It sends the information information technology collects to the Electronic Control Unit (ECU) which is the main computer onboard your Mercedes.

The information given by the crankshaft position sensor allows the ECU to make alterations every bit needed to ensure your Mercedes achieves loftier-level functioning. This means that authentic data regarding the crankshaft position and speed is essential for maintaining good engine management and timing. Ultimately, when the crankshaft position sensor fails, the engine is unable to run correctly if at all.

As a declining crankshaft position sensor throws the engine's timing into dysregulation, it can cause the ECU to trigger the engine management light.
