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- tions.

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- A 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.

UPS - UP STREAM module is de-
