Walker 225-1317 Manifold Absolute Pressure Sensor

Walker MAP Sensor for Ford Focus

Walker Products Part Number 225-1317 is a sensor-only manifold absolute pressure sensor built for OE replacement service. It measures intake manifold pressure and sends that data to the ECM so fuel delivery and ignition timing can be adjusted for proper engine load control, drivability, and emissions performance.

Compatible With 2012-2018 Ford Focus applications, this Walker MAP sensor is engineered for direct electrical and connector fit. The black plastic housing, oblong female connector, blade terminals, and plug-in design support straightforward replacement on the vehicle’s existing harness.

Product Details

Walker Sensor Only line focuses on replacement sensors that match OE electrical output, pressure range, and connector fit. This MAP sensor is used across gasoline and diesel engine management systems, where accurate manifold pressure data helps the ECM calculate engine load and maintain stable fuel injection and ignition timing. For Ford Focus owners searching for a Ford Focus MAP sensor, intake manifold pressure sensor, or Walker 225-1317 replacement, this part provides a direct-fit service solution.

This part cross-references Standard Ignition AS617 for the same application.

Common Issues It Can Help Resolve

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine operation
• Hesitation during acceleration
• Poor fuel economy caused by incorrect load readings
• Emissions or drivability concerns tied to manifold pressure data

Installation Notes and Tips

Verify the connector shape, terminal count, and port layout before installation. Inspect the intake manifold connection point and harness terminals for contamination, damage, or looseness before plugging in the new sensor. Clear diagnostic trouble codes after replacement and confirm proper engine operation with a scan tool if available.
