Oxygen sensor on the exhaust pipe (OEM: 1K0998262T), also known as the air-fuel ratio sensor, is the core component for precise control of fuel injection. It monitors exhaust oxygen content in real time and feeds signals to the ECU to ensure combustion efficiency and emissions compliance. This sensor is compatible with 0258006986, 0258010038, 06J906262N and broadly fits models such as Magotan (Passat), etc. Installation requires a dedicated socket. Labor time is 30-45 minutes. Protect threads during installation. Aging often causes increased fuel consumption and sluggish acceleration; timely replacement can restore engine performance.
