别克凯越1.6/HRV乐风1.4曲轴位置传感器0261210285，发动机运转信号精准

If your vehicle experiences starting difficulty, weak acceleration, intermittent engine stalling, or engine check light on, these are typical signs of crankshaft position sensor aging or failure. When functioning, this sensor precisely monitors crankshaft speed and position and transmits signals to the ECU in real time to ensure ignition timing and fuel injection timing are accurate, maintaining smooth engine operation. This sensor OEM code is Yuexiang 475 (compatible with 0261210297); compatible with Buick Excelle 1.6, HR-V, and Lifan 1.4 models. Installation: ensure power is cut, clean mounting holes, verify 0.5–1.5 mm clearance between sensor and flywheel ring gear, tighten bolts to 8–12 N·m to avoid signal interference.
