标致雪铁龙节气门位置传感器 9643365680 精准控制进气

This throttle position sensor is designed for Citroën C4, C5, C4/5, Saxo, and similar models (2010-2018, 1.6L/2.0L), accurately monitoring throttle opening and feeding back to the ECU to ensure proper intake and fuel injection. OEM number 9643365680 (also compatible with 1607272480) for cross-checking stock. Replacement difficulty: medium; requires removing the intake pipe and throttle body. Use a torque wrench to install at standard torque to avoid seal leaks. This sensor is a wear part; bulk stocking covers multiple Citroën best-selling models to reduce after-sales response time.
