Tire Presure Light!
 

How do you re-set the tire presure light on my 05 3.0

its in the iwners manual. turn key to first position. hold button near shifter till blinks or stays on then start truck and drive away it will set itself. but make sure your tire pressure is correct. if u changed rims and the sensors are not in the tires it will not shut off.

Almost right. Owners manual tells you how to set it, if you change rims and press the button it will simply turn the system off. I did this routinely on my X.

I read the section in the owners manual on tire pressure monitoring and I was under the impression there weren't any sensors inside the tires? I thought the manual said the computer uses the ABS sensors to detect if one or more tires has a different rolling diameter. Is this the case or are there sensors in the tires?
