What is the reason why the throttle fault light is on?

The reason why the fault light of this component is on is that the throttle is damaged, and the throttle sensor and throttle circuit are faulty.

1. Throttle damage: If the throttle is damaged, it can't be opened or closed normally, which will affect the working state of the engine and eventually cause the throttle fault light to light up.

2. Throttle sensor failure: Throttle sensor is a component used to detect throttle position. If the sensor fails, it will also cause the throttle fault light to light up.

3. Throttle circuit fault: If the circuit of the engine control system fails, it may also cause the throttle fault light to light up.
