OK ! can anyone tell me HOW the the tire inflation info, system works and what off of mine works fine when i get a low tire any of the 4 ? the goofy thing says low tire inflation i check tires fill em up reset it and i'm fine but how's it work and off of what ?

 

sounds like you either dont have a tpms sensor in one of the tires or one tpms sensor is bad. the tpsms sensors send wireless signals after they read the psi in the tire, if its lot the error goes off. this is an option that is used on many newer vehicles. I would, if i were you, get the sensors checked.

 

2000 montes dont have a tpms sensor , they use wheel speed .

 

The system warns you when one tire is 5PSI lower than the others
