Delphi PS20124 Manifold Absolute Pressure Sensor

Delphi MAP Sensor PS20124 for BMW

The Delphi PS20124 manifold absolute pressure sensor delivers OE-standard voltage-based pressure readings for precise engine management. Built for a wide range of BMW applications, it supports accurate intake manifold pressure data that the engine control system uses for fueling and load calculations.

• Manifold Absolute Pressure Sensor for emission control and engine management systems
• 5-volt, voltage-type sensor with a 4-pin male terminal design
• Standard replacement grade with a bolt-on mount
• Black oval connector, black housing, and plastic body construction
• 1 connector, 1 port, and no wiring harness included
• Tested and calibrated to OE standards for consistent readings

Detailed Product Overview

Delphi PS20124 is a manifold absolute pressure sensor engineered to provide accurate manifold pressure input across many BMW turbocharged and performance-oriented platforms. The sensor uses a 5-volt voltage signal and a single-port, bolt-on design with a black oval connector and 4 male terminals. Delphi validates and calibrates its sensors to OE standards, helping maintain reliable signal output for the engine control module. This part cross-references Standard Ignition AS652 for the same application.

Compatible With BMW 330i, BMW 430i, BMW 530i, BMW X3, BMW X4, BMW Z4, BMW 740i, BMW M340i, BMW X5, BMW X6, and other listed BMW models. The Delphi PS20124 is also a direct-fit option for BMW 330e, 430i Gran Coupe, 530e, 840i, M3, M4, M440i, X7, and related applications shown in the fitment data.

What This MAP Sensor Helps Address

• Incorrect manifold pressure readings
• Rough idle caused by inaccurate load data
• Driveability issues tied to faulty sensor output
• Check engine lights related to MAP sensor performance
• Fueling and throttle response problems from inconsistent intake pressure signals

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. This sensor uses a bolt-on mounting design, a single connector, and no included wiring harness. Confirm the vehicle’s original sensor matches the 5-volt voltage-type configuration and the listed BMW fitment before replacement. For best results, inspect the intake tract and electrical connector for damage or contamination during service.

Quality Assurance

Delphi backs this MAP sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for accurate readings. That level of validation supports dependable sensor output across the listed BMW applications, including BMW 330i, BMW 530i, BMW X3, and other compatible models.
