Fuel Gauge Malfunction

DESCRIPTION

The combination meter assembly controls the fuel receiver gauge in accordance with the resistance of the fuel sender gauge that varies depending on the fuel remaining amount in the fuel tank.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT HARNESS AND CONNECTOR

(a) Disconnect the L5 fuel sender gauge assembly connector.
(b) Check the meter indicator conditions.
Standard:

HINT: This inspection creates an intentional short circuit between the connector terminals, to check the meter indicator operation.
NOTE: Perform the check quickly (within less than 10 seconds).
(c) Measure the voltage.
Standard Voltage:

(d) Reconnect the fuel sender gauge assembly connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT FUEL SENDER GAUGE ASSEMBLY
(a) Remove the fuel sender gauge assembly.

(b) Check that the float position is between E and F.

(d) Reinstall the fuel sender gauge assembly.
NG -- REPLACE FUEL SENDER GAUGE ASSEMBLY
OK -- Continue to next step.
3. CHECK WIRE HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY)

(a) Disconnect the E13 combination meter assembly connector.
(b) Disconnect the L5 fuel sender gauge assembly connector.
(c) Measure the resistance.
Standard resistance:

(d) Reconnect the combination meter assembly and fuel sender gauge assembly connectors.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE COMBINATION METER ASSEMBLY
