日产英菲尼迪节气门位置传感器 SERA483-1 — 替换22620-53J01，加速响应灵敏

Are you experiencing acceleration delay, rough idle, or engine fault light on? These symptoms typically indicate a worn throttle position sensor (TPS) causing ECU to misread throttle opening. When functioning normally, this sensor monitors throttle angle in real time and transmits signals to ensure responsive acceleration and smooth shifting. This product with OEM number SERA483-1 can replace 22620-53J01 and fits many Nissan and Infiniti models (e.g., Q50, Q70, G37). During installation, first disconnect the negative battery, ensure the sensor mounting surface is clean and free of oil, and tighten bolts to OEM torque.
