Engine General Information and Diagnosis: 1A-28
OXYGEN SENSOR B1 S1 (HEATED OXYGEN
SENSOR-1, V)
It indicates output voltage of HO2S-1 installed on
exhaust manifold (pre-catalyst).
OXYGEN SENSOR B1 S2 (HEATED OXYGEN
SENSOR-2, V)
It indicates output voltage of HO2S-2 installed on
exhaust pipe (post-catalyst). It is used to detect catalyst
deterioration.
DESIRED IDLE (DESIRED IDLE SPEED, rpm)
The Desired Idle Speed is an ECM internal parameter
which indicates the ECM requested idle. If the engine is
not running, this number is not valid.
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.
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.
FUEL TANK LEVEL (%)
This parameter indicates approximate fuel level in the
fuel tank. As the detectable range of the fuel level sensor
is set as 0 to 100%, however, with some models whose
fuel tank capacity is smaller, the indicated fuel level may
be only 70% even when the fuel tank is full.
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.
STEP EGR FLOW DUTY (%)
This parameter indicates opening rate of EGR valve
which controls the amount of EGR flow.
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.
