Walker 1007-1005 Manifold Absolute Pressure Sensor - Manifold

Walker 1007-1005 MAP Sensor Overview

Walker 1007-1005 is an OE replacement manifold absolute pressure sensor built to measure intake manifold pressure and send that signal to the engine control module. That data helps the ECM calculate engine load and adjust fuel delivery and ignition timing for stable drivability, fuel efficiency, and emissions control.

Compatible With gasoline and diesel engine management systems, this Walker MAP sensor is engineered for electrical output, pressure range, and connector fit that match OE requirements. It is a direct-fit service part for vehicles that need accurate manifold pressure feedback, including applications such as Ford F-150 and Dodge Ram 2500 where MAP sensor performance affects engine response.

Key Features

• OE replacement manifold absolute pressure sensor
• Measures intake manifold pressure for ECM load calculation
• Supports fuel injection and ignition timing control
• Gray connector with circular shape for a direct electrical interface
• 3-terminal, female connector with male terminals
• Built for high engine bay temperatures, vibration, and intake air contaminants
• Walker 1007-1005 is tested for accuracy and responsiveness

Detailed Description

The Walker 1007-1005 MAP sensor is designed to restore the pressure signal the ECM relies on for engine management. By reporting manifold pressure accurately, it helps maintain proper air-fuel strategy and timing control across a wide range of operating conditions. This makes it a practical replacement when diagnosing drivability concerns or emissions-related faults on Ford F-150 and Dodge Ram 2500 platforms.

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

Common Issues This Part Can Address

• Check engine light related to manifold pressure signal faults
• Rough idle or unstable engine speed
• Hesitation, poor throttle response, or reduced power
• Incorrect fuel mixture or timing control
• Emissions performance problems tied to MAP sensor readings

Installation Notes and Tips

Verify the connector style before installation: gray color, circular shape, 1 connector, 3 terminals, female connector gender, and male terminal gender. Inspect the intake tract and electrical connector for contamination, corrosion, or damaged pins before replacing the sensor. Clear diagnostic trouble codes after installation and confirm live data readings during a road test.

Quality Assurance

Walker Products engineers this MAP sensor to meet OE specifications for output, pressure range, and connector fit. Each unit is tested for accuracy and long-term reliability to support consistent engine control performance.
