1. Disconnect the M22 fuel sender gauge assembly connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   G1-2 (L) - M22-2 (FS)	Always	Below 1 Ω
   G1-2 (L) - Body ground	Always	10 kΩ or higher
   M22-3 (FE)- Body ground	Always	Below 1 Ω

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the fuel sender gauge assembly. Refer to REMOVAL .

2. Check that the float moves smoothly between E and F.
3. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   1 - 2	Float level is F (upper)	12.0 to 18.0 Ω
   1 - 2	Float level is between F (upper) and E (lower)	12.0 to 415.0 Ω (Gradually changes)
   1 - 2	Float level is E (lower)	405.0 to 415.0 Ω
