1. Disconnect the N11 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
   I18-18 (FR) - N11-2 (FS)	Always	Below 1 Ω
   I18-18 (FR) - Body ground	Always	10 kΩ or higher
   I18-17 (FE) - N11-3 (FE)	Always	Below 1 Ω
   I18-17 (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 for 2AR-FE. Refer to REMOVAL for 2GR-FE.

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
