TPMS reading issue

Hey all,

Today I put Rubicon wheels and tires on my Jeep and I love the way it turned out. I also used the McGard wheels locks.

I have a TPMS in the jeep, after installing the wheels I get a warning message, the system isn't reading the sensors. What should I do?

I bought the wheels used, the guy said they have TPMS sensors in the wheels but there was no way for me to check myself.

Have you tried driving it around a bit? As I understand it, it takes time for a change in TPMS sensors to be picked up.

If, after half an hour if driving, they're still not being read, try unhooking the negative terminal from the battery for 5 minutes or so. That might shake things loose...

If you're not sure if the sensors are in the wheels, or if they're not registering after driving for 15-20 miles with one or two on/off cycles max., you can go to a tire shop where they can scan the sensors for battery life and frequency without breaking down the tires. If the sensors check out they can then plug a programmer into the OBD port and immediately synch. them. I wouldn't recommend disconnecting the battery for this type of issue.

I had to disconnect the battery for at least an hour to get the system error code to reset. Had to go to the dealer (or any tire shop like firestone, Goodyear) to get the computer to register the pressures but they could not get that idiot light to go out. The other day while trouble shooting I had the batts disconnected for an hour or so and error code reset. But keep in mind my dash was reading correct pressures before disconnecting.

I have driven over 25 miles today with 2-3 on off cycles. The light is still on the dash. Next weekend I think ill bring it to a tire shop nearby and see if they could scan the sensors and help me fix the problem.

Also will I need to recalibrate anything else besides the sensors, like the odometer? I read that a lot of people use the AEV Procal. Although I don't think I need it.

So the dash doesn't read any numbers. It just gives me this symbol next to each wheel (--). And there is a yellow tpms icon that lights up on the dash while driving.

The guy I bought the wheels from said it's from a 2012 rubicon which I know isn't correct because I think I'm 2012 the rubicon had the Moab wheels.

But the wheels I bought lol brand new I'm really unsure what year jeep they're from.

Since you put on stock wheels and tires you don't have to re-calibrate. As Jeff mentioned, if the sensors aren't the correct frequency they won't synch. Have a tire shop scan them. The wheels in your photo look like the 13+ wheels. They'll have to be scanned at this point to troubleshoot the problem.

Yeah this dashes means the computer does not recognize the sensors. Mine did that also and I had to go to the dealer(or any tire center) to get the computer to learn the signals. They have a handheld tool for that. In my case it was not that simple given where the sensors are located in hutchinsons I had to provide the hexadecimal codes.

I'm having the same issue. I had custom wheels put on my JKU when I purchased it and the dealer didn't put TPMS in the wheels. The stockers that were in back trunk still registered until I got home and took them out. When I restarted I had a TPMS error because no sensors were installed. I had a tire shop install the sensors from my stockers, and reprogram my computer. The fronts register but the rears never did after two trips and several "tricks" like over pressuring to 40, and swapping sides.


All TPMS systems I've ever had a hard time with are janky. I'm not an engineer but come on, it can't be that hard to make a properly working system, right?

I am tending to agree. While the used wheels you bought are new enough to have the correct frequency TPMS sensors, that's only true if they still have the factory TPMS sensors. Its always possible that the previous owner, swapped the original sensors out (to their new wheels), and put in any old junk sensor he found lying around. These could be the wrong frequency, or even have a dead battery.

Go to a tire store and have them scan the sensors and tell you what frequency they are. This will take a tire shop 2 minutes and then you'll know if you have the right frequency for your Jeep year. 2013 Jeeps and newer use 433mhz, 2012 and older use 315mhz.

You guys are awesome, thank you so much for the tips/advice I always learn so much on this forum. I'll bring my jeep to the tire shop and have them scan my wheels and see if they can fix it, if not I'll bring it to the jeep dealer.

I'll keep everyone updated, hopefully this thread helps someone else out too.

I bet you have the wrong sensors. If so, buy the correct ones on EBay or Amazon and have your tire shop install them. You'll save a hundred bucks or so over buying them from the dealer.

Different TPMS ISSUEand question here. I have snow tires on my factory 2016 JKU and purchased aftermarket sensors and had them installed. My system only reads the front 2 wheels. I swapped the fronts with rears hoping this may help all 4 show up. Now only fronts are reading while the rears still blank while they were reading properly When they were previously mounted up front.

Any thoughts or ideas?

I'll ask the obvious question, have you drove at least 7 miles? The sensors self-register, but it can take up to 7 miles for it to happen.

If that's not it, all I can think of is that the rear sensor reader isn't working. That could be why any pair of rear wheels can't be read, even those that worked when up front.
