DTC P0460 FUEL LEVEL SENSOR
DTC P0460 FUEL LEVEL SENSOR
PFP:25060
Component Description
NBS000TZ
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 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 Diagnosis Logic
NBS000U0
NOTE:
●
If DTC P0460 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to
EC-161, "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-164, "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 malfunc-
tion is detected.
DTC Confirmation Procedure
NBS000U1
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.
4.
If 1st trip DTC is detected, go to
EC-475, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

DTC P0461 FUEL LEVEL SENSOR
DTC P0461 FUEL LEVEL SENSOR
PFP:25060
Component Description
NBS000U4
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 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 Diagnosis Logic
NBS000U5
NOTE:
●
If DTC P0461 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to
EC-161, "DTC U1000, U1001 CAN COMMUNICATION LINE"
.
●
If DTC P0461 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to
EC-164, "DTC U1010 CAN COMMUNICATION"
.
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.
Overall Function Check
NBS000U6
Use this procedure to check the overall function of the fuel level sensor function. During this check, a 1st trip
DTC might not be confirmed.
WARNING:
When performing following procedure, be sure to observe the handling of the fuel.
Refer to
TESTING CONDITION:
Before starting overall function check, preparation of draining fuel and refilling fuel is required.
WITH CONSULT-II
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
EC-81, "FUEL PRESSURE RELEASE"
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 with CONSULT-II.
