i had the low tire pressure message and light come on back when i was visiting california, about 3 weeks ago..i checked the tire pressure, and a couple tires were maybe 5 psi low at the most.. i aired them back up to the right pressure (as stated on the door pillar sticker) and the damned light/message is still coming on.. how do I reset the TPMS? it says in the manual to just drive the truck 20mph+ for about 2 mins after getting the tire pressure correct, and the light/message should turn off. i have done that...
