一汽森雅后氧传感器 89465-BZ160 直接更换无需编程

This downstream oxygen sensor is designed for FAW Senia S80 (2011-2015, 1.3L/1.5L) and Senya M80 (2010-2014, 1.3L/1.5L), directly replacing the original part with no ECU programming or reflashing required. Its core function is to monitor oxygen content in the exhaust and feed back to the engine computer to optimize the air-fuel ratio, ensuring efficient operation of the catalytic converter and reduced emissions. OEM number 89465-BZ160. Buyers should verify the vehicle’s part number before shipping to avoid misfit. Replacement difficulty is medium; use a dedicated oxygen sensor socket and apply anti-seize compound to prevent thread seizing. For B2B buyers, this sensor is a generic four-wire design compatible with most Japanese vehicles and can be stocked in bulk to cover multiple models.
