Chevrolet Aveo Front Oxygen Sensor 96418965 OEM Quality Replacement

When a Chevrolet Aveo shows rough idle, weak acceleration, high fuel consumption, or check engine light, it is usually the front oxygen sensor aging or failure. This sensor monitors exhaust oxygen content and sends data to the ECU to adjust the air-fuel ratio; OEM numbers include 96418965, 96415639, 96325533, 96291099; fits Aveo series. Before installation, disconnect the negative battery; ensure sensor threads are clean; use a dedicated socket and avoid over-tightening to protect the ceramic element.
