Denso 550-2701 Tire Pressure Monitoring System Sensor

Denso OE Manufactured TPMS Sensor

Denso TPMS Sensor 550-2701 is a direct tire pressure monitoring system sensor built for vehicles that use a clamp-in, real-time pressure signal setup. It is designed for Subaru applications that require OE-style TPMS performance, including Subaru Tribeca, Subaru B9 Tribeca, Subaru Legacy, and Subaru Outback fitments.

As an OE Manufactured part, this sensor is built to preserve factory TPMS functions while supporting the vehicle’s original monitoring strategy. The Denso 550-2701 is a practical replacement for drivers addressing TPMS warning lights on 315 MHz Subaru systems.

Key Features

• Direct TPMS sensor with electric power source
• Real-time pressure signal transmission
• Clamp-in mounting method for OE-style wheel installation
• Mounting hardware included
• Gasket or seal included
• Supports factory TPMS system functions, including fill assist and auto locate
• Preserves diagnostic trouble codes for service diagnostics

OE Manufactured Design

Denso’s OE Manufactured line focuses on replacement parts built to match original vehicle system requirements. For TPMS service, that means the sensor is engineered to work with the vehicle’s factory monitoring logic rather than forcing a universal setup. This matters on Subaru TPMS applications where system communication, relearn behavior, and sensor identification must remain consistent. Part number 550-2701 is a direct-fit solution for Subaru owners servicing OE-style TPMS systems.

This part cross-references Subaru 28103AG00A and 28103AG00B for the same application.

Vehicle Fitment

• Fits 2008-2011 Subaru Tribeca, N/A — 315 MHz, clamp in, 66 in-lbs / 7.5 N.m; OE Manufactured
• Fits 2004-2008 Subaru Legacy, N/A — 315 MHz, clamp in, 66 in-lbs / 7.5 N.m; OE Manufactured
• Fits 2006-2007 Subaru B9 Tribeca, N/A — 315 MHz, clamp in, 66 in-lbs / 7.5 N.m; OE Manufactured
• Fits 2004-2007 Subaru Outback, N/A — 315 MHz, clamp in, 66 in-lbs / 7.5 N.m; OE Manufactured

What It Helps Address

• TPMS warning light caused by a failed sensor
• Loss of tire pressure signal on Subaru 315 MHz systems
• Incorrect or missing tire pressure readings
• Service issues after wheel or tire replacement
• Factory TPMS functions not operating as expected

Installation Notes

Installation requires a clamp-in TPMS setup and proper torque during wheel service. After installation, the vehicle may require a TPMS relearn procedure according to the manufacturer’s process. Denso notes that some do-it-yourself installations may still need a trusted repair shop to complete relearn and system registration.

Quality Assurance

Denso designs this TPMS sensor for direct use with the vehicle’s original TPMS system and to maintain factory diagnostic capability. The OE Manufactured construction supports Subaru applications that rely on stable sensor communication and preserved system functions.
