Nissan Tiida Livina Sylphy Front and Rear Oxygen Sensor 226A0-ET000, Fuel Efficiency Optimization Choice

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.
