ment and deceleration enrichment.
OPEN2: T he 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.
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 calculatio
ns.
IAT TEMP (- 40 – 215ºC) or (- 40 – 419ºF)
Intake Air Temperature is a measure of intake air temperature to determine correct air/fuel
ratios and spark timing operations.
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 mixture adjustment. The mixture can range, with mid-
point being 0.
✓
Positive reading indicates module commanded a long-term rich mixture cor-
rection in response to a lean operating condition. A negative reading indicates
module has commanded a long-term lean mixture in response to a rich oper-
ating 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 displays manifold pressure.
MIL DIST (0 – 65,535 km) or (0 – 40,722 miles)
Distance Traveled while Malfunction Indicator Lamp is Active is a counter that displays dis-
tance 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 Trouble 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 voltage 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 diagnostic ARB requirements
OBD I - Indicates test vehicle does not meet OBDII requirements.
US - Indicates test vehicle meets Federal EPA requirements.
NONE - Indicates test vehicle is not on board diagnostic compliant.
EU - Indicates test vehicle meets European on board diagnostic requirement.
JA - Indicates test vehicle meets Japanese on board diagnostic requirement.
OUTSID AIR (- 40 – 215ºC) or (- 40 – 419ºF)
Outside Air Temperature gives temperature outside.
