Understanding tire pressure sensor
A tire pressure sensor is a crucial component of modern vehicles, including Ford models, designed to monitor the air pressure in each tire. This sensor plays a vital role in maintaining optimal tire pressure, enhancing safety and improving fuel efficiency.
These sensors are part of the Tire Pressure Monitoring System (TPMS) and alert the driver when a tire is under-inflated, which can lead to various issues such as tire wear, reduced fuel economy, and even accidents. Most modern vehicles utilize indirect or direct TPMS technology:
- Direct TPMS: Uses individual sensors mounted on each tire to measure the tire pressure directly.
- Indirect TPMS: Monitors tire pressure indirectly through the vehicle’s ABS (Anti-lock Braking System) by assessing wheel speed and can detect low tire pressure by changes in wheel rotation.
When a tire pressure sensor fault occurs, it can lead to warning lights illuminating on the dashboard. Understanding how these sensors function can help you identify issues before they become serious:
