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
.
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
.
NO
>> INSPECTION END
Diagnosis Procedure
INFOID:0000000009267201
1.
CHECK COMBINATION METER FUNCTION
(TYPE B).
Is the inspection result normal?
YES
>> Check intermittent incident. Refer to
GI-45, "Intermittent Incident"
.
NO
>> Refer to
MWI-46, "Component Function Check"
(TYPE B). Check the vehicle type to confirm the service information in MWI section. Refer
to
.

Trouble diagnosis name
(Trouble diagnosis content)
DTC detecting condition
Possible cause
P0460
FUEL LEV SEN SLOSH
(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)

INFOID:0000000009267202
DTC DETECTION LOGIC
NOTE:
• If DTC P0461 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P0461 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer
Driving long distances naturally affect fuel gauge level.
This diagnosis detects the fuel gauge malfunction of the gauge not moving even after a long distance has
been driven.
DTC CONFIRMATION PROCEDURE
1.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-324, "Component Function Check"
Use component function check to check the overall function of the fuel level sensor function. During this
check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
.
Component Function Check
INFOID:0000000009267203
1.
PRECONDITIONING
WARNING:
When performing following procedure, be sure to observe the handling of the fuel. Refer to
TESTING CONDITION:
Before starting component function check, preparation of draining fuel and refilling fuel is required.
Do you have CONSULT?
YES
>> GO TO 2.
NO
>> GO TO 3.
2.
PERFORM COMPONENT FUNCTION CHECK
With CONSULT
NOTE:
Start from step 10, if it is possible to confirm that the fuel cannot be drained by 30 (7-7/8 US gal, 6-5/
8 Imp gal) in advance.
1. Prepare a fuel container and a spare hose.
2. Release fuel pressure from fuel line, refer to
.
3. Remove the fuel feed hose on the fuel level sensor unit.
4. Connect a spare fuel hose where the fuel feed hose was removed.
5. Turn ignition switch OFF and wait at least 10 seconds then turn ON.
6. Select “FUEL LEVEL SE” in “DATA MONITOR” mode of “ENGINE” using CONSULT.
7. Check “FUEL LEVEL SE” output voltage and note it.
8. Select “FUEL PUMP RELAY” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.
9. Touch “ON” and drain fuel approximately 30 (7-7/8 US gal, 6-5/8 Imp gal) and stop it.
DTC No.

10. Check “FUEL LEVEL SE” output voltage and note it.
11. Fill fuel into the fuel tank for 30 (7-7/8 US gal, 6-5/8 Imp gal).
12. Check “FUEL LEVEL SE” output voltage and note it.
13. Confirm whether the voltage changes more than 0.03 V during step 7 to 10 and 10 to 12.
Is the inspection result normal?
YES
