Tire valve (possibly tpms-related) for 2014 Buick Enclave

Our 2014 Enclave had a slow leak for a while, dropping a psi or so each day. We kept filling it up every few days until we had a chance to take it in.

Independent mechanic (not Buick) said it was the tire valve and they wanted to order an oem part. The part took several days but they finally got it and installed it.

When we picked up the car they said it would take a day or two for the car to 'register' the new valve (again, tpms-related, I believe), as the car was currently saying 0 psi at that tire.

It's now been 1 day with no update.

Does any of this sound legit, in that the car wouldn't immediately (or within minutes of driving) register the tire pressure?

Is it really possible that it could take a couple of days? I would think that the valve would immediately register the psi upon being installed, as the tire pressure immediately hits the valve (it doesn't 'build up' over a couple of days).

Thanks for any comments/suggestions.

 

might try the relearn procedure check your owners manual for how to get it into relearn mode you do not need any special tools as you can do it by letting air out of each tire until the horn honks but the cheap tool allows you to do it without letting air out. video below.
Tire Pressure Sensor Relearn / Reset / Recalibration!!! - YouTube
if that does not work it likely needs the sensor programmed as many do not come programmed ,may need to find another tire shop or see the dealer the tool they use is fairly expensive so many small independent shops may not offer this you can also purchase 4 pre programmed sensors and just have any tire shop install them and do the relearn procedure 8 year old car likely going to start having issues with them as the batteries start to fail they do not cost that much on amazon.

 

Actually they are pretty cheap, this is the one I picked up on sale a few years ago for $10.

that just does the vehicle relearn procedure it does not program the sensors, much easier and quicker to use that than letting air out of the tire.

 

Not sure what your referring to by reprograming, every one that I have replaced just had to be relearned by the car to it's position. The TPS just broadcasts a very short distance signal to the the BCM when the pressure is low.

If the car is not reading the signal then typ it means the TPS is bad or the battery is dead.

 

No. TPMS has to be mated with computer with handy dandy tool. BCM does not "just reset" pressure. data. It needs to recognize the sensor. Hence the mating process.

 

Thanks for the responses so far. I checked our invoice and here's the exact part (in case it helps determine what I need to do next):

They also commented on this invoice that:

 

Just bumping this to see if, based on the part # that was replaced, anyone can confirm exactly what needs to be done in order for the car to 'link' with the new sensor. We went back to local shop and they still had no luck. I hate to go to actual Buick as I'm sure it'll be $$$ to fix...

Thanks again!

 

Really your options are likely only a few see the dealer where they may be able to program the new sensor or replace it if its defective but most likely they can at least most likely get it repaired for you.
Call around other tire shops see if they have the tool to program tpms sensors and if they are willing to look at it if there is something wrong and they can't program it they may suggest replacing it also or seeing the dealer.
Last option would be to buy a set of preprogrammed sensors for your car have a tire shop install them and rebalance all the tires, do the relearn procedure yourself this often works for gm vehicles but if there is something else wrong then it's still not going to work and you're still looking at going to the dealer.
