If the light is solid, you have a low pressure tire (or the "wrong" frequency sensor). If the light is flashing, you have a bad sensor.
I've heard/read a lot of conflicting info on TPMS. Jeep changed type in 10 or 11 from the metal stem to the rubber stem sensors.
So there are two types of sensors in JKS, the older metal (gray) valve stemmed sensors and the newer black rubber stemmed sensors. They supposedly communicate on a different frequency.
Any tire shop can ping each sensor to check if it is working.
Double check the pressures and keep driving for a while, maybe the computer will eventually find all 5.
You may need to have a dealer STAR scan the rig to recognize the new sensor frequency (if that is the problem).
Did your old wheels work on the rig that they ended up on?
(Sometimes sensors are sold in "test" mode and driving around will let the computer sniff them out. Others must be activated by a scanner.)

I just had the newer, black, rubber valve stems installed on my new rims for my 09. Long story short, the new rims are black and I didn't want those ugly gray valve stems, so Discount Tire installed new black ones and my light never came on.
Not trying to contradict you, but the black stems are living in peace and harmony with my 09's computer :-)
