Description
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 via the CAN communication line.
It consists of two parts, one is mechanical float and the other is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.
DTC Logic
DTC DETECTION LOGIC
NOTE:
Refer to EC-161, "DTC Logic".
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 EC-374, "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.
Component Function Check
1.PRECONDITIONING
WARNING: When performing the following procedure, always observe the handling of the fuel. Refer to FL-6, "Removal and Installation". TESTING CONDITION: Before starting component function check, preparation of draining fuel and refilling fuel is required.
2.PERFORM COMPONENT FUNCTION CHECK
With CONSULT
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.
3.PERFORM COMPONENT FUNCTION CHECK
Without CONSULT
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.
