名爵MG GS 荣威950 氧传感器 0258017506 前氧传感替换

If your vehicle shows engine check light, rough idle, weak acceleration, or abnormal fuel consumption, this is typically a symptom of aging or failure of the front oxygen sensor. It monitors exhaust oxygen and feeds ECU to precisely control air-fuel ratio for efficient combustion and reduced emissions. Applicable models include MG GS and Roewe 950; OEM 0258017506/10128840; direct replacement for factory front oxygen sensor. Installation must be performed with a cold engine; disconnect battery negative before removal; pay attention to sensor harness routing to prevent twist or compression.
