P0460 FUEL LEVEL SENSOR

DTC Logic

INFOID:0000000009020819

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 diagnosis 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 sloshing signal from the sensor, fuel level sensor malfunc-

tion is detected.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and wait maximum of 2 consecutive minutes.

2. Check 1st trip DTC.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-325, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009020820

1.

CHECK COMBINATION METER FUNCTION

Refer to 

MWI-15, "CONSULT Function"

.

Is the inspection result normal?

YES

>> CHECK INTERMITTENT INCIDENT. Refer to 

GI-41, "Intermittent Incident"

.

NO

>> Refer to 

MWI-45, "Component Function Check"

.

DTC No.

(Fuel level sensor circuit noise)

Even though the vehicle is parked, a 
signal being varied is sent from the 
fuel level sensor to ECM.

• Harness or connectors

(The CAN communication line is open or shorted)

• Harness or connectors

(The sensor circuit is open or shorted)
