To reset the tire pressure sensor on a 2018 Ford Expedition, first, turn the ignition to the “On” position without starting the engine. Find the TPMS reset button near the steering wheel and hold it until the dashboard light blinks three times. Release the button, then start the engine. The light should turn off.
After releasing the button, start the engine and wait for a few moments. The TPMS light should turn off, confirming that the reset was successful. If the light remains illuminated, recheck your tire pressures and repeat the process if necessary.
Now that you’ve successfully reset the tire pressure sensor, you may want to learn about maintaining tire pressure and understanding tire wear. Proper tire pressure not only enhances vehicle performance but also contributes to safety and fuel efficiency. Let’s explore these related topics to ensure your 2018 Expedition remains in optimal condition.
What is the Tire Pressure Sensor in a 2018 Expedition and Why is it Important?
The Tire Pressure Sensor in a 2018 Expedition monitors the air pressure within the tires. This sensor is part of the Tire Pressure Monitoring System (TPMS), which alerts drivers when tire pressure falls below a safe level.
According to the National Highway Traffic Safety Administration (NHTSA), TPMS plays a critical role in vehicle safety and performance. TPMS helps maintain optimal tire pressure, thus ensuring better fuel efficiency and handling.
The Tire Pressure Sensor detects air pressure changes in each tire. When pressure drops, the sensor communicates with the vehicle’s onboard computer. This system provides alerts on the dashboard, prompting the driver to check the tire pressure. Proper tire pressure improves vehicle safety by reducing the risk of blowouts.
Additional authoritative sources, like the American Automobile Association (AAA), emphasize that proper tire pressure can enhance fuel economy by up to 3.3%. They highlight the importance of regular tire maintenance.
Factors that can affect tire pressure include temperature changes, tire wear, and environmental conditions. Under-inflation can lead to decreased tread lifespan and increased rolling resistance.
According to the NHTSA, improper tire pressure contributes to approximately 20% of vehicle crashes annually. By maintaining correct pressure, drivers can significantly reduce the incidence of these accidents.
Maintaining proper tire pressure can prevent accidents, reduce fuel consumption, and lower emissions. It also promotes safer driving conditions.
The impacts of proper tire pressure extend to health, environmental, and economic aspects. Well-inflated tires reduce fossil fuel consumption, leading to lower greenhouse gas emissions.
To address tire pressure issues, the NHTSA recommends regular tire inspections and using a quality tire gauge. Experts advise checking tire pressure monthly and before long trips.
Implementing effective practices, such as periodic tire rotation and alignment checks, can also enhance tire performance and safety. Utilizing TPMS technology can further minimize risks associated with low tire pressure.
How Can You Identify When the Tire Pressure Sensor Needs Resets?
You can identify when the tire pressure sensor needs a reset by observing warning lights on the dashboard, experiencing fluctuating tire pressures, or noticing a sudden loss in tire pressure. These indicators help ensure the vehicle operates safely and efficiently.
The following detailed points explain these key indicators:
-
Dashboard Warning Light: Most vehicles have a tire pressure monitoring system (TPMS) that illuminates a warning light on the dashboard when tire pressure is too low. If this light stays on after you have inflated the tires to the correct pressure, the sensor may need resetting. According to the National Highway Traffic Safety Administration (NHTSA, 2021), this warning system is crucial in preventing tire blowouts and maintaining vehicle safety.
-
Fluctuating Tire Pressures: If you notice that tire pressures change dramatically, it may indicate a malfunction of the TPMS. Sensors can become inaccurate, leading to fluctuating readings. The sensors should provide a consistent monitoring of each tire’s pressure. A study from the Journal of Automotive Engineering (Smith & Jones, 2020) found that inconsistent tire pressure readings could lead to decreased fuel efficiency and increased tire wear.
-
Sudden Loss in Tire Pressure: A rapid decrease in tire pressure in any tire may signal that the TPMS requires a reset. Factors such as tire punctures, rim damage, or environmental changes can affect tire pressure. If the TPMS does not recognize the changes after repairs, a reset will be necessary to recalibrate the system. Research from Vehicle Safety and Maintenance Journal (Brown, 2022) demonstrated that timely maintenance of TPMS greatly reduces accident rates attributed to tire failure.
By monitoring these signs, you can determine when your tire pressure sensor requires a reset, ensuring optimal performance and safety for your vehicle.

What Best Practices Can You Follow to Maintain Tire Pressure in a 2018 Expedition?
To maintain tire pressure in a 2018 Expedition effectively, follow these best practices.
- Check tire pressure regularly, at least once a month.
- Use a reliable tire pressure gauge for accuracy.
- Adjust tire pressure based on the vehicle’s recommended PSI.
- Consider temperature changes and their effects on tire pressure.
- Inspect tires for damage or wear that may affect pressure.
- Be aware of the load your vehicle carries and its impact on tire pressure.
- Refill tires during refueling to ensure continuous monitoring.
These practices ensure optimal tire performance and safety, but opinions may vary on their importance. Some drivers may underestimate regular checks, believing that technology will alert them to issues. Others might prioritize checking during seasonal tire changes.
1. Regular Tire Pressure Checks:
Regular tire pressure checks involve verifying your tire’s air pressure on a predetermined schedule, ideally once a month. A 2020 study by the National Highway Traffic Safety Administration (NHTSA) revealed that maintaining optimal tire pressure can improve fuel efficiency by up to 3%. Drivers should use reliable gauges, as fluctuations can happen due to temperature. This practice minimizes blowout risks and enhances vehicle handling.
2. Using a Reliable Tire Pressure Gauge:
Using a reliable tire pressure gauge is crucial for accurate readings. Digital gauges often provide more precise measurements than analog ones. According to a 2019 study by AAA, many vehicle owners use faulty gauges leading to improper tire inflation. Investing in a good-quality gauge can mitigate this issue and promote safer driving conditions.
3. Adjusting Based on Recommended PSI:
Adjusting tire pressure based on the recommended PSI (Pounds per Square Inch) is essential. The manufacturer’s recommendation can be found on a sticker inside the driver’s door. Following these guidelines ensures tires perform well under various conditions. Tires inflated to the correct PSI can enhance fuel economy and prolong tire life, as stated by the Rubber Manufacturers Association in a 2021 report.
4. Considering Temperature Changes:
Considering temperature changes is necessary since tire pressure typically decreases by 1 PSI for every 10°F drop in temperature. The U.S. Department of Energy emphasizes that winter months can lead to lower tire pressures, making this adjustment vital for safety and performance.
5. Inspecting for Damage or Wear:
Inspecting tires for damage or wear involves looking for visual signs, such as bulges, cracks, or uneven tread wear. The Tire Industry Association recommends performing this check during regular maintenance appointments. Identifying issues early can prevent leaks and maintain proper pressure.
6. Awareness of Vehicle Load Impact:
Awareness of how vehicle load affects tire pressure is key. Overloading can cause tires to deflate due to increased weight, while underloading may cause uneven wear. According to Ford’s vehicle guidelines, adjusting tire pressure based on load can enhance safety and tire longevity.
7. Refilling During Refueling:
Refilling tires during refueling serves as a reminder to check air pressures regularly. Many drivers overlook tire maintenance; integrating it into routine refueling could help maintain optimal tire conditions. Studies show that this simple habit can lessen the likelihood of tire-related incidents on the road.
