现代起亚曲轴位置传感器39180-25300 引擎转速感应器精准匹配

Your vehicle may have starting difficulties, weak acceleration, rough idle, or stalling due to aging or damage to the crankshaft position sensor, causing ECU to fail to obtain accurate engine speed data. This sensor monitors crank angle and speed to provide critical data for ignition timing and fuel control, ensuring smooth engine operation. OEM number 39180-25300; precisely matches many Hyundai-Kia models (e.g., Sonata, Elantra, K5). Install with clean mounting hole; ensure correct clearance between sensor and flywheel gear; tighten bolts to standard torque to avoid signal interference.
