did all that the only option i got left was from iqforyou ima go to a mech to put 35 psi front and 33 psi back, but to answer your question i hold the pressure button down while on "on" for over 2 minutes, all i got is a solid tpms pressure color
I don't know... I think I put 45 psi in mine because it was just under the max and I didn't want to get my rims dented in case I hit a pothole. I also don't run the TPS on my new rims and I just ignore the light.
When it is set at what ever pressure you want to run. You should be able to hold down the button. And then that will be the set pressure.
You might have one damaged and that is why it isn't working. Have somebody hook up a scanner and see if any codes for the TPMS sensors are stored.
