DTC P0460 FUEL LEVEL SENSORPFP:25060
Component DescriptionUBS00QJL
The fuel level sensor (3) is mounted in the fuel level sensor unit. The
sensor detects a fuel level in the fuel tank and transmits a signal to
the combination meter. The combination meter sends the fuel level
sensor signal to the ECM through CAN communication line.
It consists of two parts, one is mechanical float and the other is vari-
able resistor. Fuel level sensor output voltage changes depending on
the movement of the fuel mechanical float.

On Board Diagnostic LogicUBS00QJM
NOTE:

If DTC P0460 is displayed with DTC U1000, U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-151, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .

If DTC P0460 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-154, "
DTC U1010 CAN COMMUNICATION" .

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 Confirmation ProcedureUBS00QJN
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and wait maximum of 2 consecutive minutes.
