Note. For malfunctions potentially caused by insufficient fuel (e.g. combustion misfires) the DTC "P1250, Fuel Level Too Low" is also indicated. This means that combustion misfires could not be recognized on account of a technical malfunction, but rather because there is/was too little fuel in fuel tank.
