Delphi PS20068 Manifold Absolute Pressure Sensor

Delphi PS20068 is a standard replacement manifold absolute pressure sensor built for accurate engine load and intake pressure readings. It is a 5-volt, 3-terminal sensor with a square, single-connector design and bolt-on mounting for service on select Mercedes-Benz applications.

Compatible With Mercedes-Benz models including C350, E350, ML350, R350, SLK350, and S65 AMG applications, this Delphi MAP sensor supports precise signal output for drivability-focused repairs. The PS20068 is also cross-referenced to Standard Ignition AS450 for the same application.

Key Features

• Manifold Absolute Pressure Sensor for emission control and engine management systems
• 5-volt voltage type with 3 blade terminals
• Single square male connector, black housing, black connector color
• Bolt-on mount with plastic body construction
• Standard replacement grade for direct service use
• OE-standard testing and calibration for accurate readings
• Fits a wide range of Mercedes-Benz vehicles from 1998-2020

Detailed Description

Delphi PS20068 is engineered to deliver stable MAP sensor output for Mercedes-Benz engines that rely on accurate manifold pressure data for fuel delivery, load calculation, and overall engine control. Delphi validates and calibrates its sensors to OE standards, helping ensure consistent readings across the supported vehicle range. This part number, PS20068, is used on applications such as Mercedes-Benz C280, C240, E55 AMG, CLK55 AMG, GLK350, and Maybach S600 models.

This part cross-references Standard Ignition AS450 for the same application.

What It Helps Address

• Rough idle caused by incorrect manifold pressure input
• Hesitation or poor throttle response from faulty sensor readings
• Check engine light concerns related to MAP sensor performance
• Incorrect fuel trim behavior tied to intake pressure signal errors
• Driveability issues on Mercedes-Benz C350, E350, ML350, and related models

Installation Notes and Tips

Verify connector shape, terminal count, and mount style before installation. This sensor uses a single square connector, 3 terminals, and bolt-on mounting. Confirm the vehicle application by year, make, and model before replacing the original unit, and inspect the connector and wiring for damage that could affect sensor readings.

Quality Assurance

Delphi sensors are developed with OE-focused validation methods and tested to OE standards for accurate output. That calibration process supports dependable service on supported Mercedes-Benz applications and helps reduce repeat repairs.
