The MEAT & DORIA Crankshaft Position Sensor (Part Code: 87668) is a critical component for modern engine management systems. It accurately detects the rotational speed and position of the crankshaft, sending this vital information to the engine control unit (ECU). This data is fundamental for the ECU to calculate and control ignition timing and fuel injection. A properly functioning sensor ensures smooth engine operation, prevents stalling, and contributes to better fuel economy. It is designed to meet or exceed original equipment specifications for reliable performance. Installation of this sensor is crucial for maintaining the health and efficiency of your vehicle's powertrain. Symptoms of a failing sensor can include intermittent starting issues, rough idling, poor acceleration, and the illumination of the check engine light.
