What is the Tire PRessure Monitoring System?
A tire pressure monitoring system is a safety feature that alerts drivers to low tire pressure. Low tire pressure can cause poor fuel economy, uneven tire wear, and even tire failure. The TPMS in the 2017 Toyota Highlander is designed to monitor the tire pressure of all four tires and alert the driver if there is a problem.
How Does the TPMS Work in the 2017 Toyota Highlander?
The TPMS in the 2017 Toyota Highlander consists of several components, including the tire pressure sensors, the TPMS receiver, and the vehicle’s computer. The system works by continuously monitoring the tire pressure and transmitting the data to the vehicle’s computer.
The tire pressure sensors are located inside each tire and measure the air pressure in each tire. The sensors send a signal to the TPMS receiver, which is located in the vehicle’s cabin. The receiver then sends the data to the vehicle’s computer, which analyzes the information and determines if any tire is underinflated.
If the TPMS detects low tire pressure in any of the tires, it will alert the driver with a warning light on the dashboard. The warning light looks like a horseshoe with an exclamation point in the center, within the RPM tachometer. The driver should check the tire pressure and inflate the tire to the recommended pressure as soon as possible.
How to Reset Toyota Highlander TPMS
Be sure the tires are at the correct pressure.
Have the car ON or Running.
Hold down the TPMS button. (found under the steering wheel, behind the gas door button)
The TPMS warning light will flash about 3 times.
Once the TPMS light stops flashing, release the TPMS button.
When to Perform TPMS Reset Procedure:
After rotating tires: When you rotate your tires, the TPMS sensors may need to be relearned to recognize the new tire positions.
After changing a tire: If you replace a tire, the TPMS system will need to be reset to recognize the new tire and sensor.
After changing wheels or tires: If you install aftermarket wheels or tires that do not have compatible TPMS sensors, the system will need to be reset or new sensors will need to be installed. (or you can transfer the sensors from old wheels to new wheels without having to reprogram new sensors)
After adjusting tire pressure: If you adjust the tire pressure, the TPMS system may need to be reset to recognize the new pressure values.
After performing maintenance on the TPMS system: If you replace a sensor or perform any maintenance on the TPMS system, a reset may be necessary to ensure proper functioning.
If the TPMS warning light comes on: If the TPMS warning light comes on, it may indicate a problem with the system or a low tire pressure condition. In this case, a reset may be necessary to clear the warning and ensure proper functioning.
As part of regular maintenance: It’s a good practice to perform a TPMS reset as part of your regular vehicle maintenance routine, such as during a tune-up or oil change. This can help ensure that the system is functioning properly and detecting any issues early.
Causes For TPMS Light To Turn On:
Low tire pressure in one or more tires
High tire pressure in one or more tires
A punctured or damaged tire
A malfunctioning tire pressure sensor
A faulty TPMS receiver or computer
A battery failure in the tire pressure sensor
Aftermarket wheels or tires that do not have compatible sensors
The TPMS system needing to be reset after rotating the tires or changing a tire
These are some of the most common reasons why the TPMS warning light may turn on in the 2017 Toyota Highlander. If you notice the warning light, it’s important to check the tire pressure and address any issues as soon as possible to ensure your safety and the proper functioning of your vehicle.
Benefits of TPMS
Improved safety: TPMS helps to ensure that your tires are properly inflated, reducing the risk of accidents caused by underinflated or overinflated tires.
Longer tire life: Properly inflated tires wear more evenly and last longer, reducing the need for replacements.
Increased fuel efficiency: Properly inflated tires can improve fuel efficiency, saving you money on gas and reducing your carbon footprint.
Better handling and performance: Properly inflated tires provide better handling, stability, and performance, especially in challenging driving conditions.
Reduced maintenance costs: Regular monitoring of tire pressure can help detect issues early, reducing the need for costly repairs or replacements.
Compliance with regulations: Many countries and regions have regulations requiring vehicles to have TPMS installed, so having it can ensure compliance and avoid fines or penalties.
Convenience: With TPMS, you don’t have to manually check tire pressure as often, saving you time and effort.
How to Check Tire Pressure
How to Check the Tire Pressure in the 2017 Toyota Highlander?
To check the tire pressure in the 2017 Toyota Highlander, you need a tire pressure gauge. You can find the recommended tire pressure for your vehicle in the owner’s manual or on the driver’s side door jamb.
To check the tire pressure, remove the valve cap from the tire and press the tire pressure gauge onto the valve stem. The gauge will measure the air pressure in the tire and display the reading on the gauge. Compare the reading to the recommended tire pressure and add or release air as needed.
Tire Maintenance
To ensure proper tire pressure and maintain optimal vehicle performance and safety, it’s important to adjust tire pressure when the tires are cold. Temperature changes can affect tire pressure, causing cold tires to contract and have lower pressure, while hot tires expand and have higher pressure. The manufacturer’s recommended tire pressure is based on cold tire measurements to ensure accuracy. Over-inflating tires can cause blowouts or loss of tire tread, which can be dangerous. Checking tire pressure when the tires are cold, before driving or after the vehicle has been parked for a while, ensures that accurate pressure levels are maintained and potential issues are avoided.
Conclusion
In conclusion, the tire pressure monitoring system in the 2017 Toyota Highlander is an important safety feature that alerts drivers to low tire pressure. The system uses tire pressure sensors to measure the air pressure in each tire and sends the data to the vehicle’s computer. If the TPMS detects low tire pressure in any of the tires, it will alert the driver with a warning light on the dashboard. By understanding how the TPMS works and checking the tire pressure regularly, you can help ensure that your vehicle is safe and performing at its best.
