Bosch 996-606-105-02 Crankshaft Position Sensor

The Bosch 996-606-105-02 Crankshaft Position Sensor is an OEM-quality engine management component that monitors the position and rotational speed of the crankshaft. Also known as a reference mark sensor or crankshaft pulse sender, this critical sensor provides accurate data to the Engine Control Unit (ECU) to control ignition timing and fuel injection for optimal engine performance.

Key Features:

• Genuine Bosch OEM quality sensor with robust design for improved temperature shock stability
• Inductive sensor technology provides precise measurement of crankshaft rotational speed and position
• Enlarged temperature range and reduced drift during lifetime for long-term reliability
• Critical component for modern engine management systems
• Helps improve engine performance, increase fuel efficiency, and reduce emissions

The crankshaft position sensor is mounted near the crankshaft and uses non-contact scanning to monitor engine speed, which is the main control variable for ignition timing. This sensor also monitors valve timing and piston RPM. A faulty crankshaft position sensor is a common cause of no-start conditions, and symptoms may include intermittent starting issues, particularly when the engine is warm.
