What TPMS sensors does Subaru use?
Subaru vehicles are equipped with Tire Pressure Monitoring System (TPMS) sensors to help drivers maintain proper tire inflation. These sensors monitor the air pressure in each tire and alert the driver if any tire's pressure falls below a certain threshold. Subaru's TPMS sensors use a specific technology to provide this important safety feature.
What is TPMS?
TPMS is a safety system that monitors the air pressure in a vehicle's tires. It alerts the driver when one or more tires are significantly underinflated, which can improve fuel efficiency, handling, and tire life. TPMS is required by law in many countries, including the United States, to help prevent tire-related accidents.
Subaru's TPMS Sensor Technology
Subaru vehicles use direct TPMS sensors, which are installed in each wheel and directly measure the air pressure in that tire. These sensors transmit the pressure data wirelessly to the vehicle's computer, which then displays the information on the dashboard.
The key features of Subaru's TPMS sensors include:
- Direct measurement of tire pressure in each wheel
- Wireless transmission of data to the vehicle's computer
- Battery-powered sensors that can last the life of the vehicle
- Ability to detect slow leaks and rapid pressure drops
- Integration with the vehicle's warning lights and dashboard display
Subaru's use of direct TPMS sensors provides more accurate and reliable tire pressure monitoring compared to indirect systems that estimate pressure based on wheel speed sensors. This helps Subaru owners maintain proper tire inflation for improved safety, fuel efficiency, and tire longevity.
How to reprogram TPMS sensors on a Subaru?
Hold the TPMS reset button until the tire pressure light blinks three times, then start the car and wait 20 minutes for recalibration. The reset button is usually beneath the steering wheel, or consult your user's manual.
What frequency is Subaru TPMS?
Type of TPMS frequency:
315 MHz, years 2015-2017. 433 MHz, years 2018-2020.
How do I know which TPMS sensor I have?
The TPMS Sensor ID can be located in various locations on the TPMS sensor and can be either numeric or alphanumeric. TPMS sensors using a numeric ID will consist of 0-9. TPMS sensors using a alphanumeric ID will consist of 0-9 and A-F. These 16 characters provide more than 2 trillion sensor ID combinations.
How to figure out which tire pressure sensor is bad?
Measure the air pressure of each tire and record them. Then, compare the data with the one displayed in your car display panel. If the reading in one tire is different from the one displayed, it might mean that there's a problem with the TPMS sensor in that tire.
Are TPMS sensors brand specific?
Aftermarket TPMS sensors are produced by third-party manufacturers, such as Autel or Xtool. They are designed to be compatible with a range of vehicle makes and models, but they are not specifically made for any one vehicle.
What kind of TPMS sensor does Subaru use?
A TPMS from Schrader Electronics is fitted as part of the valve assembly in all Subaru cars according to the table shown below.
Do TPMS sensors have to match?
Every replacement TPMS sensor must be “relearned” to the vehicle following the prescribed OE relearn procedure, regardless of whether it is an OE or aftermarket sensor.
What is the best brand of TPMS sensors?
Well-regarded brands for TPMS sensors include Schrader, Continental, ACDelco, and Bosch. These brands are known for their reliability and quality.
Are OEM TPMS sensors better than aftermarket?
Contact OE TPMS distributors like TPMS Direct. OE TPMS Sensors last longer, have a 1 in 1 million failure rate, come with a manufacturer warranty, and are much better understood by auto shops around the country.
How long do Subaru TPMS sensors last?
Most TPMS sensors run on batteries that are built into the sensor and these batteries are not replaceable. The life expectancy of the lithium ion batteries in a TPMS sensor is anywhere from 5-10 years.
