大众途安1.6L 氧传感器 04E906262DH 原厂标准替换件

If your vehicle experiences rough idle, sluggish acceleration, noticeably higher fuel consumption, or the engine warning light is on, this is typically due to aging or failure of the oxygen sensor. This sensor monitors oxygen content in the exhaust in real time and feeds back to the ECU to precisely control the air-fuel ratio, ensuring efficient combustion and compliant emissions. This product is an original-standard replacement part, OEM number 04E906262DH, for VW Touran 1.6L models. When installing, be sure to use a dedicated socket to avoid damaging threads, and ensure the sensor harness does not contact the exhaust pipe to prevent heat damage.
