INSPECTION PROCEDURE
1 INSPECT FUEL SENDER GAUGE ASSY
(a) Remove the fuel sender gauge assy.
(b) Check that the float position is between E and F and mea-
sure resistance between the terminal 2 and 3 of the con-
nector.
(c) Check that the resistance value changes continuously.
Standard:
Float levelFloat position mm (in.)Resistance ()
F88.6 (3.49) 3 (0.12)4.0 1.5
1/26.4 (0.25) 3 (0.12)50.5 2.6

2 CHECK HARNESS AND CONNECTOR(BETWEEN FUEL SENDER GAUGE ASSY
AND COMBINATION METER)
(a) Remove the combination assy and fuel sender gauge.
(b) Check the continuity between the terminal 3 of the fuel
sender gauge and the terminal C10±5 of the combination
meter assy.
Standard: Continuity.
(c) Check continuity between the terminal 2 of the fuel send-
er gauge and the terminal C10±10 of the combination me-
ter assy.
Standard: Continuity.
