Walker 225-1272 Manifold Absolute Pressure Sensor

Walker Sensor Only MAP Sensor for OE Replacement

Walker Products Part Number 225-1272 is a Manifold Absolute Pressure (MAP) sensor built as an OE replacement for vehicles that rely on accurate intake pressure data for engine control. It measures pressure in the intake manifold and sends that signal to the ECM so fuel delivery and ignition timing stay aligned with engine load.

This Sensor Only line from Walker focuses on direct-fit electrical and connector compatibility for clean integration with the factory system. It is a practical choice for Audi Q5, Audi S4, Audi S5, Audi A6 Quattro, and related supercharger air outlet pressure sensor applications.

Key Features

• Manifold Absolute Pressure sensor for engine load calculation
• OE replacement design for factory-style electrical output and pressure range
• Black oval female connector with 4 male terminals
• Plug-in fitting type with 1 connector and 1 port
• Plastic body built for engine bay heat and vibration exposure
• Walker Sensor Only line for direct replacement applications

Detailed Description

Walker 225-1272 is engineered to match OE specifications for signal output, connector fit, and pressure response. In turbocharged and supercharged systems, the MAP sensor helps the ECM interpret manifold pressure changes so the engine can adjust fueling and spark timing with the correct data. This supports stable drivability, emissions control, and consistent performance across gasoline and diesel platforms.

This part cross-references Bosch 0261230214 for the same application. It also cross-references Standard Ignition AS448 for the same application. For buyers searching for a MAP sensor for 2010-2016 Audi S4, 2010-2016 Audi S5, or 2013-2017 Audi Q5, Part Number 225-1272 provides a direct replacement path.

What It Helps Address

• Check engine light related to manifold pressure sensor faults
• Rough idle or inconsistent throttle response
• Incorrect fuel trim or load calculation
• Reduced power from inaccurate boost or manifold pressure readings
• Emissions performance issues tied to sensor signal errors
