Oxygen (O2) Sensor: Installation

  1. Whenever an oxygen sensor is removed, threads must be coated with anti-seize compound before it is reinstalled. New oxygen sensors will already have this compound applied to threads.
  2. Install oxygen sensor in exhaust pipe and tighten sensor to 30 ft. lbs. (41 N.m). Reconnect electrical connector to oxygen sensor. Reconnect negative battery cable.
