OK, here is the story. Over a year ago I got new tires and wheels, I had the dealer flash/change the TPMS to work at 28 psi as I was running at 31 and hated the damn light always on. All has worked great since......until yesterday. I get up to go to work, hop in start it up and now the ding and the damn light comes on. I check my pressure in everything including the spare and they are at 30. So I add a little air up to 31, drive all morning and the light is still on. So I add a little more air up to 33 and the light goes off. I drive till I get home then drop the pressure back to 31 and the damn light comes back on....

So my question, does the computor revert back to it original settings? What else could be causing this?

 

have you had to disconnet your batter for any reason recently? if so, yeah, your computer most likely reset itself.

 

Yep.....I was working on my wiring 2 nights ago......Damn....Thanks
