• Sensors installed at the valve stem of the wheel that directly measure pressure in the tire
• A centrally located receiver and electronic control unit (ECU) that receives and processes data sent from the sensors
• A low tire pressure telltale found on the dashboard that illuminates when one or more tires are under inflated.

Because TPM sensors are housed inside of the tire, special care is needed when tires are removed and new ones installed. TPM suppliers have different methods or recommendations for how to protect the sensor during a tire change. This section is designed to help service dealerships and vehicle manufacturers to service EnTire Solution TPM sensors.
