P0461 FUEL LEVEL SENSOR

Component Description

INFOID:0000000006158755

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

INFOID:0000000006158756

NOTE:

• If DTC P0461 is displayed with DTC U0101 or U1001, first perform the trouble diagnosis for DTC

U0101, U1001. Refer to 

EC-140

.

• If DTC P0461 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer

to 

EC-344

.

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

INFOID:0000000006158757

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 

FL-6,

"Removal and Installation"

.

TESTING CONDITION:

Before starting overall function check, preparation of draining fuel and refilling fuel is required.

 WITH CONSULT-III

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-473, "Fuel Pressure Check"

.

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-III.

7. Check “FUEL LEVEL SE” output voltage and note it.

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

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 0.03V during step 7 to 10 and 10 to 12.

If NG, go to 

EC-328, "Diagnosis Procedure"

.

 WITH GST

NOTE:
Start from step 8, 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-473, "Fuel Pressure Check"

.

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 ON.
6. Drain fuel by 30   (7-7/8 US gal, 6-5/8 Imp gal) from the fuel tank using proper equipment.

7. Confirm that the fuel gauge indication varies.
8. Fill fuel into the fuel tank for 30   (7-7/8 US gal, 6-5/8 Imp gal).

9. Confirm that the fuel gauge indication varies.

10. If NG, go to 

EC-328, "Diagnosis Procedure"

.
