2018 Subaru WRX Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) in the 2018 Subaru WRX is designed to alert drivers when tire pressure is too low. However, there are times when the TPMS light may flash or remain on even after correcting the tire pressure. Resetting the tire pressure sensor is essential to ensure the system functions correctly.
Steps to Reset the Tire Pressure Sensor
- Ensure that all tires are inflated to the recommended pressure levels as specified in the owner’s manual.
- Turn the ignition to the “ON” position without starting the engine.
- Locate the TPMS reset button, usually found beneath the steering wheel or near the fuse box.
- 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 Issues
If the TPMS light continues to flash after resetting, it may indicate a deeper issue. Here are some potential causes:
| Issue | Description |
|---|---|
| Faulty TPMS Sensor | The sensor may be malfunctioning and needs replacement. |
| Battery Failure | Some sensors have batteries that can fail, requiring replacement of the entire sensor. |
| Improper Installation | If tires were recently installed, the sensors may not have been properly calibrated. |
Common Signs of TPMS Problems
- TPMS light remains on after tire pressure adjustment.
- Flashing TPMS light indicates a malfunction.
- Inconsistent readings from the tire pressure gauge.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance and safety of your vehicle. For the 2018 Subaru WRX, correct tire pressure ensures optimal handling, traction, and fuel efficiency. Under-inflated tires can lead to increased tire wear, reduced fuel economy, and compromised safety. Conversely, over-inflated tires can result in a harsher ride and decreased traction.
Benefits of Proper Tire Pressure
- Improved Safety: Proper tire pressure enhances vehicle stability and reduces the risk of blowouts.
- Better Fuel Efficiency: Correctly inflated tires can improve fuel economy by reducing rolling resistance.
- Extended Tire Life: Maintaining the recommended pressure helps prevent uneven tire wear, prolonging tire lifespan.
- Enhanced Performance: Proper tire pressure ensures optimal handling and responsiveness, crucial for performance vehicles like the WRX.
How to Check Tire Pressure
Checking tire pressure is a simple yet essential task. Follow these steps for accurate readings:
- Purchase a reliable tire pressure gauge if you don’t already have one.
- Ensure tires are cold, ideally checking them in the morning before driving.
- Remove the valve cap from the tire you wish to check.
- Press the tire pressure gauge onto the valve stem firmly to get a reading.
- Note the PSI reading and compare it to the recommended pressure found in the owner’s manual or on the driver’s side door jamb.
- Replace the valve cap securely after checking.
Useful Tips for Maintaining Tire Pressure
To keep your tires in optimal condition, consider the following tips:
- Check tire pressure at least once a month and before long trips.
- Inspect tires for signs of wear, such as uneven tread or cracks.
- Use a digital gauge for more accurate readings compared to analog gauges.
- Keep a portable air compressor in your vehicle for quick adjustments.
- Be aware of temperature changes; tire pressure can drop in colder weather.
- Rotate tires regularly to ensure even wear and maintain performance.
