Spectra MP158 Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor Overview

The Spectra MP158 manifold absolute pressure sensor is built to meet or exceed OE specifications for fit, form, and function. It is a direct replacement style sensor for a wide range of Mercedes-Benz, Freightliner, Dodge, Chrysler, and Jeep applications, including Mercedes-Benz S-Class, E-Class, and Sprinter fitments.

Key Features

• OE-spec replacement for manifold absolute pressure sensing
• Engineered for proper fit, form, and function
• Supports accurate intake manifold pressure signal reporting
• Fits a broad range of Mercedes-Benz and related platform applications
• Part number MP158 for catalog and service reference

Detailed Description

The Spectra MP158 is a manifold absolute pressure sensor designed for vehicles that rely on precise manifold pressure input for engine management. This sensor is listed for numerous Mercedes-Benz models, including S-Class, E-Class, C-Class, ML-Class, GL-Class, SL-Class, and Sprinter applications, along with select Chrysler Crossfire, Dodge Sprinter, and Jeep Liberty fitments. The MP158 part number is useful when matching the correct replacement during diagnosis or service, and MP158 also cross-references Standard Ignition AS359 for the same application.

Compatible With Mercedes-Benz S-Class, E-Class, and Sprinter applications, this sensor supports replacement of a failed MAP sensor without changing the original fitment profile. It is also listed for Mercedes-Benz C250, E350, GL350, and Sprinter 2500 applications, as well as other long-tail fitment combinations shown in the catalog data.

What It Is Used For

• Replacing a faulty manifold absolute pressure sensor
• Restoring proper manifold pressure signal input to the engine control system
• Addressing drivability issues tied to incorrect pressure readings
• Correcting sensor-related fault codes during diagnosis
• Returning the vehicle to OE-style sensor fitment

Installation Notes and Tips

Verify the vehicle year, make, model, and engine application against the catalog fitment before ordering. Some listings note installation at the air cleaner pipe, so confirm the mounting location on the vehicle before replacement. Use the part number MP158 and the vehicle-specific fitment data to confirm the correct sensor for the application.

Quality Assurance

Spectra states that this sensor is designed to meet or exceed OE specifications for fit, form, and function.
