大众新速腾氧传感器 04E906262CM 即插即用原厂替代件

For the latest VW New Jetta (2012-2018) and MQB platform models, OEM replacement oxygen sensor 04E906262CM installed upstream and downstream of the catalytic converter. Core function is real-time monitoring of exhaust oxygen and feeding ECU to precisely control the air–fuel ratio to meet combustion and emission standards. Installation difficulty medium; expect about 0.5–1 hour of labor. Avoid damaging threads and wiring harness. If idle is unstable, fuel consumption surges, acceleration is weak, or the check engine light is on, sensor aging or failure is usually indicated.
