Hi. I have a 2008 CX-9 Grand Touring, original owner, 145K miles with 20" wheels. The TPMS light is on and after checking, all of my tire pressures are fine. I have a Computer Reader and when I check codes it says something like Left Rear Sensor not responding. I reset the light hoping that might take care of it but it is back on. Mazda has always done all my service including installing new tires. Do they service the sensors when changing tires or can I assume that the sensors, batteries (if not replaceable) are all factory and never been touched making them 13 years old? They have never mentioned it nor have I have ever seen it listed on a receipt. Depending on cost, not sure if I want to replace them. I assume I would want to do them all and I will probably be getting rid of it in the next year. If not, is there a way to disable the light?
Thank You.
Thank You.
