日产前后氧传感器套装 234-8060/234-9303 22693-5RB0A 上下2件装

When your Nissan vehicle shows check engine light, abnormal fuel consumption, rough idle, or accelerated power loss, it usually indicates aging or failure of the upstream and downstream oxygen sensors, which cannot accurately monitor oxygen content in the exhaust. In normal operation, the oxygen sensors provide real-time feedback to the ECU to maintain optimal combustion efficiency, reducing emissions and improving power. This kit includes two sensors, OEM numbers 22693-5RB0A (corresponding to 234-8060/234-9303), compatible with multiple Nissan models. Installation requires a dedicated socket to avoid sensor thread damage, and note that the front and rear sensors are not interchangeable. After installation, clear fault codes and let the vehicle reach operating temperature to complete adaptive learning.
