NOTE: THE TIP OF THE NEW OXYGEN SENSOR MAY BE SLIGHTLY DISCOLORED
DUE TO FINAL HEAT TESTING.

  1. Disconnect the oxygen sensor electrical connector.
  2. Remove the oxygen sensor from the vehicle.

    CAUTION: The oxygen sensor is located in the exhaust system which reaches high temperatures that could result in burns or injury. Take proper precautions when removing sensor to prevent injury.

  3. Cut the original positive wire so that the total length when spliced is the same or slightly longer than the original oxygen sensor wire.

  4. Strip 3mm of insulation from the end of the cut wire.
  5. Slip a piece of the heat shrink tube over the wire.
  6. Crimp the terminal to both wires.
    NOTE: It is recommended to solder the terminal using rosin core solder.
  7. Slide the heat shrink tube over the terminal. Heat the tube with a heat gun, match, or lighter, until it shrinks and weather seals the terminals.

  8. The new oxygen sensor may have a rubber or plastic cap over the threaded area. Remove this cap before installing the oxygen sensor.
    NOTE: The threads of the oxygen sensor are coated with a special anti-seize compound that allows for easy removal. Do not remove this coating. Also take care not to get any of this anti-seize on the sensor's tip or damage to the sensor may occur.
  9. Install the new oxygen sensor into its location and tighten to the proper torque listed in the service manual for your vehicle.
  10. Reconnect the sensor's electrical connector.
  11. Following the procedures outlined in the service manual for your vehicle, clear any codes that may have been set.
