• Quality Iteration. Compared to other metal materials, A-Premium's Tire Pressure Monitoring System Sensor is made of upgraded aluminum alloy valves, which ensure a stable use experience due to its strong corrosion resistance and heat conductivity.
• Extend Tire Life. Relying on the new generation of NTM88 chip technology, it can monitor the tire pressure in real time, know the tire status, and provide sensitive feedback and timely response for safe driving, which is not possible with other chips.
• Powerful Battery Life. The Maxel or Panasonic CR2050 battery used in the A-Premium's Tire Pressure Monitoring System Sensor can last at least 5 years with its high and low temperature resistance and low energy consumption, and outperforms other similar products in terms of battery life.
• Compatible with a Wide Range of Usage Scenarios. A-Premium's Tire Pressure Monitoring System Sensor is not only compatible with temperatures ranging from -40 degrees to 120 degrees, but also has excellent sealing properties, making it the strongest waterproof and dustproof product of its kind.
• Multiple Test Endorsements. A-Premium is salt spray and pressure tested to meet the stringent SAE J2657 standards, minimizing the frequency of follow-up maintenance in its class.

How the Subaru Forester TPMS monitors tire pressure

The Subaru Forester uses a direct tire pressure monitoring system to monitor tire pressure in all four tires. Each TPMS sensor is installed at the valve and measures air pressure inside the tire. Pressure data is transmitted via radio frequency to the vehicle system, which continuously checks for abnormal pressure readings. When tire pressure drops below the recommended level, the system triggers a warning light on the dashboard to alert the driver.

Recommended tire pressure and proper inflation

Proper tire pressure for a Subaru Forester is specified by the manufacturer and can be found on the driver-side door jamb or in the Subaru owner’s manual. Tire pressure should be checked when tires are cold to ensure accurate readings. Maintaining proper inflation helps prevent uneven wear, supports stable handling, and improves overall safety and performance. Incorrect pressure may also affect fuel efficiency and tire lifespan.

What triggers the TPMS warning light on a Subaru Forester

The TPMS warning light is commonly triggered by low tire pressure caused by air loss or temperature changes. It may also appear after installing new tires or wheels if the TPMS system has not been reset or sensors are not correctly registered. In some cases, a weak sensor battery or sensor malfunction can cause the warning light to remain on even when tire pressure is normal.

Resetting and programming Subaru Forester TPMS sensors

After a TPMS sensor is replaced or wheels are changed, the Subaru Forester TPMS system may require a reset or programming process. This allows the vehicle to recognize each sensor and restore normal monitoring. Programming is typically performed using a TPMS tool and may be handled by a tire shop or certified technicians. Once properly programmed and tire pressure is corrected, the TPMS system will operate normally.
