The MEAT & DORIA 87074 Crankshaft Position Sensor is a critical component for modern engine management systems. It accurately monitors the rotational speed and position of the crankshaft, providing vital data to the engine control unit (ECU). This sensor's input is fundamental for the ECU to precisely control ignition timing and fuel injection. Without a functioning crankshaft position sensor, the engine may experience issues such as rough idling, stalling, misfires, or failure to start altogether. Crafted with quality materials, the 87074 sensor is designed for durability and reliable operation under demanding engine conditions. Its precise manufacturing ensures it integrates seamlessly with your vehicle's existing system, restoring or maintaining optimal engine function.
