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 to "DTC Logic" For USA and Canada.
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 "Component Function Check" .
Use component function check to check the overall function of the fuel level sensor. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal?
YES- INSPECTION END
NO- Proceed to "Diagnosis Procedure" .


Component Function Check


1. PRECONDITIONING


WARNING:
When performing the following procedure, always observe the handling of the fuel. Refer to "General Precautions" General Precautions.
TESTING CONDITION:
Before starting component function check, preparation of draining fuel and refilling fuel is required.
- GO TO 2.

2. PERFORM COMPONENT FUNCTION CHECK

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.

9.Confirm that the fuel gauge indication varies.
Is the inspection result normal?
YES- INSPECTION END
NO- Proceed to "Diagnosis Procedure" .


Diagnosis Procedure


1. CHECK DTC WITH "COMBINATION METER"

Refer to "CONSULT Function" Combination Meter.
Is any DTC detected?
