DTC P0460: Fuel Level Sensor Circuit Malfunction: Procedure
- Remove rear seat disconnect the fuel pump module connector, measure resistance between the fuel pump harness connector terminal No. 2 and ECM harness connector terminal No. 82. See FUEL PUMP WIRE COLORS table. See Figure . If measured resistance less than one ohm, go to next step. If not, check for open or high resistance in wire between fuel pump and ECM terminal No. 82. Inspect connectors for loose, damaged or corroded terminals. If problem exists, repair wiring harness and appropriate connector as necessary.
- Measure resistance between the fuel pump harness connector terminal No. 2 and ground. If measured resistance is infinite, go to next step. If not, check for short to ground in wire between fuel pump and ECM harness connector terminal No. 82. Repair wiring harness as necessary.
- Measure resistance between the fuel pump harness connector terminal No. 3 and ground. If measured resistance is less than one ohm, go to next step. If measured resistance is not less than one ohm, check for open or high resistance in wire between fuel pump harness connector terminal No. 3 and ground. Inspect connectors for loose, damaged or corroded terminals. If problem exists, repair wiring harness and as necessary appropriate connector as necessary.
- Remove fuel pump unit from fuel tank, reconnect fuel pump connector. Turn ignition to on and observe low fuel indicator. If low fuel indicator illuminate, thoroughly inspect connectors for loose, damaged or corroded terminals between fuel pump and ECM. If problem exists, repair wiring harness and appropriate connector as necessary. If low fuel indicator does not illuminate, turn ignition off and jumper fuel pump terminal No. 2 and ground. Turn ignition on, observe low fuel indicator. If low fuel indicator does not illuminate, replace LFI bulb and retest.
