The DELPHI SS11173 Crankshaft Position Sensor is a critical component for modern engine management systems. It accurately detects the rotational speed and position of the crankshaft, providing vital data to the engine control unit (ECU). This information is essential for precisely controlling ignition timing and fuel injection, which directly impacts engine performance, fuel efficiency, and emissions. A malfunctioning sensor can lead to various drivability issues, including rough idling, stalling, and difficulty starting. Designed as a direct replacement, the SS11173 offers a reliable solution to restore or maintain optimal engine operation. Its robust construction ensures durability and consistent performance under demanding automotive conditions.
