Standard Ignition AS461 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor for BMW Applications

Standard Ignition AS461 is a manifold absolute pressure sensor built for BMW engines that rely on accurate intake manifold pressure data for fuel and boost control. It features a 4-terminal blade-style connection, a single plug-in connector, and an included O-ring for a secure seal at the mounting point.

Compatible With BMW X5, X6, X7, XM, 760i xDrive, M8, M5, M550i xDrive, 750i xDrive, M760i xDrive, 530i, 540i, 320i, 328i, 335i, 528i, 535i, 550i, X3, X4, X1, Z4, and other listed BMW models across 2009-2025 applications. This part number, AS461, is also cross-referenced to Continental 5WK96857Z for the same application.

• Manifold Absolute Pressure Sensor for intake manifold pressure monitoring
• 4-terminal, male blade terminals with one female plug-in connector
• Round and rectangular connector shape for listed BMW applications
• Black finish with one vacuum port
• O-ring included; hardware, bracket, and wiring harness not included

Detailed Product Overview

AS461 is used in BMW emission control and engine management systems where manifold pressure data is needed for proper air-fuel calculation and load sensing. The sensor’s sealed design, single vacuum port, and included O-ring support a direct replacement on vehicles such as the BMW X5, X6, and 5 Series models listed in the fitment data. Standard Ignition AS461 is also listed with interchange references including Delphi PS20064, Hella 358152381, and Walker Products 225-1282.

What This Sensor Helps Address

• Check engine lights related to manifold pressure signal faults
• Rough idle or unstable engine load readings
• Hard starting or poor throttle response tied to intake pressure input
• Incorrect fuel delivery caused by inaccurate MAP sensor data
• Driveability issues on BMW turbocharged and naturally aspirated applications

Installation Notes and Tips

Verify connector style, terminal count, and vacuum port location before installation. This sensor uses a plug-in connector and does not include a wiring harness, mounting bracket, or hardware. Confirm the vehicle-specific notes in the fitment list, including applications located on the air cleaner housing or intake manifold, and replace the O-ring seal during service if the original seal is worn or damaged.

Quality Assurance

Standard Ignition supplies AS461 as an OE-style replacement sensor for listed BMW applications. Confirm fitment by year, model, and location notes before ordering to ensure the correct manifold absolute pressure sensor for your vehicle.
