Product Details

The Delphi SS12020 is an engine crankshaft position sensor designed to read crankshaft position and rotational speed so the engine control system can manage timing and fuel delivery accurately. Delphi draws on more than a century of OE experience, and that background is reflected in the fit, form, and signal quality expected from an aftermarket replacement. This part cross-references Standard Ignition PC1003 for the same application.

Compatible With Mercedes-Benz models including C43 AMG, G550, GLC43 AMG, GLE580, GLS580, Maybach S580, S580, SL63 AMG, G63 AMG, Sprinter 2500, Sprinter 3500, AMG GT, C63 AMG, E63 AMG S, GLC63 AMG, GLS63 AMG, S63 AMG, and other listed applications. The Delphi SS12020 is also a direct-fit option for many Mercedes-Benz engines across 2010-2023 model years, including several optional-fit applications noted in the fitment data.

What It Helps Address

• Crankshaft signal loss or intermittent engine speed readings
• Hard starting or extended crank conditions
• Check engine lights related to crankshaft position sensor faults
• Rough running caused by inaccurate timing input
• Stalling or hesitation tied to poor engine position data

Installation Notes

Verify connector shape, terminal count, and vehicle fitment before installation. This sensor uses a female oval connector with three terminals and does not include a wiring harness. Follow the included instruction sheet and inspect the connector and mounting area for corrosion, oil contamination, or damaged wiring before completing the repair.

Quality Assurance

Delphi builds aftermarket parts using OE knowledge and supplier experience developed over decades of original-equipment production. The SS12020 reflects that OE-focused approach for Mercedes-Benz crankshaft position sensor replacement.
