Bosch 06A-905-161 B Camshaft Position Sensor

The Bosch 06A-905-161 B is a precision-engineered camshaft position sensor designed to monitor the exact position and rotational speed of the camshaft in your engine. This critical sensor works with the engine control module (ECM) to optimize ignition timing, fuel injection timing, and valve operation for peak engine performance.

Key Features:

• OE-quality Hall Effect sensor technology for accurate camshaft position detection
• High accuracy and long service life for reliable engine management
• Monitors camshaft rotation to ensure proper valve timing and combustion cycles
• Enables ECM to control spark timing and fuel injector operation
• Also known as Hall sensor, G40 sensor, or reference mark position sensor

This genuine Bosch sensor provides the ECM with real-time data about camshaft position, allowing the engine control system to synchronize fuel delivery, ignition timing, and valve operation. Without a properly functioning camshaft position sensor, engines may experience hard starting, rough idling, stalling, or reduced performance. Bosch OE-equivalent part number 0-232-101-031 cross-references to VW/Audi part number 06A-905-161-B.
