1. Disconnect the R11 connector.
2. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   L27-14 (L) - R11-2 (FS)	Always	Below 1 Ω
   L27-14 (L) - Body ground	Always	10 kΩ or higher
   L27-15 (ES2) - R11-3 (FE)	Always	Below 1 Ω
   L27-15 (ES2) - 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)	12 to 18 Ω
   1 - 2	Float level is between F (upper) and E (lower)	12 to 415 Ω (Gradually changes)
   1 - 2	Float level is E (lower)	405 to 415 Ω

OK: Go to next step 

1. Replace the combination meter assembly (meter circuit plate) to a new or a known good one. Refer to DISASSEMBLY .

   OK

   The operation of the fuel receiver gauge returns to normal.
