Walker 225-1436 Manifold Absolute Pressure Sensor
Walker MAP Sensor for Subaru Legacy and Outback
Walker Products 225-1436 is a Manifold Absolute Pressure (MAP) sensor built as an OE replacement for Subaru engine management systems. It measures intake manifold pressure and sends that signal to the ECM so fuel delivery and ignition timing can be adjusted for proper drivability, fuel economy, and emissions control.
Walker Sensor Only products focus on the sensor component itself, with OE-style electrical output and connector fit for straightforward replacement on Subaru Legacy and Subaru Outback applications.
Key Features
- Manifold Absolute Pressure sensor for intake manifold pressure monitoring
- OE replacement design for electrical output, pressure range, and connector fit
- Black plastic housing with oval female connector
- 3 blade terminals, plug-in fitting, 1 port
- Built for high engine bay temperatures, vibration, and intake air contaminants
- Fits 2010-2012 Subaru Legacy, N/A
- Fits 2005 Subaru Legacy, N/A, from 08/02/2004
- Fits 2005 Subaru Outback, N/A, from 08/02/2004
Detailed Description
The Walker 225-1436 MAP sensor helps the ECM calculate engine load by reading manifold pressure in real time. That signal is critical for fuel injection control, ignition timing, and emissions performance on gasoline and diesel engine management systems. This replacement sensor is engineered to match OE specifications for fit and signal output, making it a direct choice for Subaru Legacy and Subaru Outback service work where the original MAP sensor has failed or drifted out of range.
This part cross-references DENSO Auto Parts 198-0001 for the same application.
Common Issues This Part Can Help Address
- Check engine light related to MAP sensor performance
- Rough idle or unstable engine operation
- Poor throttle response or reduced power
- Incorrect fuel mixture caused by inaccurate manifold pressure readings
- Emissions or drivability concerns tied to engine load calculation
Installation Notes and Tips
Verify connector shape, terminal count, and port layout before installation. This Walker MAP sensor uses a black oval female connector with 3 male blade terminals and a plug-in fitment, so matching the original connector and mounting style is important for proper installation. Confirm the vehicle build date for 2005 Subaru Legacy and 2005 Subaru Outback applications noted from 08/02/2004.
Quality Assurance
Walker Products manufactures this MAP sensor to OE-level specifications for electrical performance, pressure range, and connector fit. Each unit is tested for accuracy and responsiveness to support reliable engine control operation.
