I got a question about the Tire monitor system. So my 2012 just shows the flat tire symbol when the tire is low. I know some vehicles can show the pressure of each tire. So are all the TPMS sensors the same and it is dependent on the cars ability to show actual pressure or are the sensors for the ones that show each tire reading different. I ask because I want a system that says each tire and upon researching have seen ones that you screw something onto the plug part in order to show levels. So I was thinking if the sensors are all the same there must be something out there that will read the pressure. And I would be willing to buy that display if available. Any ideas?
