Ford Flex orange engine light on with code P2068 indicating fuel level sensor 'B' circuit issue and incorrect gauge reading on Ford Flex

Some Ford Flex owners report experiencing issues related to the P2068 diagnostic trouble code, which indicates a problem with the Fuel Level Sensor 'B' Circuit. Symptoms include the check engine light illuminating on the dashboard and erratic fuel gauge readings, such as showing a full tank when it is empty or vice versa. Additionally, some owners notice the fuel gauge moving unpredictably or displaying incorrect levels, with alarms sounding if the fuel light blinks. Diagnosing this issue typically involves scanning for codes and inspecting the fuel level sensor, wiring, and connectors for damage or corrosion.
