CARPMS TPMS Sensor for Subaru 433MHz Set of 4 — IP67 Waterproof, 5+ Year Battery

CARPMS TPMS Sensor for Subaru is a set of four 433MHz tire-pressure monitoring sensors that deliver accurate, long‑lasting pressure and temperature readings to help maintain safe tire PSI.

These CARPMS sensors are built to replace factory units on many Subaru models while offering durable weatherproof housings, extended battery life, and FCC‑grade signal stability. They come pre-programmed at the factory to the correct 433MHz frequency but require a vehicle re-learn or reset so your car’s ECU recognizes them. Designed for everyday commuting and long-distance travel, they balance precise telemetry with rugged construction for reliable on-road performance.

Which Subaru models are compatible with these TPMS sensors?

The CARPMS 433MHz sensors fit a broad range of Subaru vehicles produced in recent years. Compatibility covers popular models including Crosstrek, Forester, Outback, Ascent, Legacy, and Impreza generations listed by year ranges. Always check your OEM part number and model year to confirm fitment before purchase.

• Compatible models: Crosstrek 2018–2026, Forester 2019–2026, Outback 2018–2026
• Also fits Ascent 2019–2025, Legacy 2018–2025, Impreza 2017–2024, WRX 2022–2025
• Replacement OEM part numbers: 28103FL00A, 28103FL013, 28103FL00C, 28103FL00E, 28103FL010, 28103FL00B

How reliable and durable are these sensors in harsh conditions?

CARPMS sensors are engineered to withstand road and weather stresses with IP67-rated housings and a wide operating temperature range. They use CR2050 batteries rated for more than five years under typical driving conditions and a premium chipset for consistent signal transmission. The ruggedized casing resists water, dust, vibration, and road salt for long-term stability.

• IP67 waterproof and dustproof construction for rain, car washes, and snow
• Operational range: -40°F to 257°F to handle extreme climates
• Over 5 years of battery life with high-capacity CR2050 cells

What data and alerts will I see once installed?

After re-learning, the vehicle will receive real-time tire pressure and temperature information through the car’s TPMS dashboard system. The sensors trigger alerts for low pressure, high temperature, and slow leaks, helping you address issues before they worsen. This telemetry assists with fuel economy and tire longevity by keeping PSI within recommended ranges.

• Instant dashboard alerts for low pressure, high temperature, and leaks
• Continuous pressure and temperature monitoring for each tire
• Designed to help maintain optimal PSI for better fuel economy and tire wear

Do these sensors come ready to use, or is programming required?

CARPMS sensors arrive pre-programmed to the correct frequency, but they are not automatically recognized by every vehicle without a re-learn or reset. Some cars will accept the sensor after a simple re-learn sequence; others require a diagnostic scanner or activation tool to complete pairing. Follow your vehicle’s manual or seek professional installation if you’re unsure.

• Pre-programmed at the factory for 433MHz operation
• Re-learn/reset required; procedures vary by vehicle model
• Professional scanner or technician may be needed for some Subaru models

Who is this for: These CARPMS TPMS sensors are aimed at Subaru owners who need accurate OEM-style replacements that last. They suit drivers who value long battery life, rugged weather resistance, and reliable alerts for pressure and temperature. Ideal for owners replacing worn sensors, performing a tire service, or upgrading to a durable aftermarket TPMS solution while keeping factory part-number compatibility.
