Subject: Rubber Valve Stem Pressure Release Learn Method - keywords check chirp horn low monitor program relearn tire tpm #PIT4220 - (12/28/2006)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

 

Condition/Concern:

Some customers may comment that they are unable to get the TPM system to learn the new style rubber valve stems using the pressure release method. This may be inconsistent from one tire sensor to the next and one vehicle to the next. If the J-46079 tool is used the learn procedure can be done.

 

The release of air through the valve stem sets up a resonant vibration frequency that can trick the TPM Sensor into thinking it is in motion. This causes the sensor to transmit multiple pressure update messages, not Sensor ID learn messages. The Remote Control Door Lock Receiver (RCDLR) does not recognize the pressure update messages when it is in a Learn Mode. This will not allow the vehicle to acknowledge the sensor with a horn chirp, and the learn procedure cannot be completed.

 

Recommendation/Instructions:

For rubber valve stem sensors only, if you have any problems performing a learn procedure using the pressure release method, use the J-46079 tool to perform TPM Learn procedures.

 

For customers who are unable to perform the learn procedure at home, perform the learn procedure using the J-46079 tool and advise that engineering is working on a fix and parts to correct this condition will be available in the future.

 

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

 

 

 

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

I was asking questions over at BITOG, about the problems with the relearn procedure and the TPMS and a GM tech posted this TSB. I hope they find the fix before my next tire rotation. Oops, title should be TPMS TSB

That TSB is almost a year old,I'm pretty sure they got it solved by now,I know the tire pressure sensors have a different part number than they did earlier this year.

I just took my truck in last week. No matter what I did I could not go through the relearn procedure. They had to hook it up to their computer and use the wand to relearn the tire positions. I asked if there was a fix so I would not have to return every time I rotated tires and they told me there was not.

I cannot make mine relearn either....kinda sucks a $30K truck and it has a service light all the time.... :rollin:

Me Too? I put air in mine last night and the DIC told me I had a tire pressure monitor error. All the tires pressures went blank. Tryed the recalibrate (what a pain in my a@@). Didnt work. :D

      Notes 7/18/2026   3,400 miles on this batch of Mobil 1 Euro 5W40 since the GDI pump replacement. Alcohol runs very clean when ring seal is tight and the sump isn't getting hosed with fuel. Checked oil level at fill up today as is my practice and grabbed a white Kleenex to look at the color. What color?  I was going to change it but.....

      Gas Prices

      Interesting, I suspect I would have fueled up in Lee Vining as the day prior I would have filled up either in Laughlin or near there and maybe again before I entered Death Valley and once out the other side late that evening as I kept on driving into the night up near Lee Vining. Next morning I most likely fueled up in LV before heading over Tioga Pass into ( as I refer to it as "Yose .... Mite" 😁 ). And again that was 19 years ago but the price then must not have jumped out at me like the 5 bill a gallon theme of nutty cult hippy country Big Sir or head so far up their rear Aspen. I'd be curious to know where the highest prices are in the lower 48, I probably would not be far off to guess somewhere in Cali forn ie. Coldfoot and Prudhoe bay may have those prices beat but that is a whole other world up there and when prices are more normal elsewhere that is about what they can be up there I believe in no mans land. Anyway interesting that the 395 corridor is hosing people and the thing is, its tourist season and its not like there are a lot of competition options when driving up that highway from what I could see. Yup, big ole Boaterhomes and various other RV's ahead and behind me at the Yosemite entrance gate and they have to get their fuel somewhere.

      Those can be high, as well as the big California cities. The ones that will pop your eyes out are the 395 corridor on the Eastern side of the Sierra Nevadas. Lee Vining, $7.19 for regular and $8.89 for diesel is what the Google said right now.

      Correct.  2019-2021 model years are serviced by a different p/n.  19420611.  Recall 2021s use 19420611.   The recall engines 2022-2024 model years are serviced with 12740076.     The difference between 19420611 and 12740076 is GM changed injector size for 2022.  The injectors are smaller on 12740076 with smaller injector bores in the cylinder heads to match the smaller injectors.  So you can't install a 19420611 in a 2022-2024, and you can't install a 12740076 in a 2019-2021.     Both engines are the replacement engine p/ns that are in the L87 recall.  So both of these are the updated engines.     Here's a version of the L87 recall with the p/ns for all the parts needed.    RCRIT-25V274-7075.pdf   Note it shows 19420611 and 12740076 with an asterisk to a footnote "Use the VIN and the GM Electronic Parts Catalog (EPC) to determine which part to order if two or more part numbers are listed for the same part, as it may vary by vehicle options."
