5-14 Service and Maintenance
Replacing the Oxygen
Sensor Clips
The oxygen sensor is connected to the electronics via two contact
clips located at the base of the sensor. The
upper clip is electrically
isolated from the lower clip by a non-conductive band on the sensor
body. Both clips simply snap around the body of the sensor.
The following tools are needed to replace the oxygen sensor clips:
•
pliers
•
wire cutters
•
wire strippers
•
crimping tool
Power may remain on while completing the following steps:
1.
Open the sensor enclosure cover.
2.
Locate the oxygen sensor and the oxygen sensor clips (see
Figure 5-2 on page 5-25).
Note:
For information regarding component locations and/or wiring
connections in an optional enclosure, see Appendix C.
IMPORTANT:
Never touch the coating on the oxygen sensor with
bare hands.
3.
Use pliers to remove the upper and lower clips from the oxygen
sensor. The clips are easily removed by pulling them away from
the oxygen sensor body.
4.
Cut off the old upper clip, leaving the remaining wire as long as
possible.
5.
Strip 1/2” of insulation off the upper clip wire, and slide the new
upper clip over the stripped wire. Using a crimping tool, crimp the
new upper clip onto the upper clip wire.
6.
Repeat steps 4 and 5 to install the new lower clip.
7.
Reinstall both clips onto the oxygen sensor body.
8.
Close the cover on the sensor enclosure.
9.
Recalibrate the oxygen sensor as described in “Calibrating the
Model CGA 351” on page 4-31.
This completes the replacement of the oxygen sensor clips.
