What is included in a Tire Pressure Monitoring System?

A typical tire pressure monitoring system (TPMS) consists of several components that work together to monitor and alert the driver to the tire pressure. Here are the main components of a TPMS:

1. Tire Pressure Sensors: These are small electronic devices mounted on each tire (usually inside the tire or attached to the valve stem) that measure the air pressure and temperature of the tire. The sensors transmit this data wirelessly to the TPMS control module.
2. TPMS Control Module: This module receives the tire pressure and temperature data from the sensors. It processes the information and determines if any tire's pressure is outside the recommended range. If an issue is detected, it triggers a warning signal or indicator to alert the driver.
3. Receiver/Display Unit: This component receives the warning signals from the TPMS control module and displays them to the driver. It can be integrated into the vehicle's instrument cluster, dashboard display, or as a standalone display unit.
4. Warning Indicators: These are visual or audible alerts that inform the driver about low tire pressure or other tire-related issues. Common warning indicators include a dashboard light, a display message, or a sound signal.
5. Wiring and Communication System: The TPMS components are connected through wiring and communication channels to exchange data. The sensors transmit the data wirelessly to the control module, while the control module communicates with the receiver/display unit to relay warning signals.

It's important to note that TPMS components can vary between different vehicle models and manufacturers. Some advanced TPMS systems may also include additional features like individual tire pressure readings, tire rotation monitoring, or integration with other vehicle safety systems.
