丰田卡罗拉/威驰变速箱速度传感器89413-50020，原厂标准信号输出

The Toyota Corolla, Vios, and other models use a transmission speed sensor (OEM 89413-50020/89413-02010) produced by KLP, monitors output shaft speed in real time and transmits signals to the ECU to ensure accurate shifting logic. If the vehicle experiences shift shudder, weak acceleration, or the fault light on, replacing this sensor restores smooth shifting and prevents transmission lockup or excessive wear. Original-spec signal output; direct replacement of the original part.
