WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.READ VALUE USING INTELLIGENT TESTER (FUEL SENDER GAUGE) |
Operate the intelligent tester according to the display and select the Data List ().
Combination Meter| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| Fuel Input | Fuel sender gauge (main) input signal/Min.: 0, Max.: 127.5 | Fuel sender input value | Unit: L |
- OK:
- Fuel value displayed on the intelligent tester is almost the same as needle indication.

| 2.CHECK HARNESS AND CONNECTOR (COMBINATION METER - PUMP AND GAUGE AND BODY GROUND) |
Disconnect the E7 and E8 combination meter assembly connectors.
Disconnect the N1 fuel suction with pump and gauge tube assembly connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
| Tester Connection | Condition | Specified Condition |
| E8-9 (L) - N1-2 (FS) | Always | Below 1 Ω |
| E8-21 (E) - N1-3 (FE) | Always | Below 1 Ω |
| E7-15 (ET) - Body ground | Always | Below 1 Ω |
| E8-9 (L) or N1-2 (FS) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
|
| 3.INSPECT FUEL SUCTION WITH PUMP AND GAUGE TUBE ASSEMBLY |
Remove the fuel sender gauge assembly.
