Maintaining proper tire pressure is crucial for vehicle safety, fuel efficiency, and tire longevity. The Tire Pressure Monitoring System (TPMS) sensor plays a vital role by continuously monitoring tire pressure and alerting you when it drops below the recommended level. Over time, TPMS sensors can fail due to battery depletion or damage, necessitating replacement. This comprehensive guide will walk you through the process of replacing a tire pressure sensor yourself, saving you time and money.
