吉利/小康/民意欧三德尔福系统曲轴传感器 德尔福 28129701 原厂品质

Delphis/Geely/Chery EURO III emission standard crankshaft sensor (Delphi brand, OEM 28129701) directly replaces original defective part to restore crankshaft position and speed monitoring. Sensor sends signal to ECU to control ignition timing and injection timing; ensures engine normal operation. Replacement resolves startup difficulty, acceleration weakness, or rough idle, especially for older vehicles to restore power. If misfire, sudden stalling, or engine warning lamp stays on, sensor aging is likely; replace promptly to avoid bigger faults.
