How does Subaru monitor tire pressure?

Subaru Tire Pressure Monitoring System (TPMS)
Subaru vehicles are equipped with a Tire Pressure Monitoring System (TPMS) to monitor tire pressure and alert drivers if the pressure is too low or too high. The TPMS helps ensure that tires are properly inflated, which is important for various reasons, including optimal handling, fuel efficiency, and tire life.
How does Subaru monitor tire pressure?
Subaru monitors tire pressure through sensors installed in each wheel. These sensors measure the tire pressure and transmit the information to the vehicle’s Electronic Control Unit (ECU). If the sensors detect that the tire pressure is outside the recommended range, the TPMS alert will be displayed on the dashboard, indicating which tire(s) need attention.
How to check and adjust tire pressure in a Subaru?
To check and adjust tire pressure in a Subaru, you can follow these steps:
1. Check the recommended tire pressure: The recommended tire pressure for your specific Subaru model can usually be found on a sticker located in the driver’s door jam area.
2. Use a pressure gauge: If you have a pressure gauge, you can use it to check the current tire pressure. It is best to check the tire pressure in the morning before driving, as driving can heat up the tires and give an inaccurate reading.
3. Adjust the tire pressure: If the tire pressure is too low or too high, you can add or release air accordingly to reach the recommended pressure. It is important to maintain the correct tire pressure for optimal performance and safety.
Changing the TPMS settings in a Subaru
If you need to change the Tire Pressure Monitoring System (TPMS) settings in your Subaru, such as switching the measurement from kPa to PSI, you can refer to the owner’s manual or watch instructional videos specific to your Subaru model and year. These resources provide step-by-step instructions on how to change the TPMS settings.
Conclusion
Subaru monitors tire pressure using sensors installed in each wheel, which transmit the information to the vehicle’s ECU. The TPMS alerts the driver if the tire pressure is outside the recommended range. To check and adjust tire pressure in a Subaru, you can refer to the recommended tire pressure sticker and use a pressure gauge. If you need to change the TPMS settings, you can consult the owner’s manual or watch instructional videos specific to your Subaru model and year .

What is the life expectancy of a Subaru TPMS sensor?

TPMS Life Expectancy
The estimated life expectancy of an OE TPMS sensor is 5 to 12 years, with the average lifespan being 7 years. TPMS life expectancy is directly related to the number of radio frequency transmissions the sensors make.

Where is the TPMS button on Subaru?

Unfortunately, Subaru doesn’t install a TPMS reset switch on cars sold in the U.S. If the warning light remains illuminated even after you’ve confirmed that your tires are inflated to the correct pressure, you’ll need to visit a tire shop or a dealership to have the system reset.

How do TPMS sensors know which wheel?

The sensors inside each tire, have serial numbers so the car’s TPMS system can identify the location of each individual sensor.

Do Subarus have tire pressure sensors?

Video Explaining Your Subaru Tire Pressure Monitoring System (TPMS) In this video you’ll learn about your Tire Pressure Monitoring System operation and dashboard display indicators. There could be several reasons for loss in tire pressure.

What brand of TPMS does Subaru use?

Schrader Electronics
The manufacturers of the Subaru TPMS are Schrader Electronics. The tables below show which models they are fitted to. Grey indicates either no TPMS, it was indirect TPMS, or the model was discontinued.

How does Subaru tire pressure monitoring system work?

A transmitter with a tire pressure sensor is located inside the each tire’s air valve stem. It is designed to detect low pressure only (not high or over-inflated). The sensor contains a battery. Battery life is 10 years or 100,000 miles.

Does Subaru use direct or indirect TPMS?

Your Subaru uses the direct type, which uses a wheel-mounted, battery-powered sensor. More than likely, one or more of the tire pressure sensors is failing. These battery-powered sensors have an expected life of seven to 10 years.

How do you check tire pressure on a Subaru dashboard?

When we get to the tire pressure monitoring. Page we’ll notice a picture of our vehicle. And four numbers to the left and right of that picture the numbers indicate our tire.

How does my car monitor tire pressure?

Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. When air pressure drops 25% below the manufacturer’s recommended level, the sensor transmits that information to your car’s computer system and triggers your dashboard indicator light.

How does tire pressure sensor communicate with car?

The sensor transmits that information via low-frequency radio to the vehicle’s onboard computer and, if the car has one, to a corresponding display in the instrument cluster. It reads out in pounds per square inch (psi), and it illuminates an amber warning light to alert you if one or more tires are low on air.
