TPMS Light - Need help. Tried lots of fixes
I bought 2013 JKU for my 18 year old daughter from one of my best friends. The JKU has about 50,000 miles and was customized with a lift, 34" tires and 22" wheels. We bought a few weeks ago knowing I needed to put some new tires on it soon. My daughter put about 500 miles on it with no issues and I decided to go ahead and get the new tires before she goes off to college.
The tire pressure light on the dash came on a day or so after installing the new tires. Checked the tire pressure on all 5 tires and all was good. Took it back to the tire shop and they reset the light (yes they were surprised they could reset it because they even knew that normally you have to drive it for 10 minutes or so for it to reset). It stayed off for about 20 miles then was right back on. I then took it to a different tire shop (because mine was closed), they checked the sensors in all 5 tires and they all were shows the sensors were transmitting and the batteries were ok.
So this week, we were going out of town so I left it at my tire shop again and they reset the light and reprogrammed the sensors and drove it a couple of days. They thought they had it fixed all though they were puzzles why they could reset the light without driving it. I picked it up this afternoon and drove about 20 miles and the light is back on.
If this was my jeep I wouldn't worry about it but since it is my 18 year old daughters, I would really like to get it back working before she is running the roads back and forth to college.
I did buy a programmer and adjusted the psi threshold when the light should come on and that didn't help either.
Anyone seen this behavior before and have any idea what I should try to fix it?
Thanks for your help
