长城赛弗/奇瑞联电无胶圈专用HOP曲轴位置传感器0261210127

This HOP crankshaft position sensor 0261210127 directly replaces OEM 0261210127, designed for Great Wall Cevrier and Chery Liantong systems; note this version does not include an O-ring, broad compatibility. Its core function is to monitor crankshaft speed and position and send signals to the ECU to control ignition and fuel injection, ensuring normal engine operation. Fits Great Wall Cevrier and Chery Liantong systems; after installation, it can resolve starting difficulties, unstable idle, or weak acceleration. If the car occasionally fails to start, engine vibrates noticeably, or the check engine light is on, this is likely sensor aging—replace with this.
