1. Understanding the Tire Pressure Monitoring System (TPMS) in Your Toyota Corolla
Do you know what the Tire Pressure Monitoring System (TPMS) does in your Toyota Corolla? The Tire Pressure Monitoring System (TPMS) in your Toyota Corolla constantly monitors the air pressure in your tires and alerts you when the pressure drops below the recommended level.
The Tire Pressure Monitoring System (TPMS) is a crucial safety feature in your Toyota Corolla designed to keep you informed about the condition of your tires. According to the National Highway Traffic Safety Administration (NHTSA), TPMS has been mandatory in all new vehicles since 2007, significantly reducing the risk of tire-related accidents. This system uses sensors in each tire to measure air pressure and sends this data to your car’s computer. When the pressure in one or more of your tires falls below a certain threshold (typically 25% below the recommended pressure), the TPMS will activate a warning light on your dashboard. This warning light usually looks like a horseshoe shape with an exclamation point inside.
Tire Pressure Monitoring System (TPMS) Display
1.1. Types of TPMS
What are the two types of TPMS? There are two main types of TPMS: direct and indirect.
- Direct TPMS: Uses pressure sensors inside each tire to directly measure tire pressure.
- Indirect TPMS: Relies on the vehicle’s anti-lock braking system (ABS) to estimate tire pressure by monitoring the rotational speed of the wheels.
Your Toyota Corolla likely uses a direct TPMS, which provides more accurate and real-time pressure readings. According to Toyota’s official website, direct TPMS helps drivers maintain optimal tire pressure, improving fuel efficiency and tire life.
1.2. Importance of Maintaining Proper Tire Pressure
Why is it important to maintain proper tire pressure? Maintaining proper tire pressure is essential for safety, fuel efficiency, and tire longevity.
Properly inflated tires provide better handling and stability, reducing the risk of accidents, especially in adverse weather conditions. Under-inflated tires can lead to:
- Reduced fuel economy
- Increased tire wear
- Poor handling
- Higher risk of tire failure
According to a study by the National Transportation Safety Board (NTSB), maintaining proper tire pressure can improve fuel efficiency by up to 3.3%. This not only saves you money at the pump but also reduces your vehicle’s emissions.
1.3. How to Find the Recommended Tire Pressure for Your Corolla
Where can you find the recommended tire pressure for your Corolla? The recommended tire pressure for your Toyota Corolla can be found on a sticker located on the driver’s side doorjamb or in your owner’s manual.
This sticker provides the ideal tire pressure for both the front and rear tires, usually measured in pounds per square inch (PSI). It’s important to note that the number on the tire sidewall is the maximum pressure, not the recommended pressure. Regularly checking and adjusting your tire pressure to the recommended PSI will ensure optimal performance and safety. Miller Toyota’s service experts recommend checking your tire pressure at least once a month and before any long trips.
2. Identifying Reasons Why Your Tire Pressure Light Is On
What are the common reasons why your tire pressure light is on? Your tire pressure light may illuminate due to weather changes, air leaks, or issues with the TPMS itself.
There are several reasons why your tire pressure light might turn on in your 2019 Toyota Corolla. Understanding these reasons can help you address the issue quickly and effectively.
2.1. Temperature Fluctuations
Can temperature fluctuations affect tire pressure? Yes, temperature fluctuations can cause tire pressure to decrease, triggering the TPMS light.
As the temperature drops, the air inside your tires contracts, leading to lower pressure. For every 10-degree Fahrenheit decrease in temperature, your tire pressure can drop by about 1 PSI. This is a common reason for the tire pressure light to come on during the colder months. According to experts at Tire Rack, it’s essential to check your tire pressure regularly during seasonal changes to ensure it remains within the recommended range.
2.2. Air Leaks
What causes air leaks in tires? Air leaks can be caused by punctures, damaged valve stems, or corrosion on the wheel.
Even small punctures from nails, screws, or other road debris can cause your tires to lose air gradually. Damaged valve stems or corrosion on the wheel can also lead to slow leaks. It’s important to inspect your tires regularly for any signs of damage and address any leaks promptly. Miller Toyota’s service department can help you identify and repair any leaks to keep your tires properly inflated.
2.3. TPMS Sensor Issues
What are some TPMS sensor issues that can cause the light to come on? A blinking tire pressure light often indicates a problem with the TPMS sensors, such as a dead battery or malfunction.
The TPMS sensors inside your tires have a limited battery life, typically around 5-7 years. When the battery dies, the sensor will stop functioning properly, causing the tire pressure light to blink. A blinking light can also indicate a more serious issue with the TPMS, such as a faulty sensor or a problem with the system’s computer. If you see a blinking tire pressure light, it’s best to have your TPMS checked by a qualified technician at Miller Toyota.
2.4. Natural Air Loss
Do tires naturally lose air over time? Yes, tires naturally lose air over time due to permeation, even without punctures or leaks.
Even if your tires are in perfect condition, they will still lose some air over time due to permeation. This is a natural process where air molecules escape through the tire’s rubber. On average, tires lose about 1-2 PSI per month due to permeation. Regularly checking and inflating your tires can help compensate for this natural air loss.
3. Step-by-Step Guide: How to Reset Tire Pressure Light on Toyota Corolla 2019
What is the process for resetting the tire pressure light on a 2019 Toyota Corolla? Resetting the tire pressure light involves ensuring proper tire inflation, locating the reset button, and following the specific steps for your vehicle model.
If your tire pressure light remains on after you’ve inflated your tires to the recommended pressure, you may need to reset the TPMS manually. Here’s a step-by-step guide on how to reset the tire pressure light on your 2019 Toyota Corolla:
3.1. Ensure Proper Tire Inflation
Why is it important to ensure proper tire inflation before resetting the TPMS? Ensuring proper tire inflation before resetting the TPMS is crucial for accurate readings and optimal tire performance.
Before you reset the TPMS, make sure all your tires are inflated to the recommended pressure listed on the sticker on your driver’s side doorjamb. Use a reliable tire pressure gauge to check the pressure in each tire and adjust as needed. It’s best to check your tire pressure when the tires are cold, as driving can increase the temperature and pressure inside the tires.
3.2. Locate the TPMS Reset Button
Where is the TPMS reset button located on a 2019 Toyota Corolla? The TPMS reset button on a 2019 Toyota Corolla is typically located under the steering wheel, near the glove compartment, or in the center console.
The location of the TPMS reset button can vary slightly depending on the model and trim level of your Toyota Corolla. Consult your owner’s manual if you’re having trouble locating the reset button. In many 2019 Corollas, the reset button is found under the steering wheel, near the glove compartment, or in the center console.
3.3. Resetting the TPMS
What are the steps to reset the TPMS on a 2019 Toyota Corolla? The steps to reset the TPMS involve turning the ignition on, pressing and holding the reset button, and waiting for the tire pressure light to blink.
Here are the detailed steps to reset the TPMS on your 2019 Toyota Corolla:
- Turn the ignition on: Insert your key into the ignition and turn it to the “ON” position, but do not start the engine.
- Locate the TPMS reset button: Find the TPMS reset button as described above.
- Press and hold the reset button: Press and hold the TPMS reset button until the tire pressure light on your dashboard blinks three times. This may take several seconds.
- Release the reset button: Once the light blinks three times, release the reset button.
- Start the engine: Start your engine and drive for a few minutes to allow the TPMS to recalibrate. The tire pressure light should turn off after a short distance.
3.4. Alternative Reset Method (If Applicable)
Is there an alternative method to reset the TPMS on a 2019 Toyota Corolla? Some Toyota Corolla models may allow you to reset the TPMS through the vehicle’s infotainment system.
Some 2019 Toyota Corolla models may offer an alternative method to reset the TPMS through the vehicle’s infotainment system. Here’s how:
