Inspection Procedure

INSPECT FUEL SENDER GAUGE ASSY

Remove the fuel sender gauge assy.
Check the float position is between E and F and measure the resistance between terminals 2 and 3 of the connector. Check that the resistance value changes continuously.

FLOAT POSITION SPECIFICATION

Float level	Float position mm (in.)	Resistance (Ω)
F	88.6 (3.49) +/- 3 (0.12)	4.0 +/- 1
1/2	6.4 (0.25)	59
E	102.9 (4.05) +/- 3 (0.12)	110.0 +/- 2.5

NG: REPLACE FUEL SENDER GAUGE ASSY
OK: GO TO NEXT STEP

CHECK HARNESS AND CONNECTOR (BETWEEN FUEL SENDER GAUGE ASSY AND COMBINATION METER)
1. Remove the combination assy and fuel sender gauge.
2. Check the continuity between terminal 3 of fuel sender gauge and C9-10 of combination meter assy.
  Standard: There is continuity.
3. Check the continuity between terminal 2 of fuel sender gauge and C11-4 of combination meter assy.
  Standard: There is continuity.
