别克GL8脉冲式曲轴位置传感器 10456568 HOP稳定输出，恢复动力

Buick GL8 pulse crankshaft position sensor, wired to HOP 10456568, directly replaces original 10456568. High universality; mounts ready-to-use on old LUXren (Lexus?) and new GL8 models. Core function is precise crankshaft position monitoring, sending signal to ECU to ensure ignition and injection timing accuracy. Effectively resolves starting difficulties, rough idle, and weak acceleration to restore power output. If occasional stalling, repeated starting required, or engine warning lights illuminate, sensor aging is likely; replace early to avoid breakdown.
