Detailed Description

AS742 is a manifold absolute pressure sensor used to monitor intake manifold pressure for engine management systems. On applications such as the Ford F-150, Ford Bronco, and Lincoln Corsair, accurate MAP sensor input supports proper fuel and ignition control by helping the engine computer interpret manifold vacuum and load conditions. The connector design includes a female plug with four blade terminals, which helps ensure correct electrical interface when replacing the original sensor. Part number AS742 also cross-references 2-27481 and EC2262 for the same application.

What It Is Used For

• Restoring accurate manifold pressure signal output
• Addressing drivability issues tied to incorrect air-load readings
• Replacing a failed sensor with the correct connector style
• Supporting engine control on Ford and Lincoln vehicles with listed fitment

Installation Notes and Tips

Verify connector shape, terminal count, and fitment before installation. This sensor uses a plug-in attachment method and an oval connector, so the replacement should match the original electrical interface exactly. Confirm the application notes for the 2024 Ford Escape, which lists an intake manifold mounting note. Professional installation and a scan-tool check after replacement are recommended when diagnosing MAP-related faults.

Quality Assurance

Standard Ignition supplies replacement engine management components for a wide range of automotive applications. AS742 is built to match the listed connector and terminal configuration for the specified vehicles.
