On Board Diagnosis Logic

NOTE:
  • If DTC P0460 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC U1000, U1001. Refer to U1000, U1001 CAN COMM CIRCUIT .
  • If DTC P0460 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to U1010 CONTROL UNIT (CAN) .

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.
