Delphi PS20072 Manifold Absolute Pressure Sensor

Delphi MAP Sensor PS20072 for Mercedes-Benz

Delphi PS20072 is a manifold absolute pressure sensor built for accurate engine load and intake pressure readings. It is a standard replacement part with OE-style validation, making it a direct choice for Mercedes-Benz applications that rely on precise sensor input for drivability and emissions control.

Key Features

• Manifold Absolute Pressure Sensor for voltage-based signal output
• Standard replacement grade for OE-style service
• 1 black rectangular connector with 3 male terminals
• 1-port, bolt-on design with black plastic housing
• Maximum pressure reading: 2.0 / 35.0
• Delphi-tested and calibrated to OE standards

Detailed Description

The Delphi PS20072 MAP sensor is engineered to provide accurate manifold pressure data to the engine control system. That signal helps the ECU calculate air density and load, which is critical for smooth throttle response, stable idle quality, and proper fuel delivery. Delphi validates and calibrates its sensors to OE standards, supporting consistent readings and reducing repeat repairs. This part cross-references Standard Ignition AS489 for the same application. Common Mercedes-Benz fitments include SL550, S550, E550, CLS550, GL550, and ML550, along with AMG variants such as SL63 AMG, S63 AMG, and G63 AMG. If you are replacing a Mercedes-Benz MAP sensor, Delphi PS20072 offers a direct service solution for a wide range of 2011-2019 vehicles.

What It Helps Solve

• Rough idle caused by inaccurate manifold pressure input
• Hesitation or poor throttle response under acceleration
• Incorrect fuel mixture calculations from faulty sensor data
• Check engine light concerns related to MAP sensor performance
• Driveability issues tied to unstable engine load readings

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a bolt-on mount, a single port, and a 3-terminal male connector, so matching the original configuration is important for proper fitment. Confirm the vehicle application against the listed Mercedes-Benz models, including 2011-2019 coverage across SL550, S550, E550, CLS550, GL550, ML550, and related AMG models. For best results, inspect the intake connection and wiring connector for damage before installing the new sensor.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for accurate readings. That focus on calibration helps support dependable sensor output in Mercedes-Benz engine management systems.
