The MEAT & DORIA 87245 Crankshaft Position Sensor is a critical component for modern engine management systems. It accurately monitors the rotational speed and position of the crankshaft, transmitting this vital data to the engine control unit (ECU). This precise information allows the ECU to determine the correct ignition timing and fuel injection sequence, which are fundamental for smooth engine operation, power delivery, and fuel economy. A malfunctioning sensor can lead to various drivability issues, including rough idling, stalling, misfires, and the check engine light illuminating. Crafted with quality materials, the 87245 sensor is designed to meet or exceed original equipment specifications, ensuring reliable and long-lasting performance. Its direct-fit design simplifies installation, making it a straightforward replacement for a faulty unit.
