The BLUE PRINT ADG072100 Crankshaft Pulses 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 data is fundamental for precise ignition timing and fuel injection, directly impacting the engine's overall performance, fuel economy, and emissions. A malfunctioning sensor can lead to rough idling, stalling, poor acceleration, and the illumination of the check engine light. Manufactured to meet stringent quality standards, this sensor offers reliable and consistent performance. Its direct fit design ensures straightforward installation, replacing your original equipment with confidence.
