Recently got the Tire sensor light blinking and stay on after engineer started, mine is 2007 RX 350, have Costco changed the tire sensors on all wheels, but the light is still on, does any one know what could be the issue, and how to resolve it?

Thanks,

Shaun

You have to register the sensors with the ecu.
These vehicles allow for registration of 2 sets of sensors. Costco registration tool (hand held device) wont allow you to overwrite the original sensors that are written into the ecu; but Costco registration tool can get the 2nd set registered.
To do this, look under passenger glove box, there is a small button there that is pushed in for sensor 1 and pushed out for sensor 2 or something like that. Look in you manual.
Set this button to sensor 2 and have Costco try to register again with their tool.

If you have a copy of Techstream and a VCI cable then you can set the sensors yourself. See link
