TPS Light still on after checking tires

All my tires are topped off to specs. Yes the light wont go off on the TPS.
Is there a reset that I am forgetting to check? This is the first time in 2 years I have had this go on.

Yep......You have to drive it. As I understand it, the Subaru system checks tire rotations speeds against each other before it will reset the light.
BMW uses a system like that, but I'm pretty sure there are transmitters at each wheel in Subarus.

Yes, Subaru uses sensors......But one system does not preclude the other. All the ECU has to see is the speed reading from all 4 ABS sensors to ascertain whether all are within parameters.

Why else would you have to drive the car to get it to reset?
One doesn't have to preclude the other... It just happens to in this case.
