Tire Sensor Bad / Missing

2004 Liberty Limited

The overhead display is showing "Tire Sensor Bad / Missing" when you start the Jeep. I know there all there, so how can I tell which one of the 5 are bad? Is there a way to test them? I saw something about training the sensors when cycling though the menu, but I have no idea how to use that feature (owners manual is MIA). Can anyone give me an idea on this? I'm new to the world of Liberty.

Also, where can I get a replacement sensor? The dealership quoted me close to $250 for all of them and said they all have to be replaced.

the batteries are sealed in the sensors. I am sure you can get them from Rock Auto and get them installed at a tire shop or independent shop cheaper than a dealer.

My friends 2004 Grand Cheroke has a bad sensor and it says with on is bad. I am not sure what my liberty does. I have only had the tires aired down to off road, all 4 at once and all it told me was "low tire pressure"

The batteries only last about 5-7 years in the TPMS sensors,so most likely a dead battery or 2 and is best to replace all of them due to age,and no you can not just change the battery.

Since you have a 2004, have you tried to retrain them? Air them up to 35 psi, retrain them and see what happens.

Last time after I aired down for off road and then reinflated I had the same display warning. I retrained them and it solved the problem.

You will need a training magnet (should be in the Jeep somewhere) and you can get the procedure on line. It is very easy. If you don't have a magnet you can get it from justforjeeps.com for about 25 bucks.

I'm thinking it might be the spare sensor since the overhead display is still reporting the pressure of the other four.

Realize this may be a silly question, have you checked the tire pressure in your spare?
