Standard Ignition AS703 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor for Ford and Lincoln

Standard Ignition AS703 is a manifold absolute pressure sensor built for direct engine management signal input on select Ford and Lincoln vehicles. It uses a female connector with a bolt-on connector type and 3 male blade terminals for a secure electrical connection at the intake manifold.

Key Features

• Manifold Absolute Pressure Sensor for emission control and engine load monitoring
• Female connector, 1 connector, bolt-on connector type
• 3 male blade terminals for the vehicle harness connection
• Direct-fit replacement for intake manifold mounting locations
• Standard Ignition AS703 for select Ford Bronco, Bronco Sport, Edge, Explorer, F-150, Ranger, Escape, Mustang, Lincoln Corsair, and Nautilus applications

Detailed Description

This Standard Ignition AS703 manifold absolute pressure sensor measures intake manifold pressure so the engine control system can calculate load and adjust fuel delivery and ignition timing. It is a fitment-based replacement for 2019-2024 Ford and Lincoln applications, including Ford Bronco, Bronco Sport, Edge, Explorer, F-150, Ranger, Escape, Mustang, and Lincoln Corsair and Nautilus models. This part cross-references K2GZ9F479A and EC2205 for the same application.

Use AS703 when servicing a MAP sensor mounted on the intake manifold and you need a replacement that matches the vehicle’s electrical and mounting style. The part number AS703 is also a useful search term for Ford Bronco Sport MAP sensor, Ford Explorer intake manifold pressure sensor, and Lincoln Corsair manifold absolute pressure sensor replacement.

What It Helps Fix

• Erratic idle caused by inaccurate manifold pressure readings
• Check engine light related to MAP sensor performance
• Hard starting or rough running from incorrect engine load data
• Reduced throttle response from faulty intake manifold pressure input
• Fuel trim issues caused by a failing pressure sensor
