IMPORTANT
Since fuel gauge is purposely designed to update
the display after a certain delay, changing the
potentiometer value will not quickly show up on
gauge display as you would expect. Proceed as
follows for the test.
1. Ensure potentiometer is not connected to
circuit.
2. Set potentiometer to desired resistance value.
3. Connect potentiometer to circuit.
4. Ensure fuel gauge display is OFF.
5. Install safety lanyard to DESS post.
6. Read fuel gauge.
7. Repeat steps 1 to 6 for each potentiometer
setting.
If out of specification, check wiring harness/con-
nectors. If wiring/connectors are good, try a new
Information Center.
If everything test good and fuel gauge still does
not work, verify continuity of circuit inside VCM
as follows.

Water Temperature (L temp)
Water Temperature Sensor
NOTE: The water temperature sensor is integrat-
ed with the speed sensor.
Select the water temperature mode in the Infor-
mation Center.
Spray the speed sensor with water using a gar-
den hose. The temperature reading on the Infor-
mation Center should adjust to the water temper-
ature.
Otherwise, disconnect speed sensor connector.
Measure sensor resistance.
