日产颐达骊威轩逸前后氧传感器 226A0-ET000，燃油效率优化之选

KLP oxygen sensor (OEM: 226A0-ET000, compatible 22693-CJ00A) directly replaces the factory part with wide compatibility. Core function: real-time monitoring of exhaust oxygen and sending signal to ECU to control fuel injection for optimum air–fuel ratio. Fits Nissan Versa Note, Latio, Sylphy and other models; post-installation, significant improvements in fuel economy and throttle response can be observed. If idle is unstable, exhaust emits black smoke, or the check engine light illuminates, the oxygen sensor is aging and should be replaced promptly.
