TPMS on my 2004

[JasonF]

Supposedly my 2004 Explorer has the TPMS system. I was checking my tires the other day and noticed that my right front was down to about 22 psi while the others were all at 32. Why didn't the TPMS light come on on my dash? Does anyone know how low the tires have to be to set it off? Seems like 22 psi is more than low enough.

It's a very low percentage is when the TPMS light will illuminate. I can't find the exact number, but its pretty low.

Found it: 25% -- so at about 20psi your information center/light should of come on: read more

Ok I screwed up. I looked at my owners manual tonight and realized that not all 2004's have this feature. I thought it was standard on the newer ones; guess not.

nope, but in 2007 it should be on all newer vehicles produced in the U.S.:
