Low Tire Pressure Warning

Hello! I have a 2011 Jeep Wrangler. Haven't had an issue since I got it, until earlier this month. I was coming up on oil change time and noticed that my low pressure tire warning also came on. I had the guys check it when they changed the oil, no issue so they got it reset/turned off.

Come ahead a week. I get in the Jeep this morning and head off and the warning is on again.

I've read a couple threads where someone's mentioned the timing seeming to be with the oil change and the answers/replys were how to reset the change oil light.

I've yet to head out on a trail that I needed to drop the pressure, so I haven't done it. The pressure is fine in the tires, but yet the light loves to warn me.

Anyone else run across this issue with the sensors seemingly not working right, or a timing of the warning with the oil change, etc?

I can't comment specifically on the TPMS lights. However, I had my electronics go haywire one day. My windshield wipers were going on by themselves, interior light was lit, headlights on...the works with the engine running. I took it to my mechanic and they checked the battery (all good), ran codes (all good) and they didn't have a clue.

So I took it home, unplugged the battery and left it for about 10 minutes. I hooked the battery back up and all the problems were solved. Unplugging the battery allowed the computer to reset. All has been good since.

This is simply one thing you can try.

Thanks! I'll put that on the list of options

Do you have a tire pressure gauge? Check the tires just to be sure one is not leaking. What tire pressure does your door tag tell you to put in?

the other option if the tire pressure is good in all the tires is that one of the TPMS sensors are bad. there is a small battery in each TPMS sensor and when the battery goes dead its time to replace the sensor.

The TPMS is a pain. Quick fix (but costs $$): ProCal Module - Electronics - Shop By Category

I used this to drop my threshold to 24. Now it only comes on when I air down to go off road. I keep it at around 30-32 for asphalt driving.

KBWWOLF: While it's a bit of money, it looks like it'd be very handy! I'll put that on my list of items to get.

HK_Runner: The pressure is fine in the tires, as it should be. But now a year in the sensor is being goofy.

Also check the pressure on the spare, our spare was low and it solved the issue after inflating to right pressure.
