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.
