METER: METER / GAUGE SYSTEM: Fuel Gauge Malfunction
- Fuel Gauge Malfunction

DESCRIPTION

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

WIRING DIAGRAM

Refer to DTC B1500 B1500.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT

(a) Check if DTC B1500 is output Reading and Clearing Diagnostic Trouble Codes.
