The places equipped with a 'gauge' on the air hose, usually are so broken they are inaccurate (a safe and prudent standard when dealing with any tires in general). Anyone who has read many of my 'TPMS' replies know I am a 'tire gauge only' owner/operator with all my vehicles. I am so glad the XF isn't incorporated into the 'MIL', and is easily bypassed from lighting up on the dash. This helps in case I move to a state that does have vehicle inspections. Owners who have vehicles that incorporate the TPMS into the MIL are screwed (no I have no idea which vehicles use the MIL for it's TPMS). It is extremely hard to fathom how much they (owners) would have to spend to have those systems maintained.....

I just turned off my TPMS light and now use a much better aftermarket TPMS that has very accurate sensors mounted on the valve stems as a cap replacement. The head unit is small and solar powered, shows not only the current pressure in each tire, but the temps as well. You can also set alarm/warning for both pressures and temps to whatever level you want.
The whole kit cost $50 and took 3 minutes to install and gives so much better information than the factory TPMS.
