Self-diagnosis Detection Logic

Diagnosis Procedure

a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the fuel level sensor and fuel pump connector

B-038.

d. Check the wire harness, connector and terminals for

deformation, bend or damage.

a. Connect the negative battery cable.
b. Turn ignition switch to ON.
c. Check the remaining oil amount segments from fuel

gauge in the instrument cluster.

d. Turn ignition switch to LOCK.
e. Disconnect the negative battery cable.
f. Disconnect the fuel level sensor and fuel pump connector

B-038.

g. Using a digital multimeter, measure the resistance

between terminal 1 and terminal 2 of fuel level sensor.

h. Check if fuel level sensor is normal according to the

correspondence between fuel amount segments and
standard resistance of fuel level sensor as shown in the
table below.
