It was realllllly cold this morning and my tpms alert came on. My tires are all showing 34 psi now, but the system is still showing the alert. How do you reset it?
My TPMS got 'stuck' when I changed t using my Procal. In order to get it to reset, I had to disconnect the battery terminals for a few minutes then reconnect. That did the trick.
Once the tire pressure drops below a certain threshold and trips the warning, you have to fill each of the tires above 35 psi to reset it...that is assuming you did not alter the TPMS settings with a procal.
Mine is doing the same thing. Also after I rotated the tires it has not learned the new location yet. Its been two months. The dealer says I need to pay $30 to fix it. Crap!
My 15 kept throwing the TPMS even after my flashcal offroad flash. Had to pull the neg and turned on the headlights for 30 seconds and reconnected. It "resets" the cluster, no more tpms issue here.
I will give that a try right now. Thanks for the help! This is the 5th time since November that TPMS has come on. Stays on for a few days or a week then goes off.
What pressure are you running? If it's not the pressure listed on the door jamb the TPMS is going to go off, then it could take awhile to re-set. If the door jamb is 35 that's what the TPMS threshold is. You can use a Procal to adjust it if you want to run a lower pressure. If your TPMS isn't learning where the tires are there could be another issue and you'll have to take it in.
The weird thing is the TPMS seems to work just fine. Pressure read correctly and change as the tire warms up, just throws the check TPMS warning and does not relearn after rotate.
There are 3 sensors that pick up where the tires are with connectivity. One or more of them could be bad. 4 sensors aren't used because the 4th tire is picked up by the system due to the process of elimination by the computer. I'm not making it up. That's the way it works.
