4. OPEN2:The PCM is operating in Open Loop control strategy due to detected system fault.
Certain actuator or sensor faults will cause module to use an open loop strategy.
5. CLSD1:Closed Loop control is current 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 calculations.
IAT TEMP (-40 - 215°C) or (-40 - 419°F)
Intake Air Temperature is a measure of intake air temperature to determine correct air/fuel ratios
and spark timing operations.
IGN ADV (-64 - 63.5°)
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 mixture adjustment. The mixture can range, with midpoint being 0.
NOTE: Positive reading indicates module commanded a long-term rich mixture
correction in response to a lean operating condition. A negative 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 - 86.5lb/min)
Air Flow Rate from Mass Air Flow Sensor to module indicating mass of air entering engine.
MAP (0 - 255kPa) or (Hg)
Intake Manifold Absolute Pressure displays manifold pressure.
MIL DIST (0 - 65535km) or (0 - 40,722miles)
Distance Traveled while Malfunction Indicator Lamp is Active is a counter that displays distance
traveled since “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 - 65535min) or (0 - 1092.25Hrs)
Distance Since Monitor Status Data Trouble Code is the distance traveled since “Check Engine or
Service Engine Soon” light came on.
O2Sxy (0 - 1.275V)
Oxygen Sensor Output Voltage is the voltage generated from the oxygen sensor to increase and
decrease the amount of exhaust gas.
O2Sxy (-128 - 127.996mA)
Oxygen Sensor Output is used for linear or wide ratio oxygen sensors to increase and decrease
the amount of exhaust gas
OBD2 STAT (OBD II, OBDI, OBD, NOT OBD, EOBD and/or JOBD)
On Board Diagnostic shows what vehicle was made for.
Data Parameters:
OBD II - Indicates vehicle meets California OBD ARB requirements
OBD I - Indicates vehicle does not meet OBDII requirements.
OBD - Indicates vehicle meets Federal EPA requirements.
NOT OBD - Indicates vehicle is not on board diagnostic compliant.
EOBD - Indicates vehicle meets European on board diagnostic requirement.
JOBD - Indicates vehicle meets Japanese on board diagnostic requirment.
OUTSID AIR (-40 - 215°C) or (-40 - 419°F)
Outside Air Temperature gives temperature outside.
PTO STATUS (OFF or ON)
Power Take Off Status allows module to keep track of Power at Take-Off.
REL FRP (0 - 5177.27kPa) or (750.9PSI)
Realative Fuel Rail Pressure (Vacuum) is the fuel rail pressure at engine.
