Buick Excelle (LaCrosse) 1.6L and Lifan 1.4L owners: HOP camshaft position sensor (OEM 96253544) uses a high-temperature engineered plastic housing and sealing ring to resist oil contamination and vibration; tested for durability on dynos, signal is stable with replacement. This sensor monitors camshaft position and provides ignition and injection timing signals to the ECU to ensure stable idle and smooth acceleration.
