INSPECTION
FUNCTION AND OPERATION PRICIPLE
Based on information from various sensors, the PCM measures the fuel injection amount. The fuel injector is a
solenoid- operated valve and the fuel injection amount is controlled by length of time that the fuel injector is held open.
The PCM controls each injector by grounding the control circuit. When the PCM energizes the injector by grounding
the control circuit, the circuit voltage should be low (theoretically 0V) and the fuel is injected. When the PCM de-
energizes the injector by opening control circuit, the fuel injector is closed and circuit voltage should momentarily peak.
If an injector connector is disconnected for more than 46 seconds while the engine runs, the PCM will determine
that the cylinder is misfiring and cut fuel supply. So be careful not to exceed 46 seconds. But the engine runs
normally in 10 seconds after turning the ignition key off.

MODE 1FORCED ENGINE
SHUTDOWN Engine stop algorithm procedure
a. Fatal PCM internal programming error
b. Faulty intake system or throttle body
MODE 2 FORCED IDLE &
POWER
MANAGEMENT Forced idle state controlled by
fuel quantity regulation and
ignition timing adjustment a.
ETC system can't control engine power
via throttle device
b. Disabled throttle control or broken throttle
position information
MODE 3 FORCED IDLE Forced idle state and no response
for accelerator activation a.
No information about the accelerator
position
a. Malfuctioning APS 1 and 2, faulty A/D
converter or internal controller
MODE 4 LIMIT
PERFORMANCE & POWER
MANAGEMENT Engine power is determined by
accelerator position and idle
power requirement (Limited
vehicle running)
a.
ETC system can't securely control engine
power
MODE 5 LIMIT
PERFORMANCE a.
Engine power varies with
accelerator position, but driver
perceives lack of engine
power.
b. MIL ON (Normal vehicle
running) a.
Not reliable accelerator position signal or
bad maximum power generation
a. Faulty APS, ignition voltage or internal
controller
MODE 6 NORMALNormal
COMPONENT INSPECTION
1.Connect a scantool on Diagnoisis Link Connector (DLC).
2. Start engine and check output voltages of TPS 1 and 2 at C.T and W.O.T.
Condition Output Voltage (V)
TPS 1 TPS 2
C.T 0.25 ~ 0.9V Min. 4.0V
W.O.T Min. 4.0V 0.25 ~ 0.9V
3. Turn ignition switch OFF and disconnect the scantool from the DLC.
4. Disconnect ETC module connector and measure resistance between ETC module terminals 4 and 1 (TPS 1).
5. Measure resistance between ETC module terminals 7 and 6 (TPS 2).
Specification: Refer to SPECIFICATION.
ETC MOTOR
1.Disconnect ETC module connector and measure resistance between ETC module terminals 5 and 8.

Specification: Refer to SPECIFICATION.
ETC SYSTEM INITIALIZATION
1.Erase DTC(s) memorized in PCM with a scan tool.
2. Turn ignition switch off and wait for about 10 seconds.
3. Turn ignition switch on for more then 1 second. (At this time, the PCM records initial position of ETC motor on its
EEPROM).
