Fuel System 1 Closed at Michael Schiller blog

Fuel System 1 Closed. the only problem is that the vehicle speed sensor doesn't work on the older tune. the fuel system 1 ol fault occurs when the control system does not switch from an open to a closed loop as the engine temperature rises, preventing the system from making correct fuel adjustments and causing your engine to run rich. I did a tune compare between. fuel system ol faults signal that this system isn’t working as it should, causing symptoms like poor fuel efficiency, rough idling, and emissions troubles. It happens when a circuit breaks or an electrical interruption occurs. a vehicle’s computer flags the “fuel sys 1 cl” when there’s an issue with the fuel system’s operation in the closed. One of the primary culprits behind fuel system ol faults is malfunctioning oxygen sensors (o2 sensors). what does fuel sys 1 cl mean?
