Tire Pressure System Reading Low

The other day my dash alerted me that I had low pressure in my tires. I manually checked all tires, and they're all where they need to be.

Any reason why the system may be going off? Does it have anything to do with the weather getting cold?

What year JK do you have?
Does the TPMS display give an actual pressure reading and tire location?
If the tire pressure is where it needs to be, as it says on the tire pressure placard on the door post, then it has nothing to do with it being cold. The cold will cause the pressure to drop and you would see that on your tire pressure gauge. How did your reading compare with what's on the placard?

I have had mine throw an alert for no apparent reason several times over the years. It's still a mystery to me why it does that.

I had that problem on my ’08 a couple of times. Pressure was fine but I added more just to see if the light would go out and it did. Later I would adjust the pressure back to where it was and problem was gone. I don’t know why it did that and never gave it much thought either; to many other things going on in my life to worry about it.

or did you get a JK but not change profile? If so what year, etc.

I haven't had any problems with my TPMS system in over 5 years-

I disabled it with the AEVPM-

If I am not mistaken the TMPS sensors are rated for around 7 years battery life. They normally are on a band around the rim and some are on the valve stem. With that said if you checked all the tires and they where correctly inflated, then you may have a sensor starting to go bad.

Here is some pretty good information on them.

WJ or JK they work the same. Only difference is you can't disable TPMS on a WJ without replacing the entire EVIC with a non TPMS model

You still have concerns about battery life, and you should remember to check your spare. Though in a WJ you would KNOW which tire is low, their TPMS is way fancier than the JK dummy system.

I recently had the same problem in my brand new 2014 with after market tires and rims. I just plunged in my AEV procal and shut the tire monitor off.
