🔌 Function

Controls the flow through the inlet path on command from the control system, regulating how much air reaches the engine.

⚠️ Common Signs of Failure

• Poor or uneven running, or the engine sitting in a derated mode
• Fault codes pointing at throttle position or air flow
• Actuator sluggish, noisy or not moving through its full travel
• Butterfly and bore found coked or gummed so movement is stiff
• Shaft bushes found worn, giving play in the plate

🛠️ Service Notes

• Check the wiring, connector and supply to the actuator before condemning the unit - a signal fault presents exactly like a failed throttle
• Renew the flange gaskets or seals when refitting, and have the control system relearn the throttle position if the procedure calls for it
