If the throttle body actuators were disabled, what would the throttle position be at?

• A. 5%
• B. 10%
• C. 15%
• D. 35%

Answer: (C)

When throttle body actuators are disabled, the throttle position is typically set to a default or fail-safe position. This is often designed to allow the engine to maintain a minimal level of operation for safety and performance reasons. In the context of the typical operation of modern electronic throttle control systems, if the actuators are inactive, the throttle may default to a position that allows sufficient airflow for idle conditions. Often, this is around a predefined percentage that ensures the engine can run but does not allow for acceleration. A common default value in these scenarios tends to be around 15% open, which is sufficient for maintaining idle and allows for quick recovery in case the actuators are re-enabled. Setting it at 15% permits the vehicle to be driven slowly and is workable for diagnostic purposes without allowing for full acceleration. Therefore, the correct response reflects this characteristic of throttle body systems when normal actuator function is interrupted.
