CONTROL OXYGEN SENSOR

1. General information

The ECM applies 450 mV of the reference voltage to the O2 sensor. The ECM compares the reference voltage with the one generated by the O2 sensor.

The generated voltage is proportional to the difference of the amount of oxygen between in the ambient air and in the exhaust gas.

The atmosphere contains about 21 percent of oxygen. The exhaust gas of rich mixture contains almost zero oxygen. If the difference of the amount of

oxygen between the two sides, the ambient side and the exhaust gas side, is bigger, the sensor generates higher voltage.

When the exhaust gas is rich (below 14.7:1), the voltage output is high, above 450

mV.

When it is lean (above 14.7:1), the voltage output is low, below 450 mV.

The ECM uses Oxygen sensor information for:

CONTROLINTAKE AIR TEMPERATURE SENSOR

Intake Air Temperature(IAT) sensor

2. Description

The IAT sensor is a two-wire sensor positioned on the engine elbow hose to

measure the temperature of incoming air.

The IAT sensor is a kind of thermistor which provides a varying voltage signal

to the ECM depending on the resistance of itself. Its resistance decreases as

temperature increases. The ECM supplies a 5 volt signal to the IAT through

a dropping resistor. Sensor resistance and resulting sensor voltage become hi

gh together when the sensor is cold. As temperature rises, the resistance an

d voltage go down.

Air temperature readings are of particular importance during the cold engine

operation in open loop. A reading of the manifold or the intake air temperatur

e is needed by the ECM to :

Adjust the A/F ratio in accordance with air density, particularly during the cold

engine operation when the exhaust manifold and fuel are below normal

operating temperature.

Regulate spark advance and acceleration enrichment.

Determine when to enable the EGR and CCCP and so on.(some applications)

CONTROLMANIFOLD ABSOLUTE PRESSURE

SENSOR

MAP Sensor1. Description

The MAP sensor is a three - wire sensor. It is located on the intake manifold and

connected directly to intake manifold pressure (vacuum).

The MAP sensor measures changes in intake manifold air pressure. The ECM

uses this information from the MAP to calculate fuel and spark timing.

The Manifold absolute pressure is exactly opposite to manifold vacuum. Therefor

e, the MAP is low when vacuum is high (e.g. at closed throttle). When the engine is

not running, the manifold is under atmospheric pressure and the MAP sensor is

registering barometric (BARO) pressure.

The BARO pressure reading is used during engine start-up for fuel delivery

calculations as well as during engine running for fuel and spark calculations.

The ECM updates its BARO pressure reading when the ignition is cycled and

when the TP is at wide open.

The ECM uses MAP information for :

CMP(Camshaft position) sensor1. Description

The camshaft position(CMP) sensor sends signals to the ECM. The ECM uses this

signal as a “synchronous pulse” to trigger the injectors in the proper sequence. The ECM uses these signals to indicate the position of #1 piston during its powerstroke. This allows the ECM to calculate true sequential fuel injection mode of operation.

If the ECM detects an incorrect CMP sensor signal while the engine is running, DTC will be set. If CMP sensor signals are lost while the engine is running, the fuel injection system will shift to a calculated sequential fuel injection mode based on the last fuel injection pulse,and the engine will continue to run.

CONTROL KNOCK SENSOR

Knock sensor1. Description

The knock sensor is used to detect engine detonation, allowing the ECM to retard

ignition control spark timing based on the knock sensor signal. The knock sensor

produces AC signals. The amplitude and frequency of the knock sensor signal depen

d upon the amount of knock being experienced.

The ECM contains a non-replaceable knock filter module called a signal-to-noise

enhancement filter module. This filter module in the ECM determine whether knock is

occurring by comparing the signal level on the knock sensor circuit with the voltage level

on the noise channel.

The noise channel allows the ECM to reject any false knock signal by recognizing

normal engine mechanical noise. Normal engine noise varies depending on engine

speed and load. When the ECM determines that an abnormally low noise channel voltag

e level is being experienced, DTC(s) will be set.

CONTROL COMMUNICATION (IEFI-6, ITMS-6F)

Communication between ECM & TCMThe ECM and the TCM share the data ; Engine rpm, P/N position, Throttle position, Engine

torque, Vehicle speed. With these data the TCM can determine the proper shifting timing and

the ECM reduces engine torque by retarding ignition angle briefly in order to protect the shift

elements of the automatic transaxle from excessive thermal stress during shifting.

The way the IEFI-6 (ITMS-6F) ECM communicates with the TCM is the discrete signal lines.

Dual Coil Pack(DCP) (MR 140)

1. Description

The MR 140 ECM uses the DCP ignition system, which is more developed one

compared to the DIS system. DIS(Direct Ignition System) has been used for

Daewoo cars such as T-100, J-100, V-100. Unlike the DIS of which coil

driver is integrated in the DIS module, the DCP has its coil driver inside the

ECM so that it becomes more compact and reliable.

After the CKP or RPM signals are transferred to the ECM, the coil driver controls

the primary coil to generate high voltage at the secondary coil.

CONTROLEXHAUST GAS RECIRCULATION

(ITMS-6F)

Exhaust Gas Recirculation (EGR)

1. Type : Back pressure type

The EGR valve restricts NOx generation by recirculating some amount of the exhaust gas into the combustion chamber to reduce the combustion

temperature.

The recirculated gas results in reduced charging efficiency of mixture so that the engine performance drops down. Because of this fact, EGR valve is tuned to

operate in the area where oxidized substances are generated much. The way it operates is that after the vacuum bleed valve is closed by the exhaust-gas pressure, the valve is opened by the vacuum in the manifold upon the upside of the diaphragm, which makes the gas is recirculated.

Throttle body

Throttle valve

Intake air

Pintle

1. Description

The IAC valve is located in the throttle body. It has a movable pintle at the one en

d , driven by a small electric motor called a stepping motor. The stepping motor is

capable of moving in exact, measured amounts called steps.

The ECM uses the IAC valve to control idle rpm. It performs this function by

changing the pintle position in the idle air passage of the throttle body. This v

aries the air flow around the throttle plate when the throttle is closed.

During closed throttle, the ECM continuously compares actual idle rpm with the

programmed desired idle rpm and adjusts the IAC valve accordingly to achieve

the desired idle rpm. In some applications, the ECM also adjusts ignition timing to

control idle speed even more precisely.

To determine the desired position of the IAC pintle during idle or deceleration,

which is indicated by closed throttle position (0% throttle angle), the ECM refers

to the following inputs:

Battery voltage

ECT

TP sensor

Engine load (MAP, A/C compressor)

CONTROLCONTROLLED CHARCOAL CANISTER

PURGE SOLENOID

Controlled Charcoal Canister Purge (CCCP) solenoid

1. Description

The basic evaporative emission (EVAP) control uses the charcoal canister storage method. This method transfers fuel vapor from the fuel tank to the activated

carbon (charcoal) storage canister which holds the vapors when the vehicle is not operating. When the engine is running, the fuel vapor is purged from the carbon element by intake airflow and consumed in the normal combustion process.

Gasoline vapor from the fuel tank flow into the tube labeled tank. These vapors are

absorbed into the carbon. The canister is purged by the ECM when the engine has been running for a specific amount of time. Air is drawn into the canister and mixed with the vapor. This mixture is then drawn into the intake manifold.

The ECM supplies a ground to energize the controlled canister purge solenoid valve. This valve is PWM controlled. The purge PWM duty cycle varies accor

ding to operating conditions determined by mass airflow, fuel trim,and intake air temperature.

Poor idle ,stalling, and poor drive-ability can be caused by the following conditions:• Inoperative CCCP valve• Damaged canister• Hose are split, cracked, or not connected to the proper tubes.
