2019 Subaru Impreza Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) in the 2019 Subaru Impreza is designed to alert drivers when tire pressure is too low or if there is a malfunction in the system. If the TPMS light is flashing, it indicates a problem that needs attention. Resetting the tire pressure sensor is essential to ensure that the system functions correctly and provides accurate readings.
To reset the tire pressure sensor, follow these steps:
Steps to Reset the Tire Pressure Sensor
- Check and adjust the tire pressures to the recommended levels as specified in the tire pressure table.
- Turn the ignition key to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or near the driver’s side dashboard.
- Press and hold the TPMS reset button until the TPMS light blinks three times, then release it.
- Start the engine and drive the vehicle for about 10 minutes to allow the system to recalibrate.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash after resetting, it may indicate a more significant issue. Below are potential causes of a flashing TPMS light:
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires are below the recommended pressure. |
| Faulty Sensor | A tire pressure sensor may be malfunctioning or damaged. |
| TPMS Malfunction | The TPMS itself may have a fault that requires diagnosis. |
| Temperature Changes | Significant temperature fluctuations can affect tire pressure and trigger the light. |
What to Do If the Light Remains On
If the TPMS light remains illuminated after following the reset procedure, consider these actions:
- Inspect all tires for visible damage or punctures.
- Verify that the tire pressures are set correctly.
- Consult a professional mechanic or Subaru dealership for further diagnosis.
Maintaining Proper Tire Pressure
Proper tire pressure is crucial for the overall performance, safety, and efficiency of your vehicle. For the 2019 Subaru Impreza, maintaining the recommended tire pressure can lead to several benefits. When tires are inflated to the correct pressure, they provide better traction, improved fuel economy, and enhanced handling. Conversely, under-inflated or over-inflated tires can lead to reduced performance, increased tire wear, and a higher risk of blowouts.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Correct tire pressure helps reduce rolling resistance, which can enhance fuel economy.
- Extended Tire Life: Maintaining proper pressure reduces uneven wear, prolonging the lifespan of your tires.
- Enhanced Safety: Properly inflated tires improve vehicle handling and braking performance, reducing the likelihood of accidents.
- Better Ride Comfort: Correct tire pressure contributes to a smoother ride by absorbing road imperfections more effectively.
How to Check Tire Pressure
Checking the tire pressure of your 2019 Subaru Impreza is a straightforward process. Follow these steps to ensure your tires are properly inflated:
- Get a reliable tire pressure gauge. Digital gauges are often more accurate and easier to read than analog ones.
- Ensure that the tires are cold. Tire pressure should be checked when the tires have not been driven for at least three hours.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge onto the valve stem and take the reading.
- Compare the reading to the recommended pressure found in the owner’s manual or on the driver’s side door jamb.
- If the pressure is too low, add air until it reaches the recommended level. If it’s too high, release some air until it’s correct.
- Replace the valve cap securely after checking.
- Repeat the process for all tires, including the spare if applicable.
Useful Tips for Tire Maintenance
To ensure optimal tire performance and longevity, consider the following tips:
- Check tire pressure at least once a month and before long trips.
- Inspect tires for signs of wear or damage, such as cracks, bulges, or uneven tread wear.
- Rotate your tires every 5,000 to 7,500 miles to promote even wear.
- Align your wheels if you notice your vehicle pulling to one side or if the steering wheel is off-center.
- Keep a portable air compressor in your vehicle for emergencies.
By adhering to these practices, you can maximize the performance and safety of your 2019 Subaru Impreza while ensuring a comfortable driving experience.
