What does TPMS mean on a Subaru?
The TPMS light indicates that one or more of your tires on your Subaru is low on pressure. This might be a result of a puncture or a leak, or it could just the result of a big swing in the outside temperature. Here’s Why You Shouldn’t Ignore the TPMS Light: Tires that are low on pressure cannot make proper contact with the road, causing significant and uneven wear. Uneven tread wear reduces the tire’s life dramatically, which leads to costly and premature replacement.Overinflated and underinflated tires are the most common reason why your TPMS light would turn on or start flashing. Your TPMS is designed to detect tire pressure that is too high or too low.The tire sensor sends a radio frequency (RF) signal of 315 or 433 MHz to the ECU. The ECU checks the pressure, and then displays the TPMS symbol or a position-specific display. If the dashboard warning light flashes for 1-2 minutes, it is important to diagnose and reset the TPMS system.Tire Pressure Light On But Tires Are Fine Sometimes you check your tires, and they seem perfectly inflated—but that light is still glowing. Here’s why: Possible TPMS sensor malfunction: Sensors can fail over time, especially in older vehicles. A malfunctioning sensor might falsely trigger the warning light.

How do you clear the TPMS light on a Subaru?
Drive your vehicle at 20–25 mph for at least 10 minutes. Turn off the engine, then restart your car to see if the light disappears. If the light stays on, check for a reset button under the dashboard near the steering wheel. Press and hold the reset button until the TPMS light blinks, then release. Press and hold the TPMS reset button until the tire pressure light blinks three times. Release the button and start the car. The light should go off within 20 minutes.Replacing a tire pressure sensor (TPMS sensor) is a task that can be handled by most do-it-yourself enthusiasts with the right tools and safety precautions.So, you don’t have to worry about making alterations that can interfere with the safety and performance of your vehicle. In summary, you can disable your tire sensors or TPMS.You should always reset your TPMS after changing or rotating tires, or installing new sensors. Some sensor manufacturers recommend resetting it even after adding air to your tires.
How to reset TPMS on a Subaru?
Key Position Reset: Turn the key to the “On” position without starting the engine. 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. Hold the TPMS reset button until the light blinks three times, then start the car and wait 20 minutes. The button is usually under the steering wheel—check your owner’s manual. Pressure Variation Reset: Inflate all tires 3 PSI above the recommended level, then deflate them completely (including the spare, if equipped).The TPMS System Needs Time to Recalibrate Many vehicles automatically reset the TPMS light after driving at speeds above 50 mph (80 km/h) for about 10–15 minutes. If the light remains on after driving, try turning off the engine, waiting a few minutes, and restarting the vehicle.If you have recently filled up your tires and the TPMS light remains illuminated, there are a few possible reasons: Sensor malfunction: One or more sensors in your TPMS system may be faulty, requiring professional inspection and repair.Drive at 50 mph or higher for 10 minutes: This can trigger a sensor reset when you turn off and restart the car. Utilize the TPMS reset button: First, ensure the vehicle is off, then turn the key to the “On” position without starting the car.
How long do Subaru TPMS last?
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. Normally, TPMS sensors are designed to last for 5 to 10 years. However, it’s important to note that their batteries are non-replaceable. So, when a sensor’s battery reaches the end of its life, the entire unit must be replaced.Replacing TPMS sensors is an important maintenance task that ensures your vehicle remains safe and efficient on the road. While professional replacement is always an option, doing it yourself can save you money and give you a sense of accomplishment.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.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.
What brand TPMS does Subaru use?
The manufacturers of the Subaru TPMS are Schrader Electronics. If you’re comfortable working on your vehicle, you can replace TPMS sensors yourself.While it’s technically possible to drive a car with a bad TPMS sensor valve, it’s not advisable for several reasons. Firstly, as outlined above, doing so compromises your safety and that of other road users. Secondly, it can result in increased running costs due to reduced fuel efficiency and accelerated tyre wear.TPMS failure can stem from various sources, including low battery voltage, damage from road debris, exposure to extreme temperatures, corrosion, sensor age, and faulty wiring. The TPMS sensor relies on battery power to function correctly; hence, low battery voltage can impair its operation.The cost of TPMS sensor batteries typically ranges from $20 to $200. Similarly, aftermarket TPMS sensors can cost anywhere from $10 to $380, which means you can already score a good-quality one for around $60.
How much does it cost to replace TPMS on a Subaru?
