overinflate to maybe 40 and drive a while, then let it back out to 37

Did you check the pressure in the spare?
It will chime once for each sensor that is low, how many chimes are sounding at start-up?

Just go buy an AEV Procal Module and take care of the TPMS forever !!


Calibrate speedo/ adj auto tranny/ disable TPMS/ configure driving lights-etc !!

Jim, im only getting one chime..so maybe i will check the spare but that just seems crazy since the spare is hooked to the back door. Thanks for the advice and i will try these helpful tips.

It may be on the tailgate, but it still has an active sensor on it. Why wouldn't it?

same problem the tires are all at 34 lbs and the sensor light wont go off, i even disconnected the battery.

any ideas?

bad sensor? will a bad sensor make the light saty on forever or do they normally go bad and then stop sending signal so they dont cause the light to trigger?

This has been posted before from the manual.

A tire pressure monitoring sensor is located in the spare
wheel if the vehicle is equipped with a matching full size
spare wheel and tire assembly. The matching full size
spare tire can be used in place of any of the four road
tires. A low spare tire will not cause the “Tire Pressure
Monitoring Telltale Light” to illuminate or the chime to
sound.
The “Tire Pressure Monitoring Telltale Light” will
illuminate in the instrument cluster, and an audible
chime will be activated when one or more of
the four active road tire pressures are low.

Again...It's in the manual.
Reason? The centrigal force is what activates the sensor through inertial movement caused by the rolling of the wheel. The spare doesn't roll.

Yeah, crank 'em to 38+. As has been said before, TPMS won't reset until the pressure is quite high.

What tire pressure is on the tab on your door frame? I know for Rubicon's they think 37lbs is optimal. The sensor is supposed to turn on the light at 30lbs and turn off at 34. A lot of times it will take 35 or more to get mine off. btw it is adjustable by the dealership. I lowered my target to 30lbs so that when airing up after wheeling I didn't have to hit 35 all the way around to get the light off. The light is not that big of a deal, but unfortunately when it is on my odo will not dim with the dash lights, so it stays on full bright. that annoys me.

Yeah, well it's crazy because this Spring, when I rotated(tires are aired down for the winter) I aired up all the tires on the ground, kinda forgot the spare, alarm stayed on, aired up the spare, alarm went off...why?
