Walker MAP Sensor for Engine Management

Walker Products 225-1008 is a manifold absolute pressure sensor built for emission control and engine management applications. It uses a 3-terminal bullet connection with a rectangular female connector, making it a direct-fit style replacement for many GM, Buick, Pontiac, Chevrolet, GMC, Oldsmobile, Geo, and Isuzu applications.

Walker Products has supplied fuel system and engine sensor components since 1946, with manufacturing and engineering support focused on meeting or exceeding OEM standards. The Walker Products line includes sensors and other engine management parts for vehicles that need accurate signal input for proper drivability.

Key Features

  • Manifold Absolute Pressure Sensor for engine load signal input
  • Part number 225-1008 for catalog and fitment lookup
  • 3-terminal bullet design with rectangular female connector
  • Female connector and female terminal configuration
  • Built for emission control and engine sensor replacement needs
  • Walker Products manufacturing backed by ISO 9001/IATF16949 certification

Detailed Description

This Walker MAP sensor is used to measure intake manifold pressure so the engine control system can calculate load and adjust fuel delivery and timing. It is listed for a wide range of vehicles, including Buick Regal, Pontiac Grand Prix, Chevrolet Express 2500, GMC Savana 3500, Chevrolet Tahoe, and GMC Yukon applications. If you are replacing a failing MAP sensor on a Buick Regal or Chevrolet Tahoe, Walker Products 225-1008 provides a cataloged replacement option with the correct connector style and terminal layout.

This part cross-references Bosch 18003 and Standard Ignition AS4 for the same application.

What It Helps Fix

  • Rough idle caused by incorrect manifold pressure readings
  • Hard starting related to inaccurate engine load data
  • Hesitation or poor throttle response during acceleration
  • Check engine light conditions tied to MAP sensor faults
  • Fuel trim issues from unstable sensor output

Installation Notes and Tips

Verify connector shape, terminal count, and terminal gender before installation. This sensor uses a rectangular female connector with 3 bullet terminals, so matching the harness connection is important for proper fitment. Confirm the vehicle application against the listed year and model before replacing the original sensor.

Quality Assurance

Walker Products manufactures engine sensors to meet or exceed OEM standards and specifications. The company supports its parts with in-house manufacturing, product management, engineering, and technical support, and operates as an ISO 9001/IATF16949 certified manufacturer.
