TPMS--2013 Sierra

[rleyland]

I have a 2013 Sierra Z71 with factory 18" wheels. Over the past month or so, at times I'm getting TPMS errors. When in first started, it appeared both passenger wheels were at fault because you would navigate to the wheel menu on the dash and both passenger wheels would have a dash where the pressure would be. It's had the error for every wheel with the exception of the drivers front wheel. This isn't consistent, but happens from time to time. Still original tires with 31k miles. Thanks,

If the sensors are as old as the vehicle, they need to be replaced, the sensor has a battery, and that is what (over time) goes bad. BOSCH makes a great and affordable replacement. The sensors are @ 315 mHz
