The Fuel Level Rationality detects that there is no increase in the main fuel tank level when there is a decrease in the Auxiliary Fuel tank level. The BCM reports Fuel Level Sensor information to the PCM over the CAN Bus. This DTC will be set if the Fuel Pump 2 On/Off Control circuit voltage is outside of a calibrated threshold for a calibrated amount of time.
