Under what circumstances should the throttle assembly be replaced?

If the throttle valve is broken, the EPC light on the instrument will light up. This indicates that there is something wrong with the electronic throttle control system.

The cold car didn't start well, so the throttle broke in. Idle speed is unstable. Black smoke.

If the vehicle cannot be started, the diagnostic instrument will check and the engine system will report that the throttle valve is damaged or the sensor is unreliable.

The failure of flameout often occurs when the vehicle is taxiing.

Measure the throttle opening with a diagnostic instrument to see if it is within the normal range. If the throttle angle is still too large after cleaning, it needs to be replaced.

The throttle is basically not set successfully. After troubleshooting the wiring, battery and engine control unit, the throttle valve needs to be replaced.
