TPMS Sensor 4Pack 315MHz for Subaru - Preprogrammed Replacement

In this review the tester focused on whether these preprogrammed TPMS sensors make replacing failed units on Subaru models easier and more reliable. The bottom line is that the 4Pack of 315MHz sensors is a pragmatic choice for owners of compatible Subaru vehicles who want a neardropin replacement that only needs activation with a TPMS scan tool. Installation is straightforward for anyone comfortable using a diagnostic trigger tool, and the product's emphasis on a longlife CR2032 battery and preprogramming reduces the usual setup headaches.

Key Features

• Preprogrammed sensor: Each sensor arrives already programmed for specific Subaru make/model/years so users only need to wake them with a TPMS scan tool to display sensor data.
• 315MHz frequency: Uses the OEM compatible 315MHz signal to communicate reliably with the vehicle TPMS receiver on supported Subaru models.
• Durable battery: Equipped with a CR2032 battery designed to last 5-8 years under normal conditions, reducing the need for frequent replacements.
• Wide temperature tolerance: Electronics rated to withstand very low and high temperatures so the sensor remains functional across seasonal extremes.
• OE part replacements: Directly replaces OE part numbers 28103AG00A, 28103AG01C, 28103AG01B and 28103AJ00A for easier cross reference during installation.

Who It's For

This pack is best for Subaru owners who need a reliable, cost effective replacement for failed TPMS sensors on compatible models such as Forester, Impreza, WRX, Outback, Legacy, Tribeca and Crosstrek. It suits DIY mechanics and independent shops that already own or can borrow a TPMS scan tool to activate and register the sensors.

It is less suitable for drivers who expect fully automatic cloning without any scan tool interaction or for vehicles outside the listed Subaru model years. Buyers without access to a TPMS wake/scan device will need to budget for that additional tool or service charge.

Pros & Cons

Pros

• Preprogrammed units reduce setup steps and are ready to be activated with a TPMS scan tool.
• Compatibility with common Subaru models simplifies selection and replacement planning.
• CR2032 battery and robust chip design promise multiyear service life and temperature resilience.

Cons

• Requires a TPMS scan tool to wake and register the sensors, so some users may need extra equipment or professional help.
• Customers report mixed experiences with programming accuracy on a few model years, so doublechecking fitment before purchase is wise.
