A-Premium 433MHz TPMS Sensor Pre-programmed for Subaru — CR2050 Battery, Aluminum Valve

The A-Premium 433MHz pre-programmed TPMS sensor replaces factory tire pressure sensors for compatible Subaru models, delivering certified 433 MHz wireless monitoring with durable aluminum valves and long-life batteries.

Designed as a direct-fit replacement for many Subaru vehicles, this A-Premium TPMS sensor comes pre-programmed and factory-tested to meet SAE-style performance checks while carrying FCC, IC and CE certifications. The sensor uses a high-precision NXP chip and a CR2050 battery to transmit tire pressure and temperature data within a 0–900 kPa range, and is built to tolerate extreme temperatures from -40°C to 120°C. Although programmed at the factory for the listed part numbers, a relearn or pairing procedure is required after installation to sync the sensor with your vehicle's TPMS receiver.

Which Subaru models and part numbers does this sensor fit?

This sensor fits a range of Subaru models from recent years, covering both front and rear wheel positions. Match your vehicle year and model to the compatible list and verify against OE reference numbers before purchase.

• Compatible models: Ascent (2019–2024), Crosstrek (2018–2024), Forester (2019–2024), Impreza (2017–2024), Legacy (2018–2024), Outback (2018–2024), WRX (2024).
• Reference numbers supported: 28103FL00A, 28103FL00B, 28103FL001, 28103FL013.
• Suitable for both front and rear positions; confirm left/right fitment with your vehicle manual.

How reliable and durable is the A-Premium TPMS sensor?

Built with a polyamide plastic housing and an upgraded aluminum valve, the sensor is engineered for road use and harsh climates. The NXP chip and CR2050 battery combination, plus in-house SAE J2657-style testing, provide consistent signal transmission and extended service life.

• Operating temperature range: -40°C to 120°C for extreme-weather reliability.
• Materials: polyamide body and aluminum alloy valve for corrosion resistance.
• Tested per SAE-style procedures; includes FCC, IC and CE certifications for compliance.

Does "pre-programmed" mean I can install and drive immediately?

Pre-programmed indicates the sensor is set to the correct frequency and ID before shipping, but most vehicles still require a relearn or initialization step. The sensor will physically fit without coding tools on compatible wheels, yet you must follow your vehicle's relearn procedure so the car recognizes the new sensor IDs.

• No special coding hardware needed for fitment; sensor ships programmed.
• Refer to your Subaru owner's manual for the relearn/pairing process specific to year and model.
• Dealership or aftermarket TPMS tool can perform relearn if manual procedure is unavailable.

What performance specifications should I expect from this TPMS sensor?

The sensor communicates at 433 MHz and reports pressure and temperature within automotive ranges. It supports monitoring across typical driving conditions and integrates with vehicle TPMS systems once relearned.

• Frequency: 433 MHz for wireless transmission compatible with listed Subaru systems.
• Pressure monitoring range: 0–900 kPa (suitable for passenger vehicle tires).
• Battery: CR2050 long-life cell included; designed for extended service life.

Who this is for: Drivers who own compatible Subaru models and need an OE-style replacement sensor that balances certified performance with robust hardware. Choose this A-Premium sensor if you want a pre-programmed, tested unit with upgraded aluminum valves and proven components, and be prepared to perform the vehicle-specific TPMS relearn or have a technician complete it. A two-year product guarantee is included for added confidence when replacing worn or failed OE sensors.
