VVT (CAMSHAFT POSITION) GAP [TARGET-ACTUAL
POSITION] (°)
It is calculated using the formula: target valve timing
advance – actual valve timing advance.
TP SENSOR VOLT (THROTTLE POSITION SENSOR
OUTPUT VOLTAGE, V)
The Throttle Position Sensor reading provides throttle
valve opening information in the form of voltage.
INJ PULSE WIDTH (FUEL INJECTION PULSE WIDTH,
msec.)
This parameter indicates time of the injector drive (valve
opening) pulse which is output from ECM (but injector
drive time of NO.1 cylinder for multiport fuel injection).
IAC FLOW DUTY (IDLE AIR (SPEED) CONTROL
DUTY, %)
This parameter indicates current flow time rate within a
certain set cycle of IAC valve (valve opening rate) which
controls the amount of bypass air (idle speed).
TOTAL FUEL TRIM B1 (%)
The value of Total Fuel Trim is obtained by putting values
of Short Term Fuel Trim and Long Term Fuel Trim. This
value indicates how much correction is necessary to
keep the air / fuel mixture stoichiometrical.
BATTERY VOLTAGE (V)
This parameter indicates battery positive voltage
inputted from main relay to ECM.
CANIST PRG DUTY (EVAP CANISTER PURGE FLOW
DUTY, %)
This parameter indicates valve ON (valve open) time
rate within a certain set cycle of EVAP purge solenoid
valve which controls the amount of EVAP purge.
0% means that the purge valve is completely closed
while 100% is a fully open valve.
CLOSED THROT POS (CLOSED THROTTLE
POSITION ON/OFF)
This parameter will read ON when throttle valve is fully
closed, or OFF when the throttle is not fully closed.
FUEL CUT (ON/OFF)
ON: Fuel being cut (output signal to injector is stopped)
OFF: Fuel not being cut
RADIATOR FAN (RADIATOR FAN CONTROL RELAY,
ON/OFF)
ON: Command for radiator fan control relay operation
being output.
OFF: Command for relay operation not being output.
Engine General Information and Diagnosis:
ELECTRIC LOAD (ON/OFF)
ON: Headlight, small light or rear window defogger ON
signal inputted.
OFF: Above electric loads all turned OFF.
A/C SWITCH (ON/OFF)
ON: A/C switch and blower motor switch ON signal
inputted.
OFF: A/C switch or blower motor switch ON signal not
inputted.
BAROMETRIC PRESS (kPa, inHg)
This parameter represents a measurement of barometric
air pressure and is used for altitude correction of the fuel
injection quantity and IAC valve control.
FUEL PUMP (ON/OFF)
ON is displayed when the ECM activates the fuel pump
via the fuel pump relay switch.
BRAKE SW (ON/OFF)
This parameter indicates the state of the brake switch.
PNP SIGNAL (PARK / NEUTRAL POSITION SIGNAL,
P/N RANGE or D RANGE)
It is detected by signal from TCM.
D range: A/T is in "R", "D", "2" or "L" range.
P/N range: A/T is in "P" or "N" range or the above signal
is not inputted from TCM.
PSP SWITCH (POWER STEERING PRESSURE
SWITCH, ON/OFF)
ON: PSP switch detected P/S operation. (high PS
pressure)
OFF: PSP switch does not detected P/S operation.
A/C COND FAN (ON/OFF)
ON: Command for operation being output.
OFF: Command operation not being output.
A/C PRESSURE SW (ON/OFF)
ON: A/C pressure switch not detected insufficient
refrigerant amount.
OFF: A/C pressure switch detected insufficient
refrigerant amount.
BLOWER FAN (ON/OFF)
This parameter indicates the state of the blower fan
motor switch.
A/C MAG SWITCH (A/C COMPRESSOR RELAY, ON/
OFF)
This parameter indicates the state of the A/C switch.
