A
rent storage being used by
module, but a fault with at
least one O2 sensor has
been detected. The control
system may be using single
O2 for fuel control calcula-
tio ns.
IAT TEMP (- 40 – 215ºC) or (- 40 – 419ºF)
Intake Air Temperature is a measure of
intake air temperature to determine cor-
rect air/fuel ratios and spark timing oper-
ations.
IGN ADV (- 64 – 63.5º)
Ignition Timing Advance for cylinder is a
signal of how much spark advance to add
to base engine timing (expressed in
crankshaft degrees).
LT FL FTRM (-100 – 99.22%)
Long Term Fuel Trim Bank is the fuel mix-
ture adjustment. The mixture can range,
with midpoint being 0.
✓
Positive reading indicates
module commanded a
long-term rich mixture correc-
tion in response to a lean
operating condition. A nega-
tive reading indicates module
has commanded a long-term
lean mixture in response to a
rich operating condition.
MAF (0 – 655.35 g/s) or (0 – 86.5 lb/min)
Mass Air Flow Rate indicates the mass of
air entering engine.
MAP (0 – 255 kPa) or (Hg)
Intake Manifold Absolute Pressure dis-
plays manifold pressure.
MIL DIST (0 – 65,535 km) or (0 – 40,722
miles)
Distance Traveled while Malfunction Indi-
cator Lamp is Active is a counter that dis-
plays distance traveled since the MIL “or
Check Engine or Service Engine Soon”
light came on.
MIL STAT (ON or OFF)
Monitor Status Data Trouble Code state
that module is commanding Malfunction
Indicator Lamp to be on if problem exists.
MIL TIME (0 – 65,535 min) or (0 –
1092.25Hrs)
Distance Since Monitor Status Data Trou-
ble Code is the distance traveled since the
MIL “or Check Engine or Service Engine
Soon” light came on.
O2Sxy (0 – 1.275V)
Oxygen Sensor Output Voltage is the volt-
age generated from the oxygen sensor to
increase and decrease the amount of
exhaust gas.
O2Sxy (- 128 – 127.996mA)
Oxygen Sensor Output Amp is used for
linear or wide ratio oxygen sensors to
increase and decrease the amount of
exhaust gas
OBD2 STAT (CA, OBDI, US, NONE, EU
and/or JA)
On Board Diagnostic shows what vehicle was
made for.
CA - Indicates test vehicle meets
California on board diag-
nostic ARB requirements
OBD I - Indicates test vehicle does
not meet OBDII require-
ments.
US - Indicates test vehicle meets
Federal EPA requirements.
NONE - Indicates test vehicle is not
on board diagnostic compli-
ant.
EU - Indicates test vehicle meets Eu-
ropean on board diagnostic
requirement.
JA - Indicates test vehicle meets
Japanese on board diag-
nostic requirement.
OUTSID AIR (- 40 – 215ºC) or (- 40 –
419ºF)
Outside Air Temperature gives tempera-
ture outside.
PTO STATUS (OFF or ON)
Power Take Off Status allows module to
keep track of Power at Take-Off.
REL FRP (0 – 5177.27 kPa) or (0 – 750.
psi)
Relative Fuel Rail Pressure (Vacuum) is
the fuel rail pressure at engine.
REL TPS (0 – 100%)
Relative Throttle Position is the normal-
ized relative throttle position.
SECOND AIR (AIR_STAT: UPS, DNS or
OFF)
Commanded Secondary Air Status is on
newer vehicles and actuators to control
pollution control.
