Engine Low Voltage Harness Lead Wire Repair and Sensor 

Replacement  

The low voltage harness is made up a several types of lead wires and sensors which 
include Exhaust Gas Temperature (EGT) Sensors, the Cylinder Head Temperature (CHT) 
Sensors and the Manifold Air Temperature (MAT) Sensors. The non-EGT sensors are the 
CHT Sensors and the MAT Sensors. The fuel injector solenoids also are hardwired to the 
engine low voltage harness.  
 
Faults detected in the EGT, MAT, and CHT sensors constitute faults in the engine low 
voltage harness and require lead wire repair or sensor replacement. If a wire in the engine 
low voltage harness is damaged, it may be repaired or sent to the factory or an authorized 
service center for repair.  
 
However, the EGT Sensor lead wires are K-type thermocouples and have chromel and 
alumel conductors whereas the remaining engine low voltage harness conductors are 
copper and referred to as “Non-EGT” lead wires. Due to physical differences, separate 
repair procedures are provided: 

NOTE: Sensor/Wire Splice Kits for EGT and Non- EGT wiring are 
available from TCM: Select the proper splice kit and follow the 
respective procedure when repairing lead wires and sensors on the 
Engine Low Voltage Harness. 

CAUTION: Use the proper splice kit for EGT sensors or lead wires. 
Using an EGT Splice Kit on a non-EGT sensor or lead wire will 
result in abnormal engine operation and may cause engine damage. 

Engine low voltage harness sensors are field replaceable, provided the failed sensor or 
wire is greater than 12 inches (30 cm) from the 50-pin ECU connector. To replace an 
EGT sensor or repair the EGT wiring in the engine low voltage harness wiring, refer to 
Section  10-5.1, “EGT Sensor and Lead Wire Replacement.” To replace a Non-EGT 
sensor or repair the copper sensor wiring in the engine low voltage harness wiring, refer 
to Section 10-5.2, “Non-EGT Sensor and Lead Wire Replacement.”
