7.
Check “FUEL LEVEL SE” output voltage and note it.
8.
Select “FUEL PUMP” in “ACTIVE TEST” mode with CONSULT-
II.
9.
Touch “ON” and drain fuel approximately 30 (7-7/8 US gal, 6-
5/8 Imp gal) and stop it.

DTC P0462, P0463 FUEL LEVEL SENSOR
PFP:25060
Component Description
NBS000U9
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
NBS000UA
NOTE:
●
If DTC P0462 or P0463 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 P0462 or P0463 is displayed with DTC U1010, first perform the trouble diagnosis for DTC
U1010. Refer to
EC-164, "DTC U1010 CAN COMMUNICATION"
.
This diagnosis indicates the former, to detect open or short circuit malfunction.
DTC Confirmation Procedure
NBS000UB
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.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11V at ignition
switch ON.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Wait at least 5 seconds.
4.
If 1st trip DTC is detected, go to
EC-479, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.

road test is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1.
Start engine (VDC switch OFF).
2.
Read “VHCL SPEED SE” in “DATA MONITOR” mode with CONSULT-II. The vehicle speed on CONSULT-
II should exceed 10 km/h (6 MPH) when rotating wheels with suitable gear position.
If NG, go to
EC-482, "Diagnostic Procedure"
If OK, go to following step.
3.
Select “DATA MONITOR” mode with CONSULT-II.
4.
