How To Fix Subaru Tire Pressure Sensor Problem?

The tire pressure monitoring system (TPMS) assists Subaru drivers in keeping their tires correctly inflated for maximum fuel efficiency, handling, and tire wear. However, the sensors that monitor each tire might occasionally malfunction, causing problems. How to fix Subaru tire pressure sensor problem?

Check that all tires are inflated to the correct pressure per Subaru’s specifications. Next, examine the sensors for obvious damage or corrosion. Reset the tire pressure monitoring system by pressing the reset button, which is normally placed at the steering wheel or in the glove compartment. If the problem continues, it may necessitate professional diagnosis and repair. You should resolve tire pressure sensor problems as soon as possible to guarantee safe driving, optimal fuel efficiency, and tire longevity.

What Are Subaru Tire Pressure Sensor Problems?

Problems with the Subaru tire pressure sensor might appear in a number of ways, such as:

Sensor Malfunction

It is possible for the tire pressure sensor to malfunction, resulting in erroneous readings or no data transmission at all. The tire pressure warning light on the dashboard may illuminate as a result, signaling a problem with one or more tires.


Corrosion on the sensor or any of its components could impair the sensor’s ability to function. It thus either produces erroneous results or malfunctions totally. This is particularly common in areas exposed to salt on the roadways or that receive harsh weather.

Battery Failure

Internal batteries in some tire pressure sensors may eventually run out of power. It results in occasional communication problems or sensor failure.

Physical Damage

Damage to the sensor from road debris, curbs, or accidents can impair its ability to function properly. It results in inaccurate readings or complete failure.

System Calibration Issues

If the TPMS is not properly calibrated or there is a software failure, it may produce incorrect tire pressure warnings or inconsistent readings.


Electronic interference from surrounding sources can disrupt the connection between sensors and the vehicle’s TPMS receiver. It can result in erroneous readings or problems.

How To Fix Subaru Tire Pressure Sensor Problem?

To resolve a Subaru tire pressure sensor issue, follow these steps:

Check Tire Pressure

Begin by manually checking the pressure in all tires with a dependable tire pressure gauge. Inflate any underinflated tires to the required pressure found in your Subaru owner’s manual or on the driver’s side door jamb.

Inspect Sensors

Examine each tire pressure sensor for physical damage, corrosion, or obvious evidence of wear. Make that the sensors are securely placed and there are no loose or broken components.

Reset TPMS

Attempt to reset the tire pressure monitoring system (TPMS) by pressing the reset button located inside the car, usually at the steering wheel or in the glove box. You can find specific instructions for doing a TPMS reset in your Subaru owner’s manual.

Replace Faulty Sensors

If the tire pressure sensor is damaged, malfunctioning, or cannot be reset, it may have to be replaced. Purchase a compatible replacement sensor and install it per the manufacturer’s directions. Some sensors may require programming or calibration following installation.

Professional Diagnosis

If the tire pressure sensor problem persists after completing the techniques outlined above, expert diagnosis and repair may be necessary. Take your Subaru to a certified mechanic or dealer who has experience diagnosing and repairing TPMS problems. They can utilize sophisticated diagnostic tools to determine the underlying source of the problem and offer an appropriate solution.

System Calibration

After replacing a tire pressure sensor or conducting any repairs, ensure that the TPMS is properly calibrated to monitor tire pressures. Follow any calibration procedures described in your Subaru owner’s manual or as directed by a mechanic.

Applying these instructions will allow you to successfully handle and resolve tire pressure sensor issues in your Subaru. This contributes to the safe and dependable running of the road.

How Do You Reset The TPMS Sensor On A Subaru?

Ensure Proper Tire Pressure

Before you reset the TPMS sensor, make sure all of your tires are properly filled to the specified levels. The owner’s manual or a placard on the driver’s side door jamb contain this information.

Locate Reset Button

Usually found inside the glove compartment or under the steering wheel, the TPMS reset button is compatible with most Subaru vehicles. To find out the precise location in your car, go to the owner’s manual.

Turn Ignition On

Once the engine is off and the ignition is in the “ON” position, find the TPMS reset button.

Press and Hold Reset Button

Once the TPMS warning light begins to blink on the dashboard, press and hold the TPMS reset button for a few seconds. The system is restarting as a result of the flashing.

Release Button

Press and hold the reset button until the TPMS warning light blinks three times.

Wait for Confirmation

As soon as the TPMS warning light goes out, you should reset the system successfully. This can take a few minutes to complete.

Test System

To make sure the TPMS is operating properly, turn on the car and drive a short distance once the warning light has gone out. Make sure the tire pressure warning light stays off by checking.
