The DTC "Fuel level too low" is stored in connection with combustion misfires or malfunctions relating to oxygen sensor
control when there is/was too little fuel in fuel tank. The DTC is stored as a static malfunction and is not switched to sporadic
even if fuel tank has been filled with fuel in the meantime.
