Walker 225-1408 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor 225-1408

Walker Products 225-1408 is a Sensor Only manifold absolute pressure sensor built as an OE replacement for precise intake manifold pressure measurement. It sends accurate pressure data to the ECM so engine load, fuel delivery, and ignition timing can be managed correctly on Porsche applications.

Compatible With Porsche 911, Cayenne, Boxster, Cayman, and Panamera applications, this Walker MAP sensor is engineered to match OE electrical output, pressure range, and connector fit. The black oval female connector, 4 blade terminals, plug-in design, and plastic body support direct replacement on the listed vehicles.

Detailed Description

Walker Sensor Only is the product line for replacement sensors supplied without extra assembly components, keeping the focus on the sensor itself. Part number 225-1408 is a manifold absolute pressure sensor that measures intake manifold pressure and relays that information to the ECM. On Porsche 911, Cayenne, Boxster, Cayman, and Panamera models, that signal helps the engine computer calculate load and adjust fuel injection and ignition timing for stable drivability and emissions control.

This part cross-references Bosch 0261230247 for the same application. It is also referenced against 0906186 and 94860618000.

What It Helps Address

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine load readings
• Hesitation during acceleration
• Fuel trim issues caused by inaccurate manifold pressure data
• Reduced fuel economy from incorrect ECM input

Installation Notes and Tips

Fits 2012-2019 Porsche 911, N/A; Fits 2011-2018 Porsche Cayenne, N/A; Fits 2013-2016 Porsche Boxster, N/A; Fits 2014-2016 Porsche Cayman, N/A; Fits 2010-2016 Porsche Panamera, N/A; Fits 2011 Porsche 911, N/A, from engine # 03675; Sensor Only. Verify connector shape, terminal count, and port layout against the original sensor before installation. Clear diagnostic trouble codes after replacement and confirm the ECM reads manifold pressure correctly during a road test.

Quality Assurance

Walker Products designs this MAP sensor to OE specifications and tests it for accuracy, responsiveness, and long-term reliability. The sensor is built to withstand heat, vibration, and intake contamination common in modern engine bays.
