side front tire.
   
   
5. Remove the valve cap from the valve cap stem. Activate the TPMS 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, turn the ignition switch to LOCK and start over beginning with Step 2.
   
   
6. Proceed to the passenger side front tire, and repeat the procedure in Step 5.
   
   
7. Proceed to the passenger side rear tire, and repeat the procedure in Step 5.
   
   
8. Proceed to the driver side rear tire, and repeat the procedure in Step 5.
   
   
9. After hearing the confirming horn chirp for the driver side rear tire, check to see if the TPMS low tire warning light and the DIC LOW TIRE messages have turned off. If yes, the TPMS sensors have been relearned. Turn the ignition switch to LOCK/OFF.
   
   If the low tire warning light and the SERV TPM message on the DIC are on after completing Step 5 for the driver side rear tire, the sensor relearn process has not been successful. Turn the ignition switch to LOCK/OFF and repeat the matching process beginning with Step 2.
   
   
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.

As an alternative, others have successfully used the following method which is easiler and seems to work equally as well:

1. 
   
   Start with the first part of the procedure:
   
   The TPMS sensor matching procedure is outlined below:
   
2. Set the parking brake.
   
   
3. Turn the ignition switch to ON/RUN with the engine off.
   
   
4. Turn the exterior lamp switch from AUTO to OFF four times within three seconds. A double horn chirp will sound and the TPMS low tire warning light starts flashing. The double horn chirp and flashing TPMS warning light indicates the TPMS matching process has started. The TPMS warning light should continue flashing throughout the matching procedure. The LOW TIRE message displays on the Driver Information Center (DIC).
   
   Then just start the truck, release the parking break and drive it for about 5 minutes. The truck will automatically learn the TPMS and the light/display will go out.

Nicely done Dave. Thank you for contributing to the how-to section.

Any idea why my light won't turn off? I did the alternative method and it still says to service the tpm. These tpm's were replaced about a month ago and I took it to a tire shop originally when I couldn't get it to reset and I was told sometimes it just needs to be driven a little then it will go out. But it's been a month and no dice.

Maybe I should try the full reset method with each individual tire??

Have the Sensors been "reset with a tool? New TPMS Sensors are shipped in "sleep" mode to preserve the battery life and the system needs to be reset initially with a TPMS tool to activate them.

I just replaced one of my sensors using one from orange, and i bought the kent-moore tpms rest tool for around 70 bucks and it works great, noticed that after the sensor was replaced and i did the reset with the tool it still wouldnt turn the light off, so i disconnected the battery for about an hour, did the reset again and no trouble since, also had trouble with my headunit and the battery disconnect for around an hour sorted that out, somtimes i wander if i bought a truck or a super fucking expensive computer or smart fone that you have to do a battery pull to reset everything.:true:

Updated to Add AC Delco Sensor Part Numbers and Torque Information.

Would this work on the 2nd. Gen trucks ???

I've successfully re-set my TPMS via the 'at each wheel' method, but when I tried to do it today, it didn't work. I was careful to follow procedure, but the DIC message would never extinguish 'low tire-check TPMS.'

So, I tried the 'set pkg brake, 4 times to off position light switch, hear the double horn' and then 'drive it for a few minutes' method, and about one mile, the 'check TPMS' message vanished. Subsequent re-starts have shown the message to be gone. If you have an issue doing it by the manual, you might try the 'quickie method,' it worked for me. Thanks. I had recently replaced my tires, and they replaced one TPMS sensor they said was bad, but they weren't able to re-set it either 'by the manual,' after trying several times.

Funny TPMS story. Purchase a set of Michelins, for my truck, in June, at the local BJs. Last week I ran over something on the freeway that sliced open the sidewall on the left rear. Went to BJs for Road Hazard Warranty replacemnt tire. When the tech finished and handed me the keys he told me the TPMS sensors checked good but I would have to stow the spare under the bed before the TPMS light would go out. I was so surprised that I couldn't think of anything to say. Just shook my head and went home and did a relearn and the light went out.
