What is the reason why the fuel filler door of Dongfeng Peugeot 206 idling at 2000 rpm is normal without speed increase, continuous battery line opening, reconnection and flameout for five minutes?

Hello, according to your description, it may be caused by the unreliable electronic throttle signal. I suggest you find a decoder to read the two signals of the throttle. Is it normal? Under normal circumstances, the sum of the sexes of the throttle should be equal to five volts, otherwise it will report that the throttle signal is not credible, resulting in an increase in idle speed and inability to refuel.

I hope I can help you.
