How to judge that the throttle is broken?

If there is something wrong with the electronic throttle control system, the EPC light on the instrument will light up.

It is difficult to start the cold car, so the air valve needs to be started. Idle speed is unstable, and it will emit black smoke.

If the vehicle can't start, you can check the engine system with a diagnostic instrument to see if the throttle is damaged or the sensor is unreliable.

The flameout fault often occurs when the vehicle is running.

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 the throttle, you need to replace the throttle.

If there is a problem with the basic setting of the throttle, it is necessary to eliminate the possible causes such as wiring problems, battery problems and engine control unit. If the problem persists, the throttle valve needs to be replaced.
