1. Disconnect the L13 connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   F4-27 (L) - L13-2 (FS)	Always	Below 1 Ω
   F4-27 (L) - Body ground	Always	10 kΩ or higher
   F4-30 (FE) - L13-3 (FE)	Always	Below 1 Ω
   F4-30 (FE) - Body ground	Always	10 kΩ or higher

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)	13.5 to 16.5 Ω
   1 - 2	Float level is between F (upper) and E (lower)	13.5 to 414.5 Ω (Gradually changes)
   1 - 2	Float level is E (lower)	405.5 to 414.5 Ω

OK: Go to next step 

1. Visually check for deformation on the fuel suction pump and gauge assembly connector.

   OK

   There is no deformation.
