2018 Subaru Impreza Tire Pressure Sensor Reset

The tire pressure monitoring system (TPMS) in the 2018 Subaru Impreza is designed to alert drivers when tire pressure is too low or if there is a malfunction. If the TPMS light is flashing, it indicates that the system needs attention, often due to a tire pressure issue or a need for sensor recalibration. Knowing how to reset the tire pressure sensor is crucial for maintaining vehicle safety and performance.

Steps to Reset the Tire Pressure Sensor

To reset the tire pressure sensor, follow these steps:

1. Check the Tire Pressure: Ensure all tires are inflated to the recommended pressure levels as indicated in the earlier section.


2. Turn the Ignition On: Start your vehicle or turn the ignition to the “On” position without starting the engine.


3. Locate the TPMS Reset Button: This button is usually found beneath the steering wheel or on the dashboard. Refer to the owner’s manual for the exact location.


4. Press and Hold the TPMS Reset Button: Hold the button until the TPMS light blinks three times, then release it.


5. Drive the Vehicle: Take the car for a short drive (about 10 minutes) at speeds over 25 mph. This allows 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 malfunction in the system. Here are possible reasons for a flashing TPMS light:

What to Do If the Light Remains On

If the TPMS light remains illuminated or continues to flash after resetting, consider these actions:

• Recheck Tire Pressures: Verify that all tires are at the correct pressure.


• Inspect for Damage: Look for any visible damage to the tires or sensors.


• Consult a Professional: If issues persist, take the vehicle to 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. Under-inflated or over-inflated tires can lead to a range of issues, including reduced fuel efficiency, uneven tire wear, and compromised handling. In extreme cases, incorrect tire pressure can increase the risk of tire blowouts, which can be dangerous while driving.

Proper tire pressure ensures optimal contact with the road, providing better traction and stability. This is especially important in adverse weather conditions, where tire performance can significantly impact safety. Additionally, maintaining the correct tire pressure can extend the lifespan of your tires, saving you money in the long run.

How to Check Tire Pressure

Checking tire pressure is a simple process that can be done at home with a tire pressure gauge. Follow these steps to ensure your tires are properly inflated:

1. Gather Your Tools: You will need a reliable tire pressure gauge. Digital gauges are often easier to read, but analog ones work just as well.


2. Check When Tires Are Cold: Tire pressure should be checked when the tires are cold, ideally before driving or after the car has been parked for a few hours.


3. Remove Valve Cap: Unscrew the valve cap from the tire you want to check.


4. Press the Gauge: Firmly press the tire pressure gauge onto the valve stem. Ensure there is no hissing sound, which indicates air escaping.


5. Read the Pressure: Check the reading on the gauge. Compare it to the recommended pressure listed in the owner’s manual or on the driver’s side door jamb.


6. Replace the Valve Cap: After checking, replace the valve cap to prevent dirt and moisture from entering.

Useful Tips for Tire Pressure Maintenance

To ensure your tires remain in optimal condition, consider the following tips:

• Regular Checks: Check your tire pressure at least once a month and before long trips.


• Use the Right Gauge: Invest in a quality tire pressure gauge for accurate readings.


• Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes. Check pressures during seasonal transitions.


• Inspect for Damage: Regularly inspect your tires for signs of wear, punctures, or other damage that may affect pressure.


• Know the Recommended Pressure: Familiarize yourself with the recommended tire pressures for your specific trim and engine type.


• Consider a TPMS: If your vehicle is equipped with a Tire Pressure Monitoring System, pay attention to alerts and warnings.

By prioritizing proper tire pressure maintenance, you enhance your vehicle’s performance, safety, and longevity.
