A crank angle sensor monitors the rotation angle of the crankshaft, providing critical data to the ECU for precise fuel injection and ignition timing. This sensor determines piston position (e.g., top dead center during compression), enabling optimal engine performance. For Japanese, American, German, French, and Chinese vehicles, our crank angle sensors ensure reliable operation in engine start-up, speed control, and fault diagnosis.
