TPMS not reading correctly 2017 equinox

I just filled my tires on my equinox to 34 psi each. Checked the pressure at each stem with a manual and digital gauge.
Went in the car and the tpms reads 40 psi for each tire. Reset the tpms and still 40 psi.
What do you trust? The pressure at the stem or the tpms?
I had this same thing happen in a 2016 chevy cruze.

I started the vehicle but didn't drive it. I will give that a try right now. Just seems strange that 2 gauges read 34 psi, but the tpms shows 40.
I will update if driving fixes it.
Thanks for the reply.

No dice.
I reset the tpms in park with the car on. Let it learn, then drove. The pressure on 2 tires dropped to 39 psi, but went back up to 40. I think I'm going to have to get one of those auto fillers for the compressor. I just don't know how 2 gauges could be wrong?

TPMS is not precise like a tire gauge. It's there to warn you of a impending flat tire so you can address it before tire failure and loss of vehicle control. Most trigger a warning at 26 psi. . All the TPMS in my fleet are always off a few pounds on my fleet.

Additionally, you have to follow this sequence to activate each sensor and complete a re-learn:
Driver front
Passenger front
Passenger rear
Driver rear
You will know when each sensor has been learned correctly because the horn will beep when it’s done, then you move on to the next. The re-learn is complete when the horn beeps twice.
There is also a time limit. Once learn more is enabled, you have 2 minutes to complete it. After that, it times out and you have to start over again from the driver front tire. It’s best to make sure the sensors are “awake” before attempting a re-learn by driving above 25 MPH for 2-3 minutes.
If the readings on your info center differ more than 4 PSI (above or below) from your gauge, there is an issue with the sensors or with the module. If it is the sensors, sometimes a successful re-learn will correct the issue but there’s no guarantees.
As for when the sensors trigger a warning, it depends on the manufacturer’s chosen calibration (programmed into the module). I’ve seen some that go off with as little as 2 PSI difference. Dodge/Chrysler sensors (on their vans at least) are calibrated for 36-40 PSI - if the pressure is outside this range (could be one tire or all of them), the warning light comes on. GM’s service manual states a difference of 1.2 PSI will trigger a warning light.

The method I used was to start the car, reset the tpms in park, (it honked twice) let it finish relearning, then drive.
If I put the car in drive after resetting the tpms it turned off the learning notification.
Not sure what to do. I bought an auto fill gauge for my compressor. I set it to 34psi and filled the tires. 2 gauges show 34psi. The tpms reads 41psi. I am trusting the gauges till I can figure out the correct procedure. It shouldn't be this difficult, oh well.

The sensors have to be individually activated so the car knows which sensor is in which position. If you’re having difficulty figuring it out, go to a shop.

You need to check out the total pressure control of the car which will help to run the vehicle in a good way. There is written information is available for many people who want to get the edubirdie option for the writing content which is available on the edubirdie review option for helping out the students in good way.
