METER / GAUGE SYSTEM > Fuel Receiver Gauge Malfunction |
for Preparation Click here
DESCRIPTION
- The fuel sender gauge has a variable resistance mechanism. The resistance decreases when the fuel amount increases, and the resistance increases when the fuel amount decreases. The fuel receiver gauge changes based on the resistance of the fuel sender gauge.
- NOTICE:
- When the combination meter is removed or replaced, its connector is disconnected or fuel is added, the fuel receiver gauge display will return to normal within a maximum of 16 minutes after the ignition switch is turned to ON or when vehicle speed is input.

INSPECTION PROCEDURE
1.CHECK HARNESS AND CONNECTOR (COMBINATION METER - FUEL SUCTION WITH PUMP AND GAUGE TUBE OR FUEL TANK VENT TUBE) |
Disconnect the C25 combination meter assembly connector.
Disconnect the F15 fuel suction with pump and gauge tube assembly*1 or F13 fuel tank vent tube sub-assembly*2 connector.
- *1: for 1TR-FE, 2TR-FE, 1GR-FE
- *2: for 1KD-FTV, 2KD-FTV, 5L-E
- *1: for 1TR-FE, 2TR-FE, 1GR-FE
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
for 1TR-FE, 2TR-FE, 1GR-FE Tester Connection Condition Specified Condition C25-2 (ES) - F15-3 (FE) Always Below 1 Ω C25-3 (L) - F15-2 (FS) Always Below 1 Ω C25-2 (ES) - C25-3 (L) Always 10 kΩ or higher C25-2 (ES) - Body ground Always 10 kΩ or higher C25-3 (L) - Body ground Always 10 kΩ or higher for 1KD-FTV, 2KD-FTV, 5L-E Tester Connection Condition Specified Condition C25-2 (ES) - F13-3 (FE) Always Below 1 Ω C25-3 (L) - F13-2 (FS) Always Below 1 Ω C25-2 (ES) - C25-3 (L) Always 10 kΩ or higher C25-2 (ES) - Body ground Always 10 kΩ or higher C25-3 (L) - Body ground Always 10 kΩ or higher

2.INSPECT FUEL SUCTION WITH PUMP AND GAUGE TUBE OR FUEL TANK VENT TUBE |
Remove the fuel suction with pump and gauge tube assembly*1 or fuel tank vent tube sub-assembly*2.
- *1: for 1TR-FE, 2TR-FE, 1GR-FE
- *2: for 1KD-FTV, 2KD-FTV, 5L-E
- *1: for 1TR-FE, 2TR-FE, 1GR-FE
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition A-2 - B-2 Always Below 1 Ω A-3 - B-1 Always Below 1 Ω A-2 - A-3 Always 10 kΩ or higher
