Warm-ups Since Trouble
Codes Cleared
Gauge name Range Units Abbreviation
Warm ups - TC
cleard
0 to 255 Warm ups Wups TC
Once trouble codes are cleared, this gauge counts the number of times the engine
temperature rises from 40 F to 160 F, or 140F for diesels. The max count value
is 255. Once 255 is reached, the count will remain at 255 until trouble codes are
again cleared.
Distance Since Trouble
Codes Cleared
Gauge name Range Units Abbreviation
mi since TC cleard 0 to 40,722 miles mi TC
km since TC cleard 0 to 65,535 kilometers km TC
Once trouble codes are cleared, this gauge measures the number of miles driven.
The max value is 40,722 miles. Once 40,722 miles is reached, the count will
remain at 40,722 until trouble codes are again cleared.
Evaporative
Purge %
Gauge name Range Units Abbreviation
Evaporative Purge % 0 to 100 % Evap %Prg
Commanded Evaporative Purge percent. A value of 0% is no flow, and a value of 100% is
wide open maximum flow. This is a commanded value indicating that the ECM is requesting
the % flow. The actual flow may not match.
Fuel Level %
Gauge name Range Units Abbreviation
Fuel Level % 0 to 100 % Fuel Lvl%
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.
Evaporative
Vapor Pressure
Gauge name Range Units Abbreviation
Evap Vapor PSI -1.188 to 1.188 PSI Evp PSI
Evap Vapor Pa -8192 to 8192 Pa Evp Pa
This pressure value is normally obtained from a sensor located in the fuel tank or a sensor in
an evaporative system vapor line.
Barometric
Pressure
Gauge name Range Units Abbreviation
Barometric inHg 0 to 75.3 inHg Baro inHg
Barometric kPa 0 to 255 kPa Baro kPa

Cat B1S1
Cat Bank 2 Sensor 1 Temperature Cat B2S1
Cat Bank 1 Sensor 2 Temperature Cat B1S2
Cat Bank 2 Sensor 2 Temperature Cat B2S2
Catalytic Converter temperature. Bank1 is the Cat through which the exhaust from cylinder #1
passes. Typical temps should not exceed 900ºC / 1650ºF. Excess temps can damage the
converter.
ECM Battery
Voltage
Gauge name Range Units Abbreviation
ECM Battery Voltage 0 to 65.535 Volts Bat volt
Voltage as measured at and by the Electronic Control Module. This is typically the same as
Battery voltage. See also UG Battery Voltage.
Load absolute %
Gauge name Range Units Abbreviation
Load absolute %
0 to 95
0 to 400
% Load abs%
Alternate to “% Engine Load” this gauge ranges from 0 to 95% for normally aspirated engines
and 0 to 400% for boosted engines. This gauge is linearly correlated to Brake Torque
