This scenario may seem like an isolated incident, but it’s more common than you think. In fact, studies have shown that up to 70% of TPMS false alarms can be attributed to faulty sensors or system malfunctions. So, what’s behind these misleading readings, and how can you avoid falling victim to them?
The Anatomy of a TPMS System
A typical TPMS system consists of several key components, each playing a crucial role in monitoring tire pressure:
- Tire Pressure Sensors (TPS): These small, battery-powered devices are attached to the valve stem of each tire. They measure the air pressure and send the data to the vehicle’s onboard computer.
