   P0460 Fuel Level Sensor (Fuel Gauge Sending Unit) Out of Range

   DTC (PGM-FI)

   Is DTC P0460 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the gauge control module and the fuel tank unit. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot .

2. Shorted wire check (FUEL GAGE+ line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Remove the gauge control module .

   -3. Disconnect the following connectors.

   Fuel tank unit 4P connector

   Gauge control module connector A (32P)

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Fuel tank unit 4P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   Test point 1	Fuel tank unit 4P connector (female terminals) No. 2:
   Test point 2	Body ground

   Is there 1 MΩ or more?

   YES 

   Go to step 3.

   NO 

   Repair a short in the FUEL GAGE+ wire between the gauge control module and the fuel tank unit.

3. Open wire check (FUEL GAGE+ line)

   -1. Connect terminals A and B with a jumper wire.

   Terminal A	Fuel tank unit 4P connector (female terminals) No. 2:
   Terminal B	Body ground

   -2. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Fuel tank unit 4P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   	Fuel tank unit 4P connector No. 2: jumped to body ground
   Test point 1	Gauge control module connector A (32P) No. 8
   Test point 2	Body ground

   Is there 1.0 Ω or less?

   YES 

   Go to step 4.

   NO 

   Repair an open in the FUEL GAGE+ wire between the gauge control module and the fuel tank unit.

4. Open wire check (FUEL GAGE- line)

   -1. Remove the jumper wire from the fuel tank unit 4P connector.

   -2. Connect terminals A and B with a jumper wire.

   Terminal A	Fuel tank unit 4P connector (female terminals) No. 4:
   Terminal B	Body ground

   -3. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Fuel tank unit 4P connector: disconnected
   	Gauge control module connector A (32P): disconnected
   	Fuel tank unit 4P connector No. 4: jumped to body ground
   Test point 1	Gauge control module connector A (32P) No. 9
   Test point 2	Body ground

   Is there 1.0 Ω or less?

   YES 

   Go to step 5.

   NO 

   Repair an open in the FUEL GAGE- wire between the gauge control module and the fuel tank unit.

5. Fuel gauge sending unit check

   -1. Remove the jumper wire from the fuel tank unit 4P connector.

   -2. Test the fuel gauge sending unit .

   Is the fuel gauge sending unit OK?

   YES 

   Replace the gauge control module .

   NO 

   Replace the fuel gauge sending unit .
