The Fuel Level gauge indicates the number of remaining gallons/liters in the fuel tank. This
value is determined one of two ways, depending on the
Fuel Sender Mode
Setting. When the
Fuel Sender Mode is set to
Disabled
or
Smart
,
the fuel level is calculated based upon fuel used.
When the Fuel Sender Mode is set to
Enabled
, the fuel level is calculated directly from the fuel
tank sensor.
When the
Fuel Sender Mode
is set to
Disabled
, it is necessary to inform UltraGauge manually
that the tank has been filled. This is done via the menu system by selecting
from
the Gauge screen
.
This can also be accomplished by pressing and holding the
UP
key for three
seconds while UltraGauge is showing the Main Gauge display. Once Fuel Fill-Up is done, the
Fuel Level, TTE and DTE will adjust.
To determine if your vehicle supports a fuel level sensor, select
. If the response is “
No Fuel Sensor Found
”, no sensor is
available via the OBDII. Otherwise, the vehicle supports the sensor and UltraGauge will
automatically use this sensor to determine the Fuel Level.
Some vehicles incorrectly report the support of a fuel level sensor. For those vehicles the
reported fuel level will be frozen or inaccurate. In this situation, the use of the fuel level sensor
must be disabled. To disable the fuel level sensor, select
Then select
Disabled.
NOTE:
There can be more fuel than indicated when the sensor reports 100% full, and there can be a
reserve of fuel when the sensor reports 0 gallons remaining. When the fuel level is calculated,
fuel level can report a negative number indicating that you have used more fuel than your
reported fuel tank size. This is normal as there is always an unreported reserve. Vehicle Tank
sensors are also notoriously inaccurate by as much as +-3 gallons. It is recommended to set the
Fuel Sender setting to either disabled or Smart. See the Fuel Sender Setting section for
additional details

This is the raw output of the fuel tank level sensor. However, this input is averaged such that
sloshing will not cause erratic behavior. The fuel sensor is sampled every second and averaged
with the previous 30 samples.
