Understanding TPMS and Its Role in Safe, Efficient Driving

The Tire Pressure Monitoring System (TPMS) alerts you when one or more tires are underinflated, helping prevent unsafe driving conditions, excessive tire wear, and reduced fuel economy.
When a TPMS warning light appears, it indicates that the tire pressure or system performance requires attention.

This MAP educational video explains how TPMS works, what causes warning lights, and why proper maintenance is essential for accurate tire pressure monitoring.

At the Motorist Assurance Program (MAP), we provide motorists with clear, unbiased information to help them understand critical safety systems.

By learning how TPMS sensors, valves, and control modules operate, drivers can make informed decisions when discussing tire service or diagnostic needs with a professional.

Common reasons for TPMS alerts include low tire pressure, seasonal temperature changes, sensor battery failure, valve stem damage, or system communication issues.
Because these symptoms may also be linked to tire damage or leaks, proper inspection is necessary to determine the actual cause.

After watching this video, consider consulting a MAP-qualified service facility if your TPMS light stays on or your tire pressure readings appear inconsistent.
