Medical Definition of adhesive. 1: an adhesive substance; especially : a substance (as glue, starch, paste, or mucilage) that bonds two materials together by adhering to the surface of each.
The sensors physically measure the tire pressure in each tire and report it to the vehicle's instrument cluster or a corresponding monitor. Some units also measure and alert temperatures of the tire as well. These systems can identify under-inflation in any combination, be it one tire or all, simultaneously.
Re: how do tire pressure sensors work? Yea the TPS are in the valve stem and use RF to transmit data. I think its if a tire is 5 psi or more out of spec then it gives the error but I may wrong, it could be more or less. They could have damaged the sensor when the tire was replaced. __________________. .:PDXGRAFIX:.
