## Functions
The electronic throttle body relies on its throttle position sensor to adjust intake airflow based on the engine’s power demand. This precise air regulation effectively boosts engine output and delivers snappier vehicle acceleration.
## Working Principle
When you step on the accelerator pedal, the internal butterfly valve opens to draw air into the engine. Releasing the pedal closes the valve to restrict airflow entering combustion chambers. This airflow control governs engine RPM and ultimately the driving speed of the vehicle.
## Faults It Resolves
This replacement part fixes common issues including weak acceleration, unstable idle, failure to start under acceleration, engine stalling, and illuminated electronic throttle warning lights.
