The TOPRAN 502 682 Crankshaft Position Sensor 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 precisely control ignition timing and fuel injection. Without a functioning crankshaft position sensor, the engine may experience issues such as rough idling, stalling, difficulty starting, or a complete failure to run. Crafted with quality materials, this TOPRAN sensor is designed for reliable and long-lasting performance, helping to maintain your vehicle's optimal operational state and fuel economy.
