Walker 225-1205 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor for Subaru

Walker Products Part Number 225-1205 is a Manifold Absolute Pressure (MAP) sensor built as an OE replacement for select Subaru applications. It measures intake manifold pressure and sends that signal to the engine control module so fuel delivery and ignition timing can be adjusted for proper engine load control, drivability, and emissions performance.

The Sensor Only line focuses on direct-fit replacement sensors with OE-style electrical output, pressure range, and connector fit. For Subaru Legacy, Outback, Tribeca, and B9 Tribeca applications, this Walker MAP sensor is built for the connector and mounting requirements used on the listed vehicles.

• OE replacement Manifold Absolute Pressure Sensor
• Black connector with oval shape
• 1 female connector, 4 male blade terminals
• Plug-in fitting with 1 port
• Plastic body construction
• Engineered for accurate pressure signal response

Detailed Product Overview

Walker 225-1205 is a MAP sensor replacement for vehicles that rely on manifold pressure data to manage engine load. It is used on 2013-2014 Subaru Legacy, 2013-2014 Subaru Outback, 2011-2014 Subaru Tribeca, 2008-2009 Subaru Tribeca, 2006-2007 Subaru B9 Tribeca, and 2005 Subaru Outback with the noted manifold vacuum sensor application. This part number 225-1205 is also cross-referenced to Standard Ignition AS351 for the same application.

Walker Products designs this Sensor Only MAP sensor to meet OE specifications for electrical output, pressure range, and connector fit, helping maintain proper communication between the sensor and ECM. The result is a direct replacement option for Subaru Legacy and Subaru Outback MAP sensor service, as well as Tribeca and B9 Tribeca manifold pressure sensor replacement needs.

Common Issues This Sensor Can Address

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine speed
• Incorrect fuel mixture or fuel trim concerns
• Reduced throttle response or drivability complaints
• Manifold vacuum signal faults on listed Subaru applications

Installation Notes and Tips

Verify connector style, terminal count, and mounting style before installation. This sensor uses a black oval female connector with four male blade terminals and a plug-in fitment. Confirm the vehicle application by year, make, model, and engine management configuration before replacing the original MAP sensor.

Quality Assurance

Walker Products builds this MAP sensor to OE-level specifications and tests it for accuracy, responsiveness, and long-term reliability. The Sensor Only line is intended to provide a direct replacement sensor that integrates with the vehicle’s existing engine management system.
