IMPORTANT
Just got back from Discount Tire and finally had my TPMS issue fixed.
Backtrack: A few months ago the light came on randomly while driving. Tires were fine though so I ignored the light until the next trip to discount tire. Well the kid there hooked up the TPMS handheld sensor to the computer and could read all of my sensors. They were all working fine. So he tried to reprogram and reset the TPMS computer. After that failed, he told me the TPMS computer was probably bad and he couldn't fix it. So I just ignored it.
Fast forward to today and I went to a different discount tire and I told the kid there to ignore the light. He said "why? Let's fix this today if all of your sensors are working". Well while he was scanning my sensors into the handheld computer, I realized he didn't scan my spare tire. I got him to scan my spare tire and the he reprogrammed my TPMS computer and then light turned off.
Basically,
MAKE SURE THEY SCAN YOUR SPARE TIRE.
That is all.
I wonder how many people are driving around with working sensors and computers and have this same issue?
