三菱欧蓝德劲界 氧传感器 1588A081 23400-4738 稳定输出

Mitsubishi Outlander/Montero 2010–2015 2.0L and 2.4L models; cross-compatible with original number 23400-4738 and compatible with 1588A081 oxygen sensor. General replacement part; plug-and-play. Core function: monitor exhaust oxygen content and transmit signal to ECU to precisely control fuel injection, improving combustion efficiency. Replacement resolves common issues like high fuel consumption, rough idle, and weak acceleration. If engine warning light comes on or exhaust emits black smoke or fuel consumption spikes, sensor failure is likely; replace promptly.
