Frequently Asked Questions
Can a tire shop damage a TPMS sensor?
Yes. The TPMS sensor is mounted to the inside of the wheel, and improper tire mounting or dismounting can crack the sensor housing or break the valve stem, damaging the sensor.
Do I need a TPMS tool for sensor relearn?
Some vehicles allow manual relearn through a button sequence or driving procedure. Others require a TPMS activation tool to trigger each sensor and register it with the module.
Can I use any TPMS sensor as a replacement?
You must use a sensor compatible with your vehicle. Universal programmable sensors are available that can be programmed to match your vehicle protocol, but OEM sensors are always the safest choice.
