TPMS - says the tires low, but its not

[ride4lamar]

I have seen many TPMS posts but didn't see one that answered this...

- First issue is that the TPMS is telling me the left front tire is in the low 20's. Its been saying this for about a week and a half yet i keep checking it and its in the 30's like all the other tires.

- Also it tends to have the tires mixed up, it detects a spare swap, but sometimes the drivers side and passengers side are switched on the monitor itself.

What year is the Jeep?

Are you checking all 5 tires?

Check to make sure when tires are cold, that they are all at the same pressure and see if it still shows one low.

ive checked all five - even brought it to the tire place that put the new ones on two and half months ago. Pressure was fine. Its been showing low (about 12 pounds lower than it is) for about two weeks now

Its a 2004. Just shy of 70K on it.

If its an 04 retrain the tire sensors and see if that fixes it. Procedure for doing so is in the owners manual.
