In the next section, we will explore common TPMS issues and solutions for the Ford Expedition, helping you maintain your vehicle’s efficiency even further.
What Is the Tire Pressure Monitoring System (TPMS) in the Ford Expedition?
The Tire Pressure Monitoring System (TPMS) in the Ford Expedition is an electronic system that continuously monitors the air pressure in each tire. It alerts the driver when tire pressure falls below safe levels, ensuring optimal vehicle performance and safety.
According to the National Highway Traffic Safety Administration (NHTSA), TPMS enhances vehicle safety by decreasing the likelihood of tire blowouts caused by under-inflation. The NHTSA mandates TPMS for all passenger vehicles manufactured after 2007.
TPMS operates through sensors in each tire that detect pressure changes. When a tire’s pressure drops, the system triggers a warning light on the dashboard. This alert allows drivers to address tire issues promptly, contributing to improved fuel efficiency and better handling.
The Society of Automotive Engineers (SAE) defines TPMS as a system that automatically monitors the air pressure in tires and helps maintain proper inflation through real-time alerts. Two types of TPMS exist: direct and indirect. Direct measures pressure via sensors, while indirect uses ABS signals to estimate tire pressure.
Causes of TPMS alerts can include temperature fluctuations, punctures, and slow leaks. Under-inflated tires can lead to increased tire wear and reduced fuel economy.
Data from the NHTSA indicates that under-inflation contributes to 600 fatalities and more than 33,000 injuries annually in the U.S. Properly inflated tires can improve fuel efficiency by up to 3%.
Improper tire inflation can result in accidents, increased fuel consumption, and higher emissions, thus impacting public safety, environment, and economies.
For instance, a vehicle with under-inflated tires may consume an additional $300 in fuel annually. Investing in TPMS can reduce these costs substantially.
To mitigate tire pressure issues, the NHTSA recommends regular tire pressure checks along with using TPMS systems. Many driving manuals also advise drivers to visualize tire pressure readings.
Effective strategies to maintain tire pressure include automatic monitoring systems, driver education regarding tire upkeep, and the use of tire pressure gauges. Regular inspections can also help prevent tire-related incidents.
