DTC DETECTION LOGIC
NOTE:
When the vehicle is parked, naturally the fuel level in the fuel tank is stable. It means that output signal of the fuel level sensor does not change. If ECM senses sloshing signal from the sensor, fuel level sensor malfunction is detected.
| DTC No. | Trouble diagnosis name | DTC detecting condition | Possible cause |
| P0460 | FUEL LEV SEN SLOSH (Fuel level sensor circuit noise) | Even though the vehicle is parked, a signal being varied is sent from the fuel level sensor to ECM. |
