Delphi SS12318 Engine Crankshaft Position Sensor

Engine Crankshaft Position Sensor for Mercedes-Benz

Restore accurate engine speed and crankshaft timing signal output with the Delphi SS12318 engine crankshaft position sensor. This OE-calibrated sensor is built for Mercedes-Benz applications and uses a black housing with a single oval male connector for a direct-style replacement.

Compatible with select Mercedes-Benz C300, CLA250, GLA250, GLC300, E350, Sprinter 2500, and related models, the Delphi SS12318 is a practical choice when diagnosing crank signal faults or intermittent drivability concerns. Delphi validates its sensors to OE standards to help deliver consistent readings and reduce repeat repairs.

Key Features

• Engine crankshaft position sensor for ignition and engine management systems
• OE-standard testing and calibration for accurate signal output
• Black sensor body with 1 oval connector and 3 terminals
• Male connector and male terminal design
• Single mounting hole layout for application-specific installation
• Package contents include the engine crankshaft position sensor and instruction sheet

Detailed Description

Delphi SS12318 is an engine crankshaft position sensor engineered for Mercedes-Benz vehicles that rely on precise crankshaft position data for ignition timing and engine control. It cross-references Standard Ignition PC1057 and is used in applications such as Mercedes-Benz C300, CLA250, GLA250, GLC300, E350, and Sprinter 2500. Delphi’s sensor portfolio is developed and validated to OE standards, supporting accurate readings across a wide range of vehicle sensor applications.

This part cross-references Standard Ignition PC1057 for the same application.

What It Helps Address

• Crankshaft position sensor fault codes
• Intermittent no-start or hard-start conditions
• Rough idle caused by incorrect crank signal input
• Engine stalling related to crankshaft timing signal loss
• Misfire or drivability issues tied to sensor signal errors

Installation Notes and Tips

• Verify connector shape, terminal count, and mounting style before installation.
• Inspect the harness and connector for corrosion, bent terminals, or damaged wiring.
• Clear diagnostic trouble codes after installation and confirm proper engine operation.
• Use the vehicle’s service information to confirm the exact application by year and model.

Quality Assurance

Delphi sensors are tested and calibrated to OE standards and validated through stringent development methods. That focus on signal accuracy helps support reliable engine management performance in Mercedes-Benz applications such as C300, CLA250, and GLC300.
