Walker 225-1438 Manifold Absolute Pressure Sensor

Walker MAP Sensor for Mini Cooper

Walker Products Part Number 225-1438 is an OE replacement manifold absolute pressure sensor for select 2013-2014 Mini Cooper 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.

Walker Sensor Only line parts focus on direct sensor replacement for vehicles that need accurate signal output and connector fit. This Walker MAP sensor is built for the Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman platforms listed below.

Key Features

• Manifold Absolute Pressure (MAP) sensor for intake manifold pressure measurement
• OE replacement design for electrical output, pressure range, and connector fit
• Black plastic body with a female connector
• Oblong connector shape with 1 connector, 3 terminals, and pin terminal type
• Built for high engine bay temperatures, vibration, and intake air contaminants
• Walker Part Number 225-1438 for direct identification

Detailed Description

The Walker Products Sensor Only line provides replacement MAP sensors engineered for stable signal delivery to the ECM. On 2013-2014 Mini Cooper, Mini Cooper Countryman, and Mini Cooper Paceman models, the MAP sensor plays a direct role in engine load calculation, fuel control, ignition timing, drivability, fuel economy, and emissions performance. Part Number 225-1438 is built to match OE specifications so the sensor integrates with the factory harness and engine management system.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light related to manifold pressure signal faults
• Rough idle or unstable engine operation
• Poor fuel economy caused by incorrect load readings
• Hesitation, stumble, or reduced throttle response
• Emissions performance issues tied to inaccurate MAP data

Installation Notes and Tips

Verify connector shape, terminal count, and body style against the original sensor before installation. Confirm the vehicle application by year, make, and model: Fits 2013-2014 Mini Cooper, N/A; Fits 2013-2014 Mini Cooper Countryman, N/A; Fits 2013-2014 Mini Cooper Paceman, N/A. Inspect the intake tract and electrical connector for contamination or damage before replacing the sensor. Clear diagnostic trouble codes after installation and confirm the ECM reads a stable manifold pressure signal.

Quality Assurance

Walker Products manufactures this MAP sensor as an OE replacement component with attention to electrical output, pressure range, and connector fit. Part Number 225-1438 is tested for accuracy, responsiveness, and long-term reliability in demanding engine bay conditions.
