If the TAC has only one sensor faulty, can the throttle actuator control be function but limited?

The throttle actuator control system can indeed function with a single sensor fault, but its capabilities may be limited. Modern throttle systems often incorporate redundancy, meaning they can rely on multiple sensors to ensure safe and effective operation. If one sensor malfunctions, the system may still receive data from the remaining operational sensors, allowing the throttle actuator to maintain control, albeit with reduced performance or functionality.

This is a safety feature designed to prevent complete failure of the throttle control system, ensuring that the vehicle can still operate in a limited capacity while the issue is addressed. Therefore, the correct answer reflects the idea that while the function may be compromised, there is still an operational capability remaining, which emphasizes the importance of safety and reliability in vehicle control systems.
