I have a 2017 Camaro SS 1LE, same generation and system the C7 uses, you still have to use the TPMS relearn process if you want they cars TPMS system to know what wheel position the TPMS sensor is located in. That part of the process has not changed at all no matter what generation GM vehicle you have.

If you want the vehicle to know which wheel position it is located in you most certainly have to use the TPMS reset tool to relearn the wheels positions.

I have switched wheels several times and it knows what wheel is where because if I add air it changes that tire in that position. The snow tires on now are directional so they are in same position. Maybe further investigation is warranted.

same here and we’ve done this at least a dozen times. On our 2009 cobalt SS we did have to use the older process

THERE IS NO NEED TO PAIR TPMS ANYMORE. JUST INSTALL WHEELS AND DRIVE. THEY SELF-PAIR. YES, THERE IS A MANUAL METHOD IF THE SELF-PAIR FAILS, BUT IN MY 3 YEARS OF OWNING AND TRACKING MY C7 MINE NEVER FAILED TO WORK.

Yes the system knows the sensors have been paired to it, you still have to go to the TPMS screen on the DIC and put it into pairing mode and then use the TPMS tool to program where each wheel is located at on the vehicle. With a staggered fitment there is a 50/50 chance on each end of the car you could get the wheel back in the same position as last time, not always the case on a square fitment.
I have a 2nd set of wheels and then I also have 2 rear drag radials. While the car knows when they are on it because the sensors once they are activated register, I still have to tell the ECM where they are located at on the vehicle.
There is no way for the car to know where each wheel is located without using the TPMS tool to tell it that info. Sorry, but that is how it works yes even on the C7 and C8.

I have 433mhz sensors as well, my car is a 17 Camaro SS with the 1LE track package. So I have the E-Diff and the PTM modes and the dual mode TPMS sensors that provide air pressure and air temperature inside of the wheel, just like the C7 uses.

You got it wrong on the C7. It is an automatic process and we don't have to do squat to get the TPMS to figure out what wheel they're on and to transmit the pressure reading.

Again, this does not re-learn or pair the TPMS sensors with each wheel position. All this does is puts the vehicle in TPMS re-learn mode. At that point you have to use a TPMS reset tool and go to each wheel position starting with the drivers side front wheel and excite the TPMS sensor using the reset tool. Then follow the side marker lights to the next wheel position until you are done.

Your Camaro experience is irrelevant for the C7 (and probably the C8). The C7 automatically relearns.
This is from the Owners Manual:
TPMS Sensor Matching
Process — Auto Learn
Function
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
tires or replacing one or more of the
TPMS sensors. When a tire is
installed, the vehicle must be
stationary for about 20 minutes
before the system recalculates. The
following relearn process takes up
to 10 minutes, driving at a minimum
speed of 19 km/h (12 mph).
A dash (-) or pressure value will
display in the DIC. See Driver
Information Center (DIC) 0 114 and
Tire Messages 0 129. A warning
message displays in the DIC if a
problem occurs during the relearn
process.

I swap wheels all the time. I’ve done it at the track with back to back wheel swaps. Stock sized to 18’s with slicks. Took my car about 2 min of driving at 5 mph in the pits and my car always picks up the new sensors. No action needed other than swapping wheels with Oem Senors and driving.

Sorry to hijack this but the comment that the TPMS sensors input into the eDiff operation surprised me.
I have a 2016 Z51 and use MPSC2 on separate wheels for track. I did not get TPMS, as I always check my pressures after every session, and did not want to deal with them malfunctioning under extreme use...(e.g. bashing curbs).
Certainly I don;t want to compromise the performance of the eDiff... so question for you tech gurus...
How does the eDiff function without signal from the TPMS.??
My assumption is that the eDiff assumes the tires are at operational pressure, and only reacts if it detects an "out or range" condition 9either too low or too high)....so if the TMPS signal is missing, it just operates normally...
Is that correct, or does the absence of TPMS signal adversely impact operation?
Thanks

I could never get a 100% definitive answer of what the eDiff does with no TPMS. Even Jim Mero told me on FB messenger that he couldn't recall. Thus, I went ahead and put TPMS in my track wheels. Never had an issue with them and I eat all the curbs at VIR.
We know the eDiff is less aggressive when TPMS tells the car the tires are cold... it's the temp data, not the pressure data, that matters.

Thanks, I didn't notice any weird behavior.... assuming it will work OK.

Perhaps not the best place to ask, but does anyone know if there's a way to purchase a set of TPMS sensors now? Preferably online? Have an aftermarket set of wheels and tires, would like to get the tires mounted, but need the sensors first.
