大众朗逸08-12款/新宝来新捷达曲轴传感器 HOP 03C906433B 耐用可靠

When your vehicle has starting difficulty, idle instability, acceleration weakness or sudden stalling, this is likely due to aging or damaged crankshaft position sensor, causing the engine control unit to fail to obtain accurate crank speed and position signals. When functioning properly, this sensor monitors crank angle and engine RPM in real time to provide critical data for ignition timing and fuel injection control, ensuring smooth engine operation. This product fits VW Lavida 08-12, New Bora, and New Jetta models, OEM number 03C906433B. During installation, ensure proper gap between the sensor and tone wheel (usually 0.5–1.5 mm) and fasten bolts to the standard torque to avoid signal interference or looseness.
