NEW FEATURES Ð 5S-FNE ENGINE19
ENGINE CONTROL SYSTEM
1. General
An engine control system based on the 5S-FE engine has been adopted. The knock sensor has been discontin-
ued because natural gas has a high octane value and is less susceptible to knocking.
The engine control system of 5S-FNE and 5S-FE engines are compared below.
System
Outline5S-FNE5S-FE
SFI
Sequential
A D-type SFI system is used, which indirectly detects
intake air volume by manifold absolute pressure sensor.
Sequential
Multiport Fuel
Injection
The fuel injection system is a sequential multiport fuel
injection system.
Ignition timing is determined by the ECM based on sig-
nals from various sensors.
ESA
Electronic Spark
AdvanceThe ECM corrects the ignition timing in response to en-
gine knocking in accordance with the signals received
from the knock sensor.
Ð
Advance
Torque control correction during gear shifting had been
used to minimize the shift shock.*1
IAC
(Idle Air Control)A rotary solenoid type IAC valve controls the fast idle
and idle speeds.
(1-Coil Type
Built-in Driver)(2-Coil Type)
Fuel Pump ControlFuel pump operation is controlled by signal from the
ECM.Ð
Fuel Cut-Off
Control
The fuel shutoff valves for the fuel tank, fuel pressure
regulator, and delivery pipe are shut off to stop the sup-
ply of fuel when the ignition switch is turned OFF or
during abnormal conditions (such as engine stalling,
SRS airbag deployed, etc.).
Ð
Oxygen Sensor
and Air Fuel Ratio
Sensor
Heater ControlMaintains the temperature of the oxygen sensor and air
fuel ratio sensor at an appropriate level to increase accu-
racy of detection of the oxygen concentration in the ex-
haust gas.
*2
EGR Cut-Off
ControlCuts off EGR according to the engine condition to
maintain drivability of the vehicle and durability of the
EGR components.

Evaporative
Emission ControlThe ECM controls the purge flow of evaporative emis-
sions (HC) in the charcoal canister in accordance with
engine conditions.
Ð
Air Conditioning
Cut-Off ControlBy turning the air conditioning compressor ON or OFF
in accordance with the engine condition, drivability is
maintained.
*3*3
When the ECM detects a malfunction, the ECM diag-
noses and memorized the failed section.
DiagnosisThe diagnosis system includes a function that detects a
malfunction in the evaporative emission control sys-
tem.
Ð
Fail-Safe
When the ECM detects a malfunction, the ECM stops
or controls the engine according to the data already
stored in memory.

*1: Only for Automatic Transaxle Model
*
2: Air fuel ratio sensor only for California specification model.

3: The air conditioning magnet clutch controled by the ECM

SCHEDULED MAINTENANCE LOGS21 Brake Linings/Drums and Brake Pads/Discs
Check the brake linings (shoes) and drums for scoring, burning,
fluid leakage, broken parts and excessive wear. Check the pads for
excessive wear and the discs for runout, excessive wear and fluid
leakage. A qualified technician should perform these inspections.
Charcoal Canister (CA, MA and NY vehicles)
Check for internal damage and clogging. If necessary, clean
with compressed air or replace. A qualified technician should
perform these operations.
Differential Oil
Inspect each component for signs of leakage. If you discover any
leakage, have it repaired by a qualified technician immediately.
Drive Belts
Inspect for cracks, excessive wear and oiliness. Check the belt ten-
sion and adjust if necessary. Replace the belts if they are damaged.
Drive Shaft Boots
Check the drive shaft boots and clamps for cracks, deteriora-
tion and damage. Replace any damaged parts and, if necessary,
repack the grease. Selected models also require periodic inspec-
tion of the flange bolts for proper torque. A qualified technician
should perform these operations.
Engine Air Filter
Check for damage, excessive wear and oiliness. Replace if necessary.
Engine Coolant
Drain and flush the cooling system and refill with an ethylene-
glycol type coolant. A qualified technician should perform
this operation.
Engine Oil and Oil Filter
Change the oil filter and replace the engine oil with API SH,
Energy- Conserving II multigrade or ILSAC multigrade oil.
For recommended viscosity, refer to your
Owner’s Manual.

circuits, particularly the primary
ignition circuit, to become
operational.
RESISTOR, VARIABLE or RHEOSTAT
A controllable resistor with a variable
rate of resistance.
Also called a potentiometer or
rheostat.

and close a switch to create a signal
for activation of other components.TRANSISTOR
A solidstate device typically used as
an electronic relay; stops or passes
current depending on the voltage
applied at ºbaseº.

CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.

2. FILL ENGINE COOLANT
(a) Slowly fill the system with coolant.

Use of improper coolants may damage engine cool-
ing system.

Use ºToyota Long Life Coolantº or equivalent and
mix it with plan water according to the manufactur-
er's directions.

Using of coolant which includes more than 50 %
(freezing protection down to ±35°C (±31°F) or 60 %
