Bosch 0261210147 Crankshaft Position Sensor

The Bosch 0261210147 Crankshaft Position Sensor is a precision-engineered component that monitors the position and rotational speed of the crankshaft, providing critical data to the Engine Control Unit (ECU) for optimal engine performance. This sensor plays an essential role in controlling ignition timing and fuel injection, ensuring smooth and efficient engine operation.

Key Features:

• Inductive sensor technology with permanent magnet and soft-iron core for reliable operation
• 900 Ohm resistance for precise signal transmission
• 570mm (22.4 inch) cable length for flexible installation
• 3-pole terminal connector for secure electrical connection
• 24mm fitting depth designed for proper positioning
• OE-quality construction matches or improves upon original equipment design

Technical Operation:

This sensor uses inductive technology to detect crankshaft rotation. A gear rim fitted to the flywheel serves as the pulse transmitter, with a small air gap between the sensor and the gear teeth. As the flywheel rotates, each gear tooth creates changes in the magnetic field, generating induction voltage that the ECU interprets as engine speed and position data.
