1. Disconnect the P7 fuel suction tube with pump and gauge assembly connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   H14-26 (FR) - P7-2 (FS)	Always	Below 1 Ω
   H14-26 (FR) - Body ground	Always	10 kΩ or higher
   H14-27 (FE) - P7-3 (FE)	Always	Below 1 Ω
   H14-27 (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 [06/2012 - ] .

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
