P0005 Fuel Shutoff Valve “A” Control Circuit/Open Fault Code

When you take your foot off the gas while driving with your vehicle, the cut-off system is activated. The purpose of this system is to provide the power required for the engine to start, especially when going downhill, from the weight of the vehicle itself. At this time, the fuel sent to the engine is completely cut off and the car proceeds with zero fuel consumption. Whenever you press the accelerator pedal, fuel starts to be sent again and this situation continues continuously.
