2. Control System
*SFI system
The SFI system monitors the engine condition through the signals input from each sensors to the engine control module.
The control signal is sent to the engine control module TERMINALS #1, #2, #3, #4, #5, #6, #7, #8 to operate the injector
(Fuel injection). The SFI system controls the fuel injection by the engine control module in response to the driving
conditions.
*ESA system
The ESA system monitors the engine condition through the signals input from each sensors to the engine control module.
The best ignition timing is decided according to this data and the data memorized in the engine control module. The
control signal is output to TERMINALS IGT1, IGT2, IGT3, IGT4, IGT5, IGT6, IGT7, IGT8, and these signals control the
igniter to provide the best ignition timing.
*Heated oxygen sensor heater control system
The heated oxygen sensor heater control system turns the heater on when the intake air volume is low (Temp. of exhaust
emission is low), and warms up the heated oxygen sensors to improve their detection performance. The engine control
module evaluates the signals from each sensors, and outputs current to TERMINALS HT1A, HT1B, HT2A, HT2B to
control the heater.
*Fuel pump control system
The engine control module supplies current to TERMINAL FPR, and controls the operation speed of the fuel pump by the
F/PUMP relay.
*ACIS
The ACIS includes a valve in the bulkhead separating the surge tank into two parts. This valve is opened and closed in
accordance with the driving conditions to control the intake manifold length in two stages, for increased engine output in all
ranges from low to high speeds.
*ETCS-i
The ETCS-i controls the engine output at its optimal level in accordance with the opening of the accelerator pedal, under
all driving conditions.
3. Diagnosis System
When there is a malfunction in the engine control module signal system, the malfunctioning system is recorded in the
memory. The malfunctioning system can be found by reading the code displayed on the malfunction indicator lamp.
4. Fail-Safe System
When a malfunction has occurred in any system, there is a possibility of causing engine trouble due to continued control
based on that system. In that case, the fail-safe system either controls the system using the data (Standard values)
recorded in the engine control module memory, or else stops the engine.

REPLACEMENT
CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Care should be taken, therefore, when changing en-
gine oil to minimize the frequency and length of time
your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil
should be worn. The skin should be thoroughly
washed with soap and water, or use water-less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filters must be disposed of only at desig-
nated disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the 2 nuts and engine under cover No.3.
(b) Remove the oil filler cap.
(c) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Remove the 2 bolts and service hole cover.

not to drop any oil on the contact surfaces of the oil pump
and cylinder block.

the old packing (FIPG) material from the gasket sur-
faces and sealing groove.

Thoroughly clean all components to remove all the
loose material.

Using a non-residue solvent, clean both sealing
surfaces.
(b) Apply seal packing to the oil pump as shown in the illustra-
tion.
Seal packing: Part No. 08826-00080 or equivalent
NOTICE:
Avoid applying an excessive amount to the surface. Be par-
ticularly careful near oil passage.

Install a nozzle that has been cut to a 2 - 3 mm (0.08
- 0.12 in.) opening.

plication. Otherwise the material must be removed
and reapplied.

stall cap.
(c) Install a new O-ring to the cylinder block.
(d) Engage the spline teeth of the oil pump drive gear with the
large teeth of the crankshaft, and slide the oil pump on the
crankshaft.
(e) Install the oil pump with the 8 bolts. Uniformly tighten the
