  Q: How Should I Be Particularly Careful When Servicing an Oxygen Sensor?

  A: Oxygen sensors are delicate, so handle them carefully. For the 2.4L engine (2014 and earlier), the upstream sensor is near the exhaust manifold, while on all other engines, the left and right upstream sensors are at the top of the Catalytic Converters. The downstream sensors are on the side of each catalytic converter. To remove the sensor, disconnect the wire harness and connector, and unscrew the sensor using a special oxygen sensor socket. Clean the threads of the sensor bore if reusing the old sensor, and apply anti-seize compound to the threads if necessary. Install the sensor and tighten it to the specified torque.
