REMOVAL SERVICE POINTS
 A DRIVE BELT REMOVAL
(1) Align the hole in the auto tensioner bracket with that in the arm and insert a screwdriver into the holes.
(2) Remove the drive belt.
 B POWER STEERING OIL PUMP REMOVAL
Remove the power steering oil pump from the bracket with
the hose attached.
NOTE
Place the removed power steering oil pump in a place where
it will not be a hindrance when removing and installing the
engine assembly, and tie it with a cord.
 C A/C COMPRESSOR REMOVAL
Disconnect the A/C compressor connector and remove the
compressor from the compressor bracket with the hose still
attached.
NOTE
Place the removed A/C compressor where it will not be a
hindrance when removing and installing the engine assembly,
and tie it with a cord.
 D ENGINE MOUNT BRACKET REMOVAL
(1) Support the engine with a garage jack.
(2) Remove the special tools which was attached when the transmission assembly was removed.
(3) Hold the engine assembly with a chain block or similar tool.
(4) Place a garage jack against the engine oil pan with a piece of wood in between, jack up the engine so that
the weight of the engine is no longer being applied to
the engine mount bracket, and then remove the engine
mount bracket.

E ENGINE ASSEMBLY REMOVAL
After checking that all cables, hoses and harness connectors,
etc., are disconnected from the engine, lift the chain block
slowly to remove the engine assembly upward from the engine
compartment.
INSTALLATION SERVICE POINTS
 A ENGINE ASSEMBLY INSTALLATION
Install the engine assembly, checking that the cables, hoses,
and harness connectors are not clamped.
 B ENGINE MOUNT BRACKET INSTALLATION
(1) Place a garage jack against the engine oil pan with a piece of wood in between, and install the engine mount
bracket while adjusting the position of the engine.
(2) Support the engine with the garage jack.
(3) Remove the chain block and support the engine assembly
with the special tools.
 C HIGH-PRESSURE FUEL HOSE INSTALLATION
(1) Apply a small amount of new engine oil to the O-ring, then fit the O-ring in the delivery pipe.
Caution
Do not let any engine oil get into the delivery pipe.
(2) Check that the high pressure hose turns smoothly. If the hose does not turn smoothly, the O-ring is probably
being clamped. Disconnect the high-pressure fuel hose
and check the O-ring for damage. After this, re-install
the hose to the delivery pipe and check that the hose
turns smoothly.
(3) Tighten the mounting bolt to the specification.

Given above is the MPI system diagram for EVOLUTION-IV. The MPI system for EVOLUTION-V is different
from this in the following point;
Oxygen sensor with a heater is adopted.
The diagnosis connector power supply circuit is different.
The high temperature sensor is no longer used.

TROUBLESHOOTING
1. DIAGNOSIS FUNCTION
1-1 ENGINE WARNING LAMP (CHECK ENGINE LAMP)
If an abnormality occurs in any of the following items related
to the Multipoint Fuel Injection (MPI) system, the engine
warning lamp will illuminate.
If the lamp remains illuminated or if the lamp illuminates while
the engine is running, check the diagnosis code output.
Engine warning lamp inspection items
Engine-ECU
Air flow sensor (AFS)
Intake air temperature sensor
Throttle position sensor (TPS)
Engine coolant temperature sensor
Crank angle sensor
Camshaft position sensor
Barometric pressure sensor
Detonation sensor
Injector
Ignition coil, power transister
Misfire
1-2 METHOD OF READING AND ERASING DIAGNOSIS
CODES
(1) Use the special tool to earth No.1 terminal (diagnosis
control terminal) of the diagnosis connector.
(2) To check ABS system, remove the valve relay.
NOTE
That is because the valve relay is off and the warning
lamp remains illuminated if there is a fault in the ABS
system.
(3) Turn off the ignition switch.
(4) Read out a diagnosis code by observing how the warning
lamp flashes.

1-3 ERASING DIAGNOSIS CODES
(1) Turn the ignition switch to OFF.
(2) After disconnecting the battery cable from the battery (–) terminal for 10 seconds or more, reconnect
the cable.
(3) After the engine has warmed up, run it at idle for about 15 minutes.
1-4 FAIL-SAFE FUNCTION REFERENCE TABLE
When the main sensor malfunctions are detected by the diagnosis function, the vehicle is controlled
by means of the pre-set control logic to maintain safe conditions for driving.
Malfunctioning itemControl contents during malfunction
Air flow sensor (AFS)(1) Uses the throttle position sensor signal and engine speed signal (crank angle sensor
signal) to take reading of the basic injector drive time and basic ignition timing from
the pre-set mapping.
(2) Fixes the ISC servo in the appointed position so idle control is not performed.
Intake air temperature
sensorControls as if the intake air temperature is 25C.
Throttle position
sensor (TPS)No increase in fuel injection amount during acceleration due to the throttle position sensor
signal.
Engine coolant
temperature sensorControls as if the engine coolant temperature is 80C.
(This condition is maintained until the ignition switch is turned off even when the sensor signal
returns normal.)
Camshaft position
sensor(1) Injects fuel to all cylinders simultaneously for 4 seconds.
(However, after the ignition switch is turned to ON, the No. 1 cylinder top dead centre
is not detected at all.)
(2) Lets the fan motor (radiator and condensor) run at high speed.
Barometric pressure
sensorControls as if the barometric pressure is 101 kPa {760 mmHg}.
Detonation sensorSwitches the ignition timing from ignition timing for super petrol to ignition timing for standard
petrol.
Ignition coil, power
transistorCuts off the fuel supply to cylinders with an abnormal ignition.
Alternator FR terminalDoes not control the output of the alternator according to an electrical load. (works as a
normal alternator)
Misfire
(Evolution-V only)Cuts off the fuel to the misfiring cylinder if a misfire that could damage the catalyst is detected.
