Fold the split portion of the jacket back and use small shears to trim the jacket at the
mark to the outside diameter of the lead wire stalk.
12.
Strip the outer insulation to expose two insulated wires, one red and one yellow.
Carefully inspect each wire for nicks or cuts. If nicks or cuts are found, either cut out
the nicked portion of wire and splice the wire or trim the lead wire to remove the
damaged section.
13.
After confirming the entire lead wire is intact and continuous, free of nicks or cuts,
smooth the cut edge of the wire by carefully rolling it between your thumb and index
finger until the wire edge appears as shown in Figure 10-13.

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
