Detailed Description

Spectra MP177 is a manifold absolute pressure sensor designed for Mercedes-Benz vehicles that rely on precise manifold pressure data for fuel delivery, load calculation, and drivability control. The sensor’s OE-style construction supports proper electrical connection and physical fit in applications such as Mercedes-Benz CLA250, GLC43 AMG, S560, and Sprinter 2500. If you are replacing a failing MAP sensor on a Mercedes-Benz A35 AMG, AMG GT 53, or E53 AMG, MP177 provides a direct-match service part for the listed fitments.

This part cross-references Standard Ignition AS490 for the same application.

What It Helps Address

• Check engine light related to manifold pressure signal faults
• Rough idle or unstable engine operation caused by incorrect pressure readings
• Reduced throttle response from inaccurate load calculation
• Fuel trim issues tied to faulty intake manifold pressure input
• Drivability concerns on turbocharged and performance Mercedes-Benz models

Installation Notes and Tips

Verify connector shape, terminal count, and port configuration before installation. Confirm the vehicle application against the fitment list, since MP177 is used across multiple Mercedes-Benz platforms and model years. Inspect the air cleaner pipe or intake connection point for damage, contamination, or loose fittings before installing the new sensor. Clear diagnostic trouble codes and recheck live data after replacement to confirm proper sensor operation.

Quality Assurance

Spectra states that this manifold absolute pressure sensor is manufactured to meet or exceed OE specifications for fit, form, and function. Part number MP177 is built as an OE-style replacement for the listed Mercedes-Benz applications.
