GENERAL INFORMATION

M11301000001USA0000010000

The Multiport Fuel Injection System consists of
sensors which detect the engine conditions, the
ENGINE CONTROL MODULE (ECM) which controls
the system based on signals from these sensors, and
actuators which operate under the control of the ECM.
The ECM carries out activities such as fuel injection
control, idle air control, and ignition timing control.
In addition, the ECM is equipped with several
diagnostic test modes which simplify troubleshooting
when a problem develops.

FUEL INJECTION CONTROL
The injector drive times and injection timing are
controlled so that the optimum air/fuel mixture is
supplied to the engine to correspond to the
continually-changing engine operation conditions.
A single injector is mounted at the intake port of each
cylinder. Fuel is sent under pressure from the fuel tank
to the fuel injectors by the fuel pump, with the pressure
being regulated by the fuel pressure regulator. The
regulated fuel is distributed to each of the injectors.
Fuel injection is normally carried out once for each
cylinder for every two rotations of the crankshaft.
The firing order is 1-2-3-4-5-6. Each cylinder has a
dedicated fuel injector. This is called multiport.
The ECM provides a richer air/fuel mixture by carrying
out "open-loop" control when the engine is cold or
operating under high load conditions in order to
maintain engine performance.In addition, when the
engine is under normal operating temperature after
warming-up, the ECM controls the air/fuel mixture by
using the heated oxygen sensor signal to carry out
"closed-loop" control. The closed-loop control
achieves the theoretical air/fuel mixture ratio where
the catalytic converter can obtain the maximum
cleaning performance.

THROTTLE VALVE OPENING CONTROL
This system electrically controls the opening of the
throttle valve. The ECM detects the amount of travel
of the accelerator pedal via the accelerator pedal
position sensor, and controls the actuation of the
throttle actuator control motor, which is mounted on
the throttle body, in order to attain the target throttle
valve opening that has been predetermined in
accordance with driving conditions.

IDLE AIR CONTROL
The idle speed is kept at the optimum speed by
controlling the amount of air that passes through the
throttle valve in accordance with changes in idling
conditions and engine load during idling.
The ECM drives the throttle actuator control motor to
keep the engine running at the pre-set idle target
speed in accordance with the engine coolant
temperature and A/C and other electrical load. In
addition, when the air conditioning switch is turned off
and on while the engine is idling, the throttle actuator
control motor adjusts the throttle valve pass-through
air amount according to the engine load conditions to
avoid fluctuations in the engine speed.

IGNITION TIMING CONTROL
The ignition power transistor located in the ignition
primary circuit turns ON and OFF to control the
primary current flow to the ignition coil. This controls
the ignition timing to provide the optimum ignition
timing with respect to the engine operating conditions.
The ignition timing is determined by the ECM from
engine speed, intake air volume, engine coolant
temperature, and atmospheric pressure.

DIAGNOSTIC TEST MODE

｠

When a fault is detected in one of the sensors or
actuators related to emission control, the
Malfunction Indicator Lamp (SERVICE ENGINE
SOON or Check Engine Lamp) illuminates to warn
the driver.

｠

When a fault is detected in one of the sensors or
actuators, a diagnostic trouble code corresponding
to the fault is stored in the ECM.

｠

The RAM data inside the ECM that is related to the
sensors and actuators can be read with the scan
tool. In addition, the actuators can be controlled by
scan tool MB991958 (M.U.T.-III sub assembly)
under certain circumstances.

OTHER CONTROL FUNCTIONS

Fuel Pump Control

｠

Turns the fuel pump relay ON so that current is
supplied to the fuel pump while the engine is
cranking or running.
