There is always the possibility of getting a bad sensor. I had a bum new one when I swapped wheels.

 

 

 

I have always had to drive about 10 miles before our rigs turn the TPM light off.

 

As an update, my TPM problem has not changed. For 4 years now the "Check TPM" has come on intermittently. Goes away intermittently. Works for days without showing up. In those 4 years I've changed battery, all tire sensors, reprogrammed the sensors and converted from the I5 engine to 6.2 LS3. Nothing has changed the status. It still behaves exactly as it did 4 years ago. Also I've yet to have found any source that explains exactly HOW this system works (where is the antenna, where is the control module, what is the flow of logic from the tires to the BCM). I'm beginning to think that no one understands this system except for GM.

 

Mine is fine except during cold weather. When it drops below 30 degrees, I just plan on the TPMS going intermittent. And know it will return to normal once the weather warms back up.

 

This is/was my first winter with my 2006 H3. I have also noticed little glitches when the temps get really low. As of late my "serv TPM" message has been on and then yesterday the actual "low tire" message and light came on. My LF ABS sensor has been setting off the ABS and Stability messages; this also did not start until the first real blast of arctic weather with below zero temps hit here a month or so ago. Maybe not related but the Vent Valve Solenoid has the engine light on as well. It started with the "fuel cap" warning and a p-code that signified a small evap leak. That mysteriously went away then the engine light came on and has stayed on with the Vent Valve Solenoid code.

 

I'm in the same boat as you, since I bought this vehicle in 2015 it's been the thorn in my side. I get so frustrated dealing with the GM dealer about it too. My warning light will NOT start flashing when entering the TPMS "learn mode", it just stays on steady. The manual says it is suppose to start flashing and "remain flashing" throughout the learning phase. But, since I put in aftermarket sensors back in 2015 when I put on new tires, the dealer keeps wanting my to buy $400 worth of new factory sensors, before they proceed. What does functioning, or non-functioning, or non-existent sensors have to do with the fact that the light on the DIC will not flash when in the learn mode? I guess the dealer is located in the logic free zone.

I don't think GM knows how it works either.....how's that.

IT HAS TO START FLASHING TO BE ABLE TO LEARN THEM AT ALL. Why can't the GM dealer get past that part of this puzzle?

Everyone here has probably had to do this at some point, does everyone here see the light on the dash start to flash when doing the learn sequence? Please let me know what might be the problem. Thanks.

 

It is frustrating and I've come to the conclusion that we will never find out how this system works. After 5 or 6 years my "CHECK TPM" error has not changed in any way. It's still intermittent, it still has nothing to do with the TPS since they have been changed to brand new ones 2 years ago. Had the exact same behavior with the old sensors as the new ones. We don't even know the route of communication between the TPS and the TPM but it seems likely to be piggybacked on the security system. There's not even any information on WHERE the TPM is but it's likely to be nothing more than a subroutine running in the BCM... When I get the "CHECK TPM" message I just hit the button to clear the message and drive on...

 

I have reprogrammed mine once after fixing a flat tire, and the process went as it was supposed to.

As long as my tire pressure is set to exactly 38psi (all 4), my TPMS works, except when it's cold out. On cold mornings, I get the "Low Tire" message for about 10-15 miles of driving till the tires warm up.
