Crankshaft Position Sensor – 6429050000 | Mercedes Sprinter Engine Crank Sensor

SKU: 6429050000 - qty 1

Ensure precise engine timing, performance, and start-up reliability with this Crankshaft Position Sensor – part #6429050000 for your Mercedes Sprinter. The crankshaft position sensor (CKP) monitors the position and rotational speed of the crankshaft and sends that critical data to your vehicle’s Engine Control Unit (ECU). The ECU uses this information to properly time fuel injection, combustion events, and, in diesel engines, injector timing and pump control — making it essential for smooth running and efficient operation. 

A failing or intermittent crankshaft position sensor can lead to symptoms such as no-start conditions, engine stalling, hard starting, rough idle, misfires, or illumination of engine warning lights. Replacing it with a direct-fit sensor helps restore accurate engine timing signals and dependable engine performance. 

✔ OEM-Equivalent Crankshaft Position Sensor

• Designed according to Mercedes-Benz part 6429050000 / A6429050000 for correct fit and precise signal feedback. 

• Installs at the crankshaft/flywheel end of the crankshaft to reliably detect rotation position and speed. 

✔ Improves Engine Control & Diagnostics

• Helps the ECU determine engine load and speed, optimizing fuel timing, injection control, and emissions. 

• Critical for starting, idle stability, acceleration response, and engine diagnostics. 

✔ Durable & Direct Fit

• Engineered to withstand engine bay heat, vibration, and harsh conditions for long-lasting performance.

• Plug-and-play design means straightforward installation with the existing wiring harness.

📌 Fitment Tip: Always verify fitment with your Sprinter’s VIN, year, and engine code to ensure this sensor matches your specific application — especially when diagnosing timing or misfire-related fault codes.
