Walker 225-1432 Manifold Absolute Pressure Sensor

Walker 225-1432 MAP Sensor Overview

Walker 225-1432 is a manifold absolute pressure sensor built as an OE replacement for modern engine management systems. It measures intake manifold pressure and sends that signal to the ECM so fuel delivery and ignition timing can be adjusted for consistent drivability, fuel economy, and emissions control.

Compatible With Ford Bronco, Bronco Sport, Edge, Escape, Explorer, Mustang, Ranger, and Lincoln Corsair and Nautilus applications listed below, this Walker Sensor Only part is engineered for direct electrical and connector fit. The Sensor Only line focuses on replacement sensors that match OE-style requirements for integration and response.

Key Features

• Manifold Absolute Pressure (MAP) sensor for intake manifold pressure measurement
• 5-volt electrical system with 4 blade terminals
• Black oval female connector with 1 connector and 1 port
• Bolt-on mount with plug-in fitting type
• Black plastic housing for underhood use
• OE replacement design for electrical output, pressure range, and connector fit
• Built for gasoline and diesel engine management systems

Detailed Product Description

Walker Products Part Number 225-1432 is designed to replace a failed MAP sensor with a unit that matches OE specifications for signal output and physical connection. By reporting manifold pressure to the ECM, the sensor helps the engine computer calculate load and manage injection and timing. That function is central to stable idle quality, throttle response, and emissions performance. This part cross-references Standard Ignition AS703 for the same application.

Walker Sensor Only parts are focused replacement components for vehicles that need the sensor itself, without extra hardware. For Ford Bronco, Ford Bronco Sport, Ford Edge, Ford Escape, Ford Explorer, Ford Mustang, Ford Ranger, Lincoln Corsair, and Lincoln Nautilus fitments, 225-1432 is built to integrate with the existing system layout and connector style.

What It Can Help Resolve

• Check engine light related to MAP sensor performance
• Rough idle or unstable engine operation
• Poor throttle response or hesitation
• Incorrect fuel mixture or load calculation
• Reduced fuel economy or emissions-related drivability concerns

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. This sensor uses a black oval female connector, 4 male blade terminals, and a bolt-on mounting design. Confirm the vehicle application by year, make, and model before replacement, and inspect the intake tract for contamination or vacuum-related issues that could affect sensor readings.
