Smooth Braided Shield
11.
With the shield prepared, untwist and straighten the two sensor leads until the wires
are parallel. One wire has a colored stripe, called the “trace wire.”
Figure 10-40.
Identify Wires within Harness
12.
Cut the white wire on one segment of the repair one inch shorter than the trace wire.
13.
Strip the sensor wires 1/2-inch from their cut ends. The prepared wire should
resemble Figure 10-41.

Properly Prepared Non-EGT Sensor Lead Wire
14.
Repeat steps 5 through 13 for the mating end of the lead or sensor wires except in
Step 12, cut the trace wire one inch shorter than the white wire.
15.
Consult the engine low voltage harness wiring diagrams in Chapter 8. Check the
continuity of the wires under repair before installing a splice or new sensor. If the
resistance is greater than 500 ohms, closer inspection of the harness segments may
reveal additional damage. If there is no continuity between the referenced pins, verify
connector pin references are correct and repeat the measurement. Repairing a single
segment if the circuit remains open will not resolve a wiring malfunction.
CAUTION: If the shield splice is not placed over the wires before
Step 18, the splice repair cannot be correctly completed without
removing the solder sleeves.
