Tire Pressure Indicator Light
2007 Lexus RX350 - Tire pressure light stays on; have adjusted the tire pressure and followed the instructions meticulously and several times to no avail. Thoughts?

FWIW Professional level tools go from some $1400 and up.
As I understand it (Doc back me up on this), it's not just absolute pressure but variation between tires that might trigger the light?

Without seeing this in person and accessing the TPMS control module for codes and data there isn't much else that we can do here. It's possible that there is an issue with the system and it cannot receive the sensors radio communication. Unless your tool displays the battery health you really don't know if all of the sensors are sending a strong enough signal for the receiver to pick up.
