I have a 2011 wrangler and the low tires pressure light has been going off since month 1. My dealership garage says they've replaced all of the sensors, but it still goes off...anyone else have this issue?
Buy a YJ or TJ and never worry about this again.
Seriously though, try rotating your tires front to rear. The pressure sensor really reads RPM, not pressure, if the problem goes away tell the dealer what you did. That will help them track it down.
BTW; Are your tires the same size?
My 07 Laredo and my 08 srt8 both have restarted tpms sensors ever since I bought the jeeps they have had issues. I just recently decided to switch all tpms sensor to the new style sensor made by vdo. (aluminum valve stems) when I replaced them all I had to do was disconnect the iod fuze located under the hood #27 reconnected after 10 min and the wcm will clear any past codes. Have psi at 36 havnt had a problem with my system for 300 miles. Keep in mind jeep do not have a set procedure for resetting the tpms sensors besides just driving the car for 10 min above 20 mph. The premium tpms systems require a magnet to wake the sensors up. Hope this helps.
TPS (or TPMS) are a brilliant convenience for those who use their cars as drivers and don't want to have to worry about all of the safety checks that most don't have the time for. Believe it or not people do pay attention to that light when it comes on, and come to fill their tires up. It's on a very short list of government mandated safety devices that I actually advocate for.
Whoever said it works off of tire RPM is only partially correct. The direct system actually employs a pressure sensor inside of the tire that transmits a live feed to the vehicles computer, based off of the actual pressure inside of the tire.
An indirect pressure sensor uses RPM sensors to detect slight variances in angular velocity from an under-inflated tire, sensors not located inside of the tire. The vast majority of vehicles out there today employ a direct system, the indirect system is fading away.
If the light is still on there may be a few things at play:
1. Your tires are actually under-inflated.
2. Your pressure sensors are not set for the tires pressure (I.E. from bigger tires that run a lower pressure- it takes 3PSI difference to trip the sensor).
3. Faulty pressure sensing system, in which case the light would actually blink.
4. You need to manually reset the tire pressure light VIA button, normally located on the bottom of the dash panel.
Most of the time you need to overinflated your ties by about 5 psi and then back down. I believe they trigger around 32 to 36 psi.
I like the tpms system, it's shown me my last 4 low tires before it ever became an issue. If you don't like it, get a procal or other module and turn it off.
The current jeep system has nothing to do with rpm. It's direct pressure reading.

I bought a 2015 Wrangler unlimited. Had the dealership install a 3"lift and then added some 20x12.50 Fuels and 35x12.5 open country tires. I had them switch over the sensors. I have taken my jeep in 7 times already over the past 2 months (only had the dam thing 3 months), they have reset sensors, replaced two sets of sensors and the light continues to appear after I drive it for 3-4 days. This last time I picked it up after they had it two days and the light came on 15 minutes after I left the dealership! Now the manager is telling me they want to put regular wheels on it for a week to see if the light comes on. If it doesn't its my wheels and tire set-up, which he then says they will not be able to do anything else about. He said the Chrysler people are telling him that he new sensors don't sit properly on my wheels and therefore create the issue. I told him that wasn't good enough. he mentioned the after market kit to turn of the light, but I told him that would be just what they want so my factory warranty becomes void. anyone else having issues like this? Anyone gone up the chain with Chrysler. I certainly don't think i'm the first person to change to a 3" lift and 35" tires! such bull****. Please help me or advise me on how to handle this situation. This is my first brand new vehicle ever and I already regret it. Thanks Mark.
