DTC P0460 FUEL LEVEL SENSOR

EC-451

2007 Pathfinder

DTC P0460 FUEL LEVEL SENSOR

PFP:25060

Component Description

UBS00KAC

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

UBS00KAD

NOTE:

●

If DTC P0460 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to

EC-154, "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-157, "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

UBS00KAE

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

Turn ignition switch ON.

Select “DATA MONITOR” mode with CONSULT-II.

Start engine and wait maximum of 2 consecutive minutes.

If 1st trip DTC is detected, go to

EC-452, "Diagnostic Procedure"

WITH GST

Follow the procedure “WITH CONSULT-II” above.

WARNING:

When performing following procedure, be sure to observe the handling of the fuel. Refer to

FL-12,

"FUEL TANK"

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.
