[QUOTE="wheelman55, post: 1394087, member: 19793"] I had one sensor go bad on my 2018 Raptor. The dealer replaced it under warranty. This TPMS would intermittently read nothing though. Try doing a few things. [LIST] [*]Check the actual air pressure with a pressure gauge on all tires. Compare what the gauge reads to the values on the dash. Choose one. [*]Air the tire down on the misbehaving corner, say to 28. Drive around for a few miles. See what the display says. 28 psi should give you the orange color with a dashed line instead of a psi value. [*]Air the tire back up to what you want the pressure to be. I recommend 34 psi for the rear tires. See what the display says now. [*]While you are at it...air the front tires up 4 psi above the rear tires. I like cold psi of 38 front/34 rear for highway. Just keep that 4 psi delta front to rear. If you are airing up the tires when they are warm, bump the psi up 2 psi to 40 front/36 rear. [/LIST] Let us know how this works. Best. [/QUOTE]
