One TPMS Sensor Malfunction Jeep (toad)

I have a TPMS sensor in 1 tire that went out, but I figured I'd wait until I replace the tires to think about getting it fixed. I found out which one it was by using a procedure to "rediscover" the sensors. I searched online and found the magic codes, and I'm sure it is different for every vehicle so try to find it for yours. Mine went something like turning the key on (not starting the vehicle) and off 5 times, pressing the gas pedal on the last time, and the horn would magically sound. The display would tell you which tire to go to, and you'd have to place a strong magnet around that valve stem until the horn sounded again. If eventually sent me to the sensor that wasn't working, and it couldn't find it, so I now know which one is the problem.

See if you can find some magic codes to help you "rediscover" the sensors, as that may be all the problem is.

Thanks for the replies. I have since learned that these TPMS systems can be a big PITA.
But I did forget about checking the tire pressure on the spare. If that don't fix it, maybe....most likely it won't get fixed.

If the pressure sensor is bad, make sure the replacement can be read by the Jeep. I have a 2004 Liberty and couldn't get the Jeep to recognize the aftermarket sensor. At least on my model, only the OEM sensors work. The dealer has to manually enter the serial number of the sensor into a programmer, then download the info into the Jeep. On the bright side, the sensor cost was the same at the dealer as it was at the independent tire store. Too bad I already paid for the one the Jeep won't recognize. Not sure if all vehicles are this picky, but you may want to check before buying a replacement .

My car after rotating tires will tell me there is a tire problem. The reason is that one tire was replaced under warranty and it is just slightly larger in diameter. Every time I rotate the tires I need to reset the TPMS. I don't know if that is your problem or not, but is something to think about.

TPMS have been required in all vehicles since 2007. Most systems don't have individual displays, only an idiot light. Only a scan tool for TPMS can tell you which one.

I assume your Jeep has a overhead display that shows the individual tires

My 2002 CG Overland has the display that shows each tire including the spare. Even better the original TPMS batteries inside the tire are all still doing great

Probably have to take it to a shop that has the TMPS tool that can read the individual sensors. I had a sensor go bad and it cost about $40 on Amazon then another $20 to replace it.
