Bill Traer 0 Report post Posted June 20 I have an 08 GX470 with 113,000 miles. Tire pressure warning light came on and we filled the tires to required pressure but light won't go out, - any suggestions? Quote Share this post Link to post Share on other sites
1990LS400 122 Report post Posted June 24 If the pressure sensors are the originals, it's likely that one of their batteries has failed. If that's the case, you might as well replace all the sensors. The batteries usually aren't replaceable. Replacing the sensors will require uploading the ID codes for the new sensors to the vehicle ECU through the diagnostic port. Any tire shop can do that. I bought an inexpensive ($125) electronic tool to do it since we have multiple vehicles with both summer and winter wheels/tires. Quote Share this post Link to post Share on other sites
