2. Measure the resistance according to the value(s) in the table below.

   Standard resistance

   Tester Connection	Condition	Specified Condition
   E1-34 (FR) - 2	Always	Below 1 Ω
   E1-34 (FR) - Body ground	Always	10 kΩ or higher
   E1-19 (FE) - 1	Always	Below 1 Ω
   E1-19 (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 2GR-FE. Refer to REMOVAL for 1AR-FE.
