Detailed Description

The Delphi SS11178 crankshaft position sensor monitors crankshaft rotation and sends the signal the engine control system uses to manage ignition timing and fuel delivery. When the signal becomes weak or inconsistent, drivability problems can follow. This sensor is listed for a wide range of Mercedes-Benz vehicles, including C63 AMG, E350, ML350, S550, and Sprinter 2500 applications. This part cross-references Standard Ignition PC738 and Spectra Premium S10220 for the same application.

Use Delphi SS11178 when you need a Mercedes-Benz crankshaft position sensor replacement that matches the original connector style and terminal layout. It is also a relevant search match for Mercedes-Benz crankshaft position sensor replacement, Mercedes-Benz engine speed sensor, and Delphi SS11178 fitment across 2005-2015 model years.

What It Helps Solve

• Hard starting caused by an unreliable crankshaft signal
• Intermittent stalling or sudden engine shutdown
• Misfire or rough-running conditions tied to timing input errors
• Check engine light concerns related to crankshaft position sensor faults
• Crank signal loss that affects ignition and fuel control

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle fitment before installation. This sensor uses a female oval connector with 3 terminals and does not include a wiring harness. On listed Mercedes-Benz applications, confirm the exact model year and any notes shown in the fitment data, including the 2011 E350 note and the 2010-2011 ML450 note that all parts must be replaced together.

For search relevance, this part is commonly referenced for Fits 2006-2011 Mercedes-Benz E350, Fits 2007-2011 Mercedes-Benz ML350, and Fits 2008-2015 Mercedes-Benz C63 AMG applications.

Quality Assurance

Delphi draws on OE engineering experience and supplier knowledge developed through work with major automakers. That background is reflected in the design and application coverage of the SS11178 crankshaft position sensor.
