Resetting Tire Pressure Sensor for 2017 Ford Focus ST
The tire pressure monitoring system (TPMS) in the 2017 Ford Focus ST is designed to alert drivers when tire pressure is too low or when a tire is underinflated. If the TPMS light is flashing, it indicates that there is a malfunction or that the tire pressure needs to be reset. Knowing how to reset the tire pressure sensor is essential for maintaining proper tire pressure and ensuring your vehicle operates safely.
Steps to Reset Tire Pressure Sensor
- Check Tire Pressure: Before resetting the sensor, ensure that all tires are inflated to the recommended pressure levels.
- Turn on the Ignition: Insert the key and turn the ignition to the “On” position without starting the engine.
- Locate the TPMS Reset Button: This button is typically found under the steering wheel or in the glove compartment.
- Press and Hold the Reset Button: Hold the button until the TPMS light blinks three times, then release it.
- Start the Engine: Turn the ignition off and then start the engine to complete the reset process.
- Drive the Vehicle: Drive for a few minutes to allow the system to recalibrate.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash after following the reset procedure, it may indicate a more serious issue. Below are common reasons for a flashing TPMS light:
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires may be significantly underinflated. |
| Faulty Sensor | A malfunctioning sensor may need to be replaced. |
| Battery Issues | The battery in one or more TPMS sensors may be dead. |
| System Malfunction | There may be an electrical issue within the TPMS. |
What to Do If the Light Remains On
If the TPMS light remains illuminated after a reset, consider the following steps:
- Recheck Tire Pressures: Ensure all tires, including the spare, are properly inflated.
- Inspect for Damage: Look for any visible damage or punctures on the tires.
- Visit a Professional: If issues persist, consult with a qualified technician for a thorough inspection.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance and safety of your vehicle. For the 2017 Ford Focus ST, correct tire pressure enhances handling, fuel efficiency, and tire longevity. Under-inflated tires can lead to increased rolling resistance, which negatively impacts fuel economy and can cause excessive wear on the tires. Conversely, over-inflated tires can reduce traction and lead to a harsher ride.
Proper tire pressure also plays a vital role in braking performance. When tires are inflated to the recommended levels, they provide optimal contact with the road, improving grip during braking and cornering. Additionally, maintaining the right pressure helps prevent blowouts and other tire-related issues that could compromise safety on the road.
How to Check Tire Pressure
Checking tire pressure is a straightforward process that should be done regularly. Here’s how to do it:
- Gather Your Tools: You will need a reliable tire pressure gauge. Digital gauges are often more accurate than manual ones.
- Check When Tires Are Cold: Measure tire pressure in the morning or after the vehicle has been parked for several hours. This ensures that the tires are at a stable temperature.
- Remove Valve Cap: Unscrew the valve cap from the tire you want to check.
- Press Gauge onto Valve: Firmly press the tire pressure gauge onto the valve stem. Ensure a good seal to get an accurate reading.
- Read the Pressure: Check the gauge to see the current tire pressure. Compare it to the recommended pressure found on the driver’s side door jamb.
- Repeat for All Tires: Perform the same steps for each tire, including the spare.
Useful Tips for Maintaining Tire Pressure
To ensure your tires remain properly inflated, consider the following tips:
- Check Monthly: Make it a habit to check tire pressure at least once a month and before long trips.
- Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes. For every 10°F drop in temperature, tire pressure can decrease by 1 PSI.
- Inspect for Wear: Regularly inspect tires for signs of uneven wear, which can indicate improper inflation or alignment issues.
- Use a Quality Gauge: Invest in a quality tire pressure gauge for accurate readings. Digital gauges are often easier to read.
- Don’t Forget the Spare: Check the spare tire as well; it’s often overlooked but can be critical in emergencies.
By following these guidelines, you can maintain proper tire pressure, enhancing the performance and safety of your 2017 Ford Focus ST. Regular checks and adjustments will ensure that your tires last longer and perform optimally on the road.
