This crankshaft position sensor, also known as an impulse sender, is a critical component for your vehicle's engine management system. It accurately measures the rotational speed and position of the crankshaft, providing essential data to the engine control unit (ECU). This information is vital for precise ignition timing, fuel injection control, and overall engine performance. Manufactured by CONTINENTAL/VDO, this part ensures reliable operation and helps maintain your engine's efficiency and responsiveness. Replace a faulty sensor to prevent issues like stalling, rough idling, or starting problems.
