Fitting Universal Sensors - Single Wire.
|
NOTE: THE TIP OF THE NEW OXYGEN SENSOR MAY BE
SLIGHTLY DISCOLORED
DUE TO FINAL HEAT TESTING.
|
- Disconnect the oxygen sensor electrical connector.
- 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.
- Cut the original positive wire so that the total length when spliced is the same or slightly longer than the original oxygen sensor wire.
- Strip 3mm of insulation from the end of the cut wire.
- Slip a piece of the heat shrink tube over the wire.
- Crimp the terminal to both wires.
NOTE: It is recommended to solder the terminal using rosin core solder.
- 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.
- 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.
- Install the new oxygen sensor into its location and tighten to the proper torque listed in the service manual for your vehicle.
- Reconnect the sensor's electrical connector.
- Following the procedures outlined in the service manual for your vehicle, clear any codes that may have been set.
