NO	Description	NO	Description
1	Gauge signal GND	4	Fuel pump (+)
2	-	5	Fuel pump GND
3	Gauge signal (+)	-	-

Also Check That The Resistance Changes Smoothly When The Float Is Moved From "E" To "F"

Supervision

Position	Liter (l )	U.S. gal.	Resistance (Ω)
Warning lamp blink	5	1.32	200+5/-2Ω
1/12 (E)	8.5	2.24	170±2Ω
6/12	35	9.24	72.7Ω
12/12 (F)	66	17.4	8±1Ω

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.
