HOP 曲轴位置传感器 10456506 别克凯越1.8/景程1.8/大宇 原装替换件

If your Buick Excelle (LaCiva) 1.8 or Guangqing 1.8 experiences starting difficulty, rough idle, sluggish acceleration, or engine fault light on, the crankshaft position sensor may be aging or damaged. This sensor normally monitors crankshaft speed and position and transmits the signal to the ECU to control ignition timing and injection, ensuring smooth engine operation. This is an OEM replacement with number 10456506, compatible with Buick Excelle 1.8, Epica 1.8, and other Daewoo-displacement models. During installation, ensure proper clearance between the sensor and crank signal gear, and tighten to standard torque to avoid signal interference.
