URO Camshaft Position Sensor - BMW E36 Z3 M42 M44

The URO Camshaft Position Sensor - BMW E36 Z3 M42 M44 is an essential component for precise engine timing and efficient performance. Also known as the pulse generator, this sensor mounts to the side of the cylinder head and detects the camshaft’s position to optimize fuel injection and ignition timing. A failing sensor can trigger engine fault codes, cause rough idling, misfires, or poor fuel economy. Replacing a faulty camshaft position sensor restores accurate timing, ensuring smooth operation and peak efficiency for your BMW E36, Z3, M42, or M44 engine.
