Walker 225-1348 Manifold Absolute Pressure Sensor

Walker MAP Sensor for Subaru Legacy and Outback

Walker Products Sensor Only MAP Sensor 225-1348 is an OE replacement manifold absolute pressure sensor for select 2005 Subaru Legacy and 2005 Subaru Outback applications built to 08/01/2004. It measures intake manifold pressure and sends that signal to the ECM so the engine can calculate load and manage fuel and ignition settings.

Built with a black oval connector, 3 blade terminals, a female plug-in connection, and a plastic body, this Walker MAP sensor is made for direct electrical and connector fit on the listed Subaru applications.

Sensor Only Product Line

Walker Products Sensor Only focuses on replacement sensors that match OE-style electrical output, pressure range, and connector design. For drivers replacing a failed MAP sensor on a Subaru Legacy or Subaru Outback, this line provides a direct-fit sensor solution without unnecessary extras.

Key Features

• Part number 225-1348 MAP sensor for select Subaru applications
• OE replacement design for intake manifold pressure measurement
• Black oval connector with 1 connector, 3 blade terminals
• Female plug-in fitting for direct connection
• Plastic sensor body engineered for engine bay conditions
• Cross-reference: Standard Ignition AS659

Detailed Description

Walker 225-1348 is a manifold absolute pressure sensor that reports intake manifold pressure to the ECM, helping the engine manage load calculation, fuel delivery, ignition timing, power output, fuel economy, and emissions control. It is built for the 2005 Subaru Legacy and 2005 Subaru Outback, both with the notes listed for manifold vacuum sensor service through 08/01/2004. This part cross-references Standard Ignition AS659 for the same application.

Common Issues This Part Can Address

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine operation
• Incorrect fuel mixture or poor throttle response
• Reduced fuel economy caused by inaccurate manifold pressure data
• Driveability concerns tied to engine load calculation errors

Installation Notes and Tips

Verify the connector shape, terminal count, and port configuration before installation. This part uses a plug-in fitment with a female connector and 3 male blade terminals, so the vehicle harness must match the listed configuration. Confirm the vehicle is a 2005 Subaru Legacy or 2005 Subaru Outback with the applicable build date note before replacing the sensor.

Quality Assurance

Walker Products designs this MAP sensor to OE specifications for electrical output, pressure range, and connector fit, then tests it for accuracy, responsiveness, and long-term reliability. It is engineered to withstand heat, vibration, and intake air contaminants commonly found in the engine bay.
