My jeep had the low tire light come on while driving towards my oil change. It was still on after and I told the guy and he said I had to drive on it for a few minutes and it'll go off on it's own. It's been two days and it's still on. Checked tires... They're fine... What's wrong with him??
Just so you know, the update that picks up changes is not instant - that's where he is getting the 'drive it for a few minutes' detail from.
Did you check the spare as well? If you have the stock tires and programming, are all tires over 31PSI? If the answer to both is 'yes', you could have a bad TPMS sender (one for each wheel) or receiver. Oh, and I seem to recall that very high PSI will show with the same light being on - for stock I think this is over 41PSI, but I could be wrong on that figure.
One of the things I like about the EVIC vs non-EVIC is that you can see right on the dash the actual reported PSI of each tire. This means you can tell if one tire is at '0' (which likely means bad sender), all are at '0' (likely bad receiver), or just one or more are low. Additionally if none show low but the light is on, you know it is the spare that's causing the alarm condition.
I had one that dipped below 30 PSI, light came on, and I had to get the pressure above 35 PSI in order for the system to reset. It does take a minute (usually driving a few hundred feet at 15 mph and above will work).
Absolutely correct - however if the 4 displaying are not blinking or 0, and the light is on, that tells you that the computer is having some kind of a problem with the spare. Definitely easier to figure out than just the TPMS light alone and no other info from the computer.
Swapping the spare in (either because of puncture or normal rotation) does sometimes take a few start cycles for the computer to figure out where the tires are, but it's not too bad (unless you didn't know it was going to figure it out eventually)
To the OP - if you can answer this (i.e. put a tire pressure gauge on each of the tires including the spare and write down the values), it may help us help you diagnosing what's going on.
I am having the same problem. None of my tires are low but the light is on. Boosted the pressure to 35psi by my tire gauge but the light still has not gone out. Tried setting the alarm to 28psi with my Procal, didn't work, light stays on, tried turning TPSM off and light still stays on. May have to drive it for a bit longer and if it doesn't go out it's back to the dealer I guess.
My 2011 Sahara low tire light won't kick off unless I air up to 38 psi. I drive a block or so and it goes out and then I air down to 35 and it stays off.
on my '11 rubicon i had to air up to 40 psi to get the light to go out. no driving around, just aired up cycled the ignition light went off tires went back to 37psi. that was on stick tires.
Thank you very much. Filled up my tire a lot more than the oil change guy did and it turned right off. But I did just discover a screw in my tire so I'm tickled now haha when it rains it pours I guess.
Where is it exactly? My understanding is that sidewall punctures can't be repaired, but tread punctures can be.
I've had to deal with this several times - locally for me VIP/OReily's is cheaper than Goodyear ($38), but both do similar service. Both will tell you before they charge if they are able to repair the puncture. You can use a tire puncture kit, but the shops will do the repair somewhat differently (I would argue they do a better job).
The odd thing about using the procal to turn off TPMS, the indicator light goes out but every time the Jeep is started the tire diagram comes on the digital info center. It shows the four tires at 0 psi and stays on until the menu button is pushed. Not a huge deal but I'd think AEV could've done something with that too.
45 PSI is the max pressure listed on the sidewall of your tire, not the cold pressure you should be at - not going to be very comfortable ride and should throw the warning light (because it is overpressure, which is also a safety issue just as underpressure is). Drop your PSI down to 35. Tire wear and driving comfort and stability will be better. Look at the sticker on the driver side door jamb next to the latch, that shows the recommended pressure from Jeep with the stock tires. If you change to different tires (i.e. different model or size), that recommendation is irrelevant and you are on your own.
For whatever reason the light went "out" and yes it is a stiff ride....I will drop down to 35 & thanks for the reply.
