Inspect the continuity of the sensor lead wires. If the inspection reveals poor
continuity readings and/or if any wire appears damaged, isolate the faulty wiring and
repeat the procedure.
33.
If splice was for wire repair, proceed to step 34. If sensor was removed for
replacement, install the EGT sensor according to instructions in Section 10-6.20
“Exhaust Gas Temperature Sensor Installation.”
34.
If all lead wiring is intact, bundle the sensor leads as required. For proper operation of
the engine, route, clamp, support, and protect the wires in the low voltage harness in a
manner to prevent chafing, fretting, and wear of the lead wires. Route and secure the
harness as described in “Harness Routing” section of Appendix C.
CAUTION: Avoid making sharp bends or kinks in the lead wires.
35.
Perform a FADEC Level I Diagnostics according to instructions in Chapter 8,
Troubleshooting. Pay particular attention to the sensor output for the repaired circuit.
