Do Subaru TPMS need to be programmed?
Tire Pressure Monitoring Systems (TPMS) are an essential safety feature in modern vehicles, including Subarus. They help ensure your tires are properly inflated, improving fuel efficiency, tire longevity, and overall safety. If you're a Subaru owner, you might wonder whether the TPMS sensors in your vehicle need to be programmed. Let's dive into the details to clarify this important question.
What Is TPMS and How Does It Work?
TPMS is a system designed to monitor the air pressure inside your tires and alert you if the pressure drops below a safe level. Subaru vehicles typically use direct TPMS, which relies on sensors installed in each tire to measure pressure and transmit the data to your car's onboard computer. This ensures you receive real-time alerts if any tire is underinflated.
Do Subaru TPMS Sensors Need Programming?
Yes, Subaru TPMS sensors often need to be programmed or relearned to communicate with your vehicle's onboard computer. When you replace or install new TPMS sensors, they must be synchronized with your car's system to function correctly. This process ensures the sensors transmit accurate tire pressure data to your dashboard.
When Is TPMS Programming Necessary?
There are several scenarios where TPMS programming or relearning is required for Subaru vehicles:
- Replacing TPMS Sensors: If you install new sensors, they need to be programmed to match your vehicle's system.
- Rotating Tires: Some Subaru models require a relearn procedure after tire rotation to ensure the system recognizes the new positions of the sensors.
- Installing Winter Tires: If you use a separate set of wheels for winter tires, the TPMS sensors in those wheels may need to be programmed.
- Battery Replacement in Sensors: If the sensor batteries are replaced, the system may need to be recalibrated.
How Is TPMS Programming Done?
Programming or relearning Subaru TPMS sensors typically requires specialized tools. Here's an overview of the process:
- Using a TPMS Tool: A TPMS programming tool is used to activate and program the sensors. This tool communicates with the sensors and your vehicle's computer.
- Following Manufacturer Instructions: Subaru provides specific instructions for relearning TPMS sensors, which vary by model and year.
- Professional Assistance: Many Subaru owners rely on professional auto repair shops to handle TPMS programming, as it requires expertise and the right equipment.
Why Is Proper Programming Important?
Properly programmed TPMS sensors are crucial for accurate tire pressure monitoring. If the sensors are not programmed correctly, you may receive false alerts or fail to be notified of low tire pressure, which can compromise your safety on the road. Additionally, an improperly functioning TPMS system may cause your vehicle to fail state inspections in areas where TPMS functionality is required by law.
Conclusion
In summary, Subaru TPMS sensors do need to be programmed or relearned in specific situations, such as sensor replacement or tire rotation. Ensuring your TPMS system is functioning correctly is vital for your safety and the longevity of your tires. If you're unsure about programming your Subaru's TPMS sensors, don't hesitate to visit a trusted auto repair shop like Kevin's Autos, where experienced professionals can assist you with all your TPMS needs.
Frequently Asked Questions
What is the TPMS failure on a Subaru?
TPMS replacement is called for when the TPMS fails due to mechanical or electrical failure, broken accelerometer, low TPMS battery power or blocked pressure port. One of the most common causes of failure is inappropriate handling during wheel or tire removal or servicing.
Does a new TPMS sensor need to be programmed?
These sensors must be programmed with the proper protocol/application information for the vehicle before they can be installed in the tire, and then must be relearned to the vehicle. Unfortunately, some shops overlook the necessary relearn step mistakenly believing the sensor programming did the trick.
How do you reprogram a 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.
What type of TPMS does Subaru use?
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 long does it take for a new TPMS sensor to reset?
about 20 minutes
Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh.
What is the TPMS problem 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.
Can you program a TPMS sensor after it's installed?
After selecting the specific vehicle being serviced, Schrader recommends programming the sensor prior to installation to the wheel. However, EZ-sensor® can be programmed through the sidewall of the tire after installation.
Can I replace my TPMS sensors myself?
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.
Can I reset my TPMS myself?
Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait about 20 minutes for the sensor to refresh. You will find the tire pressure monitor reset button under the steering wheel. Refer to your vehicle's owner's manual if you can't find it.
How do I know if TPMS is compatible?
There are many OEM tpms part numbers that are referenced and cross referenced. TPMS sensor part numbers can change by vehicle production year and month so we always suggest using your vehicles VIN number to check for exact fitment from the vehicle manufacturer.
