Bosch 270-905-04-00 Camshaft Position Sensor

The Bosch 270-905-04-00 is a precision-engineered camshaft position sensor designed to monitor the exact position and rotational speed of the camshaft in your engine. This sensor enables the engine control unit to determine the exact position of the camshaft, providing critical information required to calculate ignition timing and fuel injection timing. As an OEM-quality component from Bosch, this sensor ensures reliable performance and precise compatibility with your vehicle's engine management system.

Key Features:

• Hall-effect sensor technology that scans a ring gear on the camshaft, with voltage changes transmitted to the control unit for evaluation
• Bosch part number 0 232 103 125, cross-references to Mercedes-Benz OEM numbers A2709050400 and 2709050400
• True power-on function provides immediate camshaft position information upon starting, enabling exact injection and ignition timing
• High-precision electronic component for accurate engine synchronization
• Direct OEM replacement for proper fit and function

The camshaft position sensor monitors and reports the exact position and rotational speed of the camshaft to the engine control module (ECM), which regulates various aspects of engine operation. As the camshaft rotates, the sensor records its position, helping the ECU synchronize the opening and closing of intake and exhaust valves with the corresponding piston position. This ensures optimal engine performance, fuel efficiency, and emissions control.
