Having what seems to be a common issue with the TPMS on my 2004 GC Overland. Have searched and reviewed the many posts here and elsewhere, but the problem resolution still seems elusive.
I started getting the chimes and the "TIRE PRESSURE SENSOR BAD/MISSING" a week ago. The tire pressure was fine. Took to dealer for other issue and asked them to look at it. They found spare was at 25 psi and filled and retrained all tires. When I pick it up, the warning is still there and chimes sound. They take Jeep back in to shop, hook up to scanner and it shows no faults. They then get another scanner and same result.
At this point, I guess it could be a bad EVIC, but it works fine otherwise, showing correct pressure in tires, etc. Other option is to replace the sensors, which at 8+ years are reaching their life, but no warnings from system yet.
