P0460 FUEL LEVEL SENSOR
P0460 FUEL LEVEL SENSOR
DescriptionINFOID:0000000005398488
The fuel level sensor 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 combina-
tion meter sends the fuel level sensor signal
to the ECM via the CAN communication line.
It consists of two parts, one is mechanical float and the ot her is variable resistor. Fuel level sensor output volt-
age changes depending on the movement of the fuel mechanical float.
DTC LogicINFOID:0000000005398489
DTC DETECTION LOGIC
NOTE:
• If DTC P0460 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P0460 is displayed with DTC P0607, first perform the trouble diagno sis for DTC P0607. Refer
to EC-351, "
DTC Logic".
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 sloshi ng signal from the sensor, fuel level sensor malfunc-
tion is detected.
DTC CONFIRMATION PROCEDURE

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
