Torque and Overspeed Sensors color?

• A. Yellow Cable
• B. Green Cable
• C. Blue Cables
• D. White Cables

Answer: (C)

Color coding of sensor cables helps maintenance quickly verify connections for critical measurements. Torque and overspeed sensors feed the engine/drive system and control systems with essential data, so their wires are marked distinctly to prevent cross-connection. The blue cables are designated for the torque and overspeed sensor circuits, making it clear which harness connects to those sensors. This distinction is crucial because these sensors provide real-time data used to manage engine torque and to prevent rotor overspeed; misconnecting them could send improper signals and compromise safety. Other colored cables (yellow, green, white) are assigned to different sensor circuits, so they wouldn’t be used for the torque and overspeed sensors.
