Does Peugeot 408 computer need to be replaced when detecting throttle failure?

With the detector, there is usually an option of throttle opening value, and there should also be an option of idling when the car is driving. If the idle option shows partial load without stepping on the accelerator, it is wrong. Then, if the car is not driving, open the key door, and you will see the standard opening value of the throttle in the throttle option.
