Tire pressure monitors

Can putting air in your tires screw up your monitors?

My tires were all showing 26-27 lbs and my RF warning came on a few times @ 25lbs, so I aired them all to 30 lbs...Now my TPS shows nothing for any tire...I'm not getting any kind of warnings but when I check there are no readings.

I think the procedure is in the owners manual or you can do a search in the forum and there are threads that detail the correct procedure. Your will need a fairly strong magnet to do the relearn procedure. If the relearn trick doesn't work then more troubleshooting will be required. Though it would surprise me very much if the all sensors are bad. Having all sensors go bad at the same time would be so unusual that it borders on the impossible. I would suspect a communication problem if the relearn procedure doesn't work.

good luck

If putting air in tires screwed up the sensors, there wouldn't be a working set out there. Drive it and report back what happens.

Each sensor has a centrifugal switch in them which means the wheel needs to spin fast enough to activate the transmitter in each. Therefore driving it as suggested should being them to life.

Take the car for a 20 min drive. If the system detects a sensor not sending signals it turns on the "Service TPMS" message and displays XXX for the tire pressure.
