Product Details

The Walker Products 225-1300 MAP sensor is designed for vehicles that rely on manifold pressure data to calculate load, timing, and fueling. In select Mercedes-Benz C250 and Mercedes-Benz SLK250 applications, this sensor helps the engine control system read intake conditions accurately so the vehicle can maintain proper drivability and emissions performance. Walker Products has supplied fuel system and engine sensor components since 1946, and its Walker Products line focuses on OE-style replacement parts for modern engine management systems.

This part cross-references Bosch 0261230250 for the same application.

What It Helps Address

• Check engine light related to manifold pressure sensor performance
• Rough idle caused by incorrect intake manifold pressure readings
• Hesitation or poor throttle response under acceleration
• Incorrect fuel delivery calculations from faulty load input
• Driveability issues tied to unstable engine sensor signals

Installation Notes and Fitment

• Fits 2012-2015 Mercedes-Benz C250, N/A
• Fits 2012-2015 Mercedes-Benz SLK250, Location - Throttle Body
• Fits 2012-2015 Mercedes-Benz SLK250, Location-Engine Intake Manifold
• Verify the sensor location on the vehicle before ordering, since SLK250 applications are listed in two mounting locations.
• Confirm connector style and OE part number against the original sensor for proper application matching.
