.... aNyOnE know the ins-and-outs of this? ... my tire pressure is good ... but the OH console says they need attention. Faulty sensors ? ... best just to broom-it-all away ?

First what kind of car is it ?
Second have it scanned to see if it has any codes in it. Ron

if the pressure is good then its a bad sensor..did you do any tire work lately?..adjust the air pressure?..if you adjusted the air the car needs to be driven awhile to clear it..

did you check all FIVE tires? or just the 4 easy ones?

Yes what kind of car would help. You may be able to "learn the sensors" with your OC If it's a option you'll need a good magnet to do it.

if your pressure is too high it will turn the light on too.. I had a 2011 ram 2500 that I pulled my gooseneck with.. the first time i hooked it up I added pressure to the tires due to the increased weight and truck went to heavy load mode.. a couple days after I unhooked the trailer the tire pressure light came on checked all the pressures were above the minimum sensor pressure and below the maximum tire pressure on the side wall but they were above the maximum that was programmed in the computer for an unloaded truck,, found that out after i took it to the dealer for the light..
