奔驰吉普道奇克莱斯勒氧传感器0258017118 0258017018 空燃比

When your Mercedes-Benz, Jeep, Dodge or Chrysler vehicle shows check engine light, rough idling, sluggish acceleration, or abnormal fuel consumption, this often means the oxygen sensor (air–fuel ratio sensor) is aging or failed and cannot accurately monitor oxygen in the exhaust.

When functioning normally, this part continuously detects oxygen concentration in the exhaust and feeds the signal back to the ECU to precisely control fuel injection, ensuring the engine runs at the optimal air–fuel ratio, thereby enhancing power, reducing emissions, and saving fuel.

Compatible OEM numbers include: 0258017018, 0258017019, 0035427118, 0258017016, suitable for multiple Mercedes-Benz, Jeep, Dodge and Chrysler models.

Installation notes: always operate after the engine has cooled; avoid burns; when removing the old sensor, use a dedicated socket to prevent thread damage; before installing the new sensor, apply a small amount of anti-seize on the threads and tighten to the standard torque, to avoid housing deformation from over-tightening.
