CANIST PRG DUTY (EVAP CANISTER PURGE FLOW
DUTY, %)
This parameter indicates valve ON (valve open) time
rate within a certain set cycle of EVAP canister purge
valve which controls the amount of EVAP purge.

FOR NO.1 CYLINDER, °)
Ignition timing of No.1 cylinder is commanded by ECM.
The actual ignition timing should be checked by using
the timing light.
EGR VALVE OPENING (%)
This parameter indicates opening rate of EGR valve
which controls the amount of EGR flow.
VVT GAP (TARGET-ACTUAL POSITION, °) (VVT
model)
It is calculated using the formula: target valve timing
advance – actual valve timing advance.

ON is displayed when ECM activates the fuel pump via
the fuel pump relay switch.
STARTER SW (STARTER SWITCH, ON/OFF)
This parameter indicates condition of starting motor relay
output.

CONTROL RELAY, ON/OFF)
ON: Command for A/C condenser cooling fan control
relay operation being output.
OFF: Command for relay operation not being output.
TP SENSOR 1 VOLT (THROTTLE POSITION SENSOR
(MAIN) OUTPUT VOLTAGE, V)
The Throttle Position Sensor (Main) reading provides
throttle valve opening information in the form of voltage.
TP SENSOR 2 VOLT (THROTTLE POSITION SENSOR
(SUB) OUTPUT VOLTAGE, V)
The Throttle Position Sensor (Sub) reading provides
throttle valve opening information in the form of voltage.
APP SENSOR 1 VOLT (ACCELERATOR PEDAL
POSITION (APP) SENSOR (MAIN) OUTPUT
VOLTAGE, V)
The Accelerator Pedal Position (APP) Sensor (Main)
reading provides accelerator pedal opening information
in the form of voltage.
APP SENSOR 2 VOLT (ACCELERATOR PEDAL
POSITION (APP) SENSOR (SUB) OUTPUT VOLTAGE,
V)
The Accelerator Pedal Position (APP) Sensor (Sub)
reading provides accelerator pedal opening information
in the form of voltage.
ACCEL POSITION (RELATIVE ACCELERATOR
PEDAL POSITION, %)
When accelerator pedal is at fully released position,
accelerator pedal is indicated as 0 – 3% and 90 – 100%
fully depressed position.
TARGET THROTTLE POSI (TARGET THROTTLE
VALVE POSITION, %)
Target Throttle Valve Position is ECM internal parameter
which indicates the ECM requested throttle valve
position.
IAC THROTTLE OPENING (IDLE AIR (SPEED)
CONTROL THROTTLE VALVE OPENING, %)
This parameter indicates throttle valve opening of idle air
control in %.
(100% indicates the maximum idle air flow.)
THROTTLE MOTOR VOLT (V)
This parameter indicates power supply voltage of throttle
actuator (motor) control circuit (input voltage from
throttle actuator control relay).
CLOSED THROTTLE POS (CLOSED THROTTLE
POSITION, ON/OFF)
This parameter reads ON when throttle valve is fully
closed, or OFF when it is not fully closed.

9Check wire circuit
1) Install “A/C” fuse “20 A” to individual circuit fuse box
No.1.
2) Connect A/C condenser cooling fan control relay to
individual circuit fuse box No.1 with ignition switch turn
OFF.
3) Start engine then turn ON A/C switch and blower motor
switch.
4) Measure voltage between engine ground and “RED”
wire terminal in A/C condenser fan harness connector.
Is voltage 10 – 14 V?Go to Step 10. Open wire in “RED”
circuit.
10Check wire circuit
1) Disconnect connector from A/C condenser cooling fan
with ignition switch turned OFF.
2) Measure resistance between “BLK” wire terminal of A/C
condenser cooling fan connector and engine ground.
Is resistance below 1
Ω?Go to Step 11. Open or high resistance
wire in “BLK” circuit.
11Check A/C condenser cooling fan
1) Check A/C condenser cooling fan operates referring to
“Condenser Cooling Fan Inspection in Section 7B”.
Is it good condition?Substitute a known-
good ECM and recheck.Faulty A/C condenser
cooling fan. Step Action Yes No
