Fuel Level Indicator Inspection

If the fuel level indicator light does not function properly,
check the fuel level gauge and its lead wire/coupler.
If the fuel level gauge and its lead wire/coupler are
functioning properly, replace the combination meter with
a new one.

Fuel Level Gauge Inspection

Inspect the fuel level gauge in the following procedures:
1) Remove the fuel pump. Refer to "Fuel Pump
Disassembly and Assembly in Section 1G (Page 1G-
11)".
2) Measure the resistance at each fuel level gauge in
float position. If the resistance is incorrect, replace
fuel level gauge with a new one.

Speedometer Inspection

If the speedometer, odometer or tripmeter does not
function properly, inspect the speed sensor and the
coupler connections. If the speed sensor and coupler
connections are OK, replace the combination meter unit
with a new one. Refer to "Combination Meter Removal
and Installation (Page 9C-2)".
