Fuel Receiver Gauge Display Malfunction |
DESCRIPTION
for Gasoline Model:
- The combination meter assembly uses the fuel sender gauge assembly and No. 2 fuel sender gauge assembly to detect the amount of fuel remaining in the fuel tank assembly. The Hall IC built into the fuel sender gauge assembly and No. 2 fuel sender gauge assembly changes the output voltage according to the amount of fuel remaining. The combination meter assembly receives fuel injection volume signals from the ECM and detects the voltage output from the fuel sender gauge assembly and No. 2 fuel sender gauge assembly and operates the fuel receiver gauge.
for HV Model:
- The combination meter assembly uses the fuel sender gauge assembly to detect the amount of fuel remaining in the fuel tank assembly. The Hall IC built into the fuel sender gauge assembly changes the output voltage according to the amount of fuel remaining. The combination meter assembly receives fuel injection volume signals from the ECM and detects the voltage output from the fuel sender gauge assembly and operates the fuel receiver gauge.

CAUTION / NOTICE / HINT
CAUTION:
Be careful of flames.
NOTICE:
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
