Main Fuel Gauge Sender

Using an ohmmeter, measure the resistance between terminals 1 and 3 of sender connector (A) at each float level.

Also check that the resistance changes smoothly when the float is moved from "E" to "F".

RESISTANCE SPECIFICATION

Position	Segment	Resistance (Ω)	Liter (l )
Warning lamp ON	1 SEG	170Ω ± 2Ω	8.5
Warning lamp OFF	2 SEG	146.7Ω	13.9
1/2	6 SEG	72.7Ω	35
F	12 SEG	15Ω ± 1Ω	66

If the height resistance is unsatisfied, replace the fuel sender as an assembly.

CAUTION: After completing this test, wipe the sender dry and reinstall it in the fuel tank.
