Product Information
Speed sensor plays a vital role in your vehicle’s engine management system. It continuously monitors the crankshaft’s speed and position, sending accurate signals to the ECU. Without this data, the engine cannot control ignition timing or fuel injection correctly, leading to poor performance or even a complete no-start condition.
