My TPMS light came on....

....yesterday morning. I guess the screen layout is like looking down from the top of the Jeep, so the driver's left was flashing 33. The driver's right was on 34, passenger left 34, and the passenger right on 33. Only the driver's left was flashing 33 and said to check the TPMS, inflate to 37.

I got home that evening and aired all 5 tires to 35psi. I know the spare is not displayed, but checked and aired it up anyways. I didn't drive it any the rest of the evening, but nothing changed on the display on the way to work this morning.

This afternoon when I got home, I swapped the spare out for the driver's left. I made sure all tires were aired up to 35psi, then drove around the neighborhood. The light went off and all four tires show 35 on the display.

So, that being said. Should I swap the wheels back and drive around, or do I have a bad sensor? I didn't have any issues with this last fall when it started getting cooler. Do you have to drive around to reset the system?

Thanks everyone.

Maybe tops the now spare on a different wheel location and see if it goes on again? I would think that would indicate a bad sensor.

Yes you have to drive so many miles down the road for them to reset/reread the values. Sorry I donít know what that is

Research indicates that it requires 10 minutes at >15mph to retrain the TPMS for the tires. Since your light is out, I think you will be fine.

You didn’t solve the problem, you just moved it to the spare where it is off the radar. In order for the TPMS to stop complaining about a certain tire, that tire has to be detected at 37 psi or more, as your display states. So you should have aired the offending tire up to 37 or more, wait for it to sensed, and then you can air it back down.
The low-end trigger is typically 33 so probably your other tire at 33 was about to trigger as well.
