Walker 225-1286 Manifold Absolute Pressure Sensor
Walker MAP Sensor for Subaru Applications
Walker Products 225-1286 is a manifold absolute pressure sensor built for OE-style replacement on select Subaru vehicles. It measures intake manifold pressure and sends that data to the ECM so fuel delivery and ignition timing can be adjusted for proper engine operation.
Compatible With 2015 Subaru WRX STI and 2008-2012 Subaru Impreza, this Walker Sensor Only MAP sensor is built around the connector, terminal, and body details needed for direct replacement service. The 225-1286 part number is also a useful reference when matching the correct sensor for Subaru WRX STI and Subaru Impreza applications.
Key Features
- Manifold Absolute Pressure (MAP) sensor for engine load input
- OE replacement design for electrical output, pressure range, and connector fit
- Black female connector with oblong shape
- 4 blade terminals with plug-in fitting type
- Plastic body construction with 1 port
- Built for gasoline and diesel engine management systems
Product Details
Walker Products Sensor Only line focuses on replacement sensors that match original equipment requirements for fit and signal performance. Part number 225-1286 is engineered to communicate manifold pressure data to the ECM, helping the engine management system calculate load and respond with the correct fuel and ignition strategy. That makes it a direct-fit choice for Subaru WRX STI and Subaru Impreza MAP sensor replacement work where accurate pressure feedback matters.
This part cross-references NTK MA0046 and Standard Ignition AS466 for the same application.
Common Issues This Sensor Can Address
- Check engine light related to MAP sensor circuit or pressure signal faults
- Rough idle or unstable engine speed
- Poor throttle response during acceleration
- Incorrect fuel mixture caused by inaccurate manifold pressure readings
- Reduced fuel economy or drivability concerns tied to engine load calculation
Installation Notes
Verify connector shape, terminal count, and port layout before installation. This MAP sensor uses a plug-in design with a female connector and blade terminals, so the replacement should match the original electrical interface on the vehicle. Confirm the application by year, make, and model before ordering, especially for 2015 Subaru WRX STI and 2008-2012 Subaru Impreza service.
Quality Assurance
Walker Products designs this MAP sensor to OE specifications for output, pressure range, and connector fit, with testing focused on accuracy, responsiveness, and long-term reliability in the engine bay environment.
