道奇氮氧传感器 68352149AB 0281007477 68404997AA 精准排放监测

Your Dodge may show check engine light on, weak acceleration, or high fuel consumption? This often indicates nitrogen oxide sensor aging/failure; it no longer accurately monitors NOx in exhaust. When functioning correctly, this sensor feeds NOx data to ECU to optimize air-fuel ratio for efficient operation and emissions compliance. OEM numbers: 68404997AA, 68352149AB, 0281007477; compatible with many Dodge models. Installation ensures sensor harness secure, avoid bending or contact with high-temperature exhaust; after installation, erase codes with diagnostic tool and relearn.
