2018 Toyota Corolla iM Tire Pressure Sensor Reset
When the tire pressure monitoring system (TPMS) light flashes on your 2018 Toyota Corolla iM, it typically indicates an issue with the tire pressure or the sensor itself. Resetting the tire pressure sensor is a straightforward process that can help ensure that your vehicle’s monitoring system is functioning correctly. Follow the steps below to reset the TPMS light.
Steps to Reset the Tire Pressure Sensor
- Check Tire Pressure: Before resetting the sensor, ensure that all tires are inflated to the recommended pressure levels as indicated in the owner’s manual.
- Turn on the Ignition: Insert the key into the ignition and turn it to the “On” position without starting the engine.
- Locate the TPMS Reset Button: The reset button is usually located beneath the steering wheel or near the fuse box.
- 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. The TPMS light should turn off after a few minutes of driving.
Tire Pressure Monitoring System Light Flashing
If the TPMS light continues to flash or remains on after following the reset procedure, it may indicate a malfunction in the system. Here are common reasons for a flashing TPMS light:
| Issue | Description |
|---|---|
| Low Tire Pressure | One or more tires may be under-inflated, triggering the warning light. |
| Faulty TPMS Sensor | The sensor may be damaged or malfunctioning, requiring replacement. |
| Dead Battery in Sensor | The battery in the tire pressure sensor may be dead and needs to be replaced. |
| Temperature Changes | Significant temperature changes can affect tire pressure, leading to a warning light. |
What to Do Next
If the TPMS light remains illuminated after attempting to reset it, consider the following actions:
- Inspect all tires for visible damage or punctures.
- Check the tire pressure using a reliable gauge.
- Visit a qualified mechanic or dealership for a diagnostic check.
- Replace any faulty sensors or batteries as needed.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall performance, safety, and longevity of your vehicle. Under-inflated or over-inflated tires can lead to various issues, from reduced fuel efficiency to compromised handling. Regularly checking and adjusting tire pressure can prevent these problems and enhance your driving experience.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Correct tire pressure reduces rolling resistance, which can lead to better fuel economy.
- Enhanced Safety: Properly inflated tires provide better traction, reducing the risk of accidents.
- Extended Tire Life: Maintaining the right pressure helps prevent uneven wear, prolonging the life of your tires.
- Better Handling: Proper inflation improves vehicle handling, ensuring a smoother ride and better responsiveness.
How to Check Tire Pressure
Checking tire pressure is a simple task that can be done at home with a few tools. Follow these steps to ensure your tires are properly inflated:
- Gather Necessary Tools: You will need a tire pressure gauge and an air compressor if adjustments are needed.
- Check When Tires Are Cold: Tire pressure should be checked when the tires are cold, ideally before driving or after the vehicle has been parked for at least three hours.
- Remove Valve Stem Caps: Unscrew the valve stem caps from each tire.
- Press Gauge onto Valve Stem: Firmly press the tire pressure gauge onto the valve stem until you hear a hissing sound stop. Read the pressure displayed on the gauge.
- Compare with Recommended Pressure: Refer to the owner’s manual or the sticker on the driver’s side door jamb for the recommended tire pressure.
- Adjust Pressure as Needed: If the pressure is too low, use an air compressor to inflate the tire. If it’s too high, release some air until it reaches the recommended level.
- Replace Valve Stem Caps: After checking and adjusting the pressure, securely replace the valve stem caps.
Useful Tips for Maintaining Tire Pressure
- Check tire pressure at least once a month and before long trips.
- Invest in a quality tire pressure gauge for accurate readings.
- Be aware of seasonal changes, as temperature fluctuations can affect tire pressure.
- Keep an eye out for uneven tire wear, which may indicate a pressure issue.
- Consider using nitrogen instead of air for inflation, as it can help maintain pressure longer.
