ELECTRONIC CONTROL SYSTEM
The CAMRY 5S±FE engine is equipped with a TOYOTA Computer Controlled System (TCCS)
which centrally controls the MFI/SFI, ESA, IAC diagnosis systems etc. by means of an Engine
Control Module (ECM±formerly MFI/SFI computer) employing a microcomputer.
The ECM controls the following functions:
1. Multiport Fuel Injection (MFI)/Sequential Multiport Fuel Injection (SFI)
The ECM receives signals from various sensors indicating changing engine operation conditions
such as:
Intake manifold pressure
Intake air temperature
Engine coolant temperature
Engine speed
Throttle valve opening angle
Exhaust oxygen content etc.
The signals are utilized by the ECM to determine the injection duration necessary for an optimum
air±fuel ratio.
2. Electronic Spark Advance (ESA)
The ECM is programmed with data for optimum ignition timing under all operating conditions.
Using data provided by sensors which monitor various engine functions (RPM, engine coolant
temperature, etc.), the microcomputer (ECM) triggers the spark at precisely the right instant.
3. Idle Air Control (IAC)
The ECM is programmed with target idling speed values to respond to different engine conditions
(engine coolant temperature, air conditioning ON/OFF, etc.). Sensors transmit signals to the ECM
which controls the flow of air through the bypass of the throttle valve and adjusts idle speed to
the target value.
4. Diagnosis
The ECM detects any malfunctions and abnormalities in the sensor network and lights a
malfunction indicator lamp in the combination meter. At the same time, trouble is identified and
a diagnostic trouble code is recorded by the EC
5. The diagnostic trouble code can be read by the
number of blinks of the malfunction indicator lamp when terminals TE1 and E1 are connected.
The diagnostic trouble codes are referred to in later page. (See page EG1±300)
Fail±Safe Function
In the event of the sensor malfunction, a back±up circuit will take over to provide minimal
driveability, and the malfunction indicator lamp will illuminate. The MFI (Multiport Fuel Injection)/SFI (Sequential Multiport Fuel Injection) system is composed
of 3 basic sub±systems: Fuel, Air Induction and Electronic Control Systems.
FUEL SYSTEM
Fuel is supplied under constant pressure to the MFI/SFI injectors by an electric fuel pump. The
injectors inject a metered quantity of fuel into the intake port in accordance with signals from the
ECM (Engine Control Module).
AIR INDUCTION SYSTEM
The air induction system provides sufficient air for engine operation.
± 5S±FE ENGINEMFI/SFI SYSTEMEG1±166

ELECTRONIC CONTROL SYSTEM
1. Before removing MFI/SFI wiring connectors, termi±
nals, etc., first disconnect the power by either turning
the ignition switch OFF or disconnecting the battery
terminals.
HINT: Always check the diagnostic trouble code
before disconnecting the negative (±) terminal cable
from the battery.
2. When installing the battery, be especially careful not
to incorrectly connect the positive (+) and negative
(±) cables.
3. Do not permit parts to receive a severe impact during
removal or installation. Handle all MFI/SFI parts care±
fully, especially the ECM.
4. Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal
contact can further troubles.
5. Do not open the ECM cover.
6. When inspecting during rainy weather, take care to
prevent entry of water. Also, when washing the
engine compartment, prevent water from getting on
the MFI/SFI parts and wiring connectors.
7. Parts should be replaced as an assembly.
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the
air induction system between the throttle body and
cylinder head will allow air suction and cause the
engine to run out of tune.
IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communica±
tion system, refer to the precaution in the IN section.

2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between
the terminals.
Resistance:
Approx. 13.8

If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.
ON±VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(a) With the engine running or cranking, use a sound
scope to check that there is normal operating noise in
proportion to engine speed.
(b) If you have no sound scope, you can check the injec±
tor transmission operation with your finger.
If no sound or unusual sound is heard, check the
wiring connector, injector or injection signal from the
ECM.

(b) Using SST, connect terminals TE1 and E1 of the data
link connector 1.

(c) Maintain engine speed in the range between 900 ±
1,300 rpm for 5 seconds. Check that it returns to idle
speed.
If the engine speed operation is not as specified,
check the IAC valve, wiring and ECM.

RADIATOR
The radiator performs the function of cooling the coolant which has passed through the water
jacket and become hot, and it is mounted in the front of the vehicle. The radiator consists of an
upper tank and lower tank, and a core which connects the two tanks. The upper tank contains the
inlet for coolant from the water jacket and the filler inlet. It also has a hose attached through
which excess coolant or steam can flow. The lower tank has an outlet and drain cock for the
coolant. The core contains many tubes through which coolant flows from the upper tank to the
lower tank as well as to cooling fins which radiate heat away from the coolant in the tubes. The
air sucked through the radiator by the electric fan, as well as the wind generated by the vehicle's
travel, passes through the radiator, cooling the coolant. Models with automatic transmission
include an automatic transmission fluid cooler built into the lower tank of the radiator. A fan with
an electric motor is mounted behind the radiator to assist the flow of air through the radiator. The
fan operates when the engine coolant temperature becomes high in order to prevent it from be-
coming too high.
RADIATOR CAP
The radiator cap is a pressure type cap which seals the radiator, resulting in pressurization of the
radiator as the coolant expands. The pressurization prevents the coolant from boiling even when
the engine coolant temperature exceeds 100°C (212°F). A relief valve (pressurization valve) and a
vacuum valve (negative pressure valve) are built into the radiator cap. The relief valve opens and
lets steam escape through the overflow pipe when the pressure generated inside the cooling sys-
tem exceeds the limit (coolant temperature: 110±120°C (230±248°F), pressure; 58.8103.0 kpa
(0.6±1.05 kgf/cm
2, 8.5±14.9 psi). The vacuum valve opens to alleviate the vacuum which develops
in the cooling system after the engine is stopped and the engine coolant temperature drops. The
valve's opening allows the coolant in the reservoir tank to return to the cooling system.
RESERVOIR TANK
The reservoir tank is used to catch coolant which overflows from the cooling system as a result
of volumetric expansion when the coolant is heated. The coolant in the reservoir tank returns to
the radiator when the coolant temperature drops, thus keeping the radiator full at all times and
avoiding needless coolant loss.
Check the reservoir tank level to learn if the coolant needs to be replenished.
WATER PUMP
The water pump is used for forced circulation of coolant through the cooling system. It is
mounted on the front of the cylinder block and driven by a timing belt.
THERMOSTAT
The thermostat has a wax type bypass valve and is mounted in the water inlet housing. The
thermostat includes a type of automatic valve operated by fluctuations in the engine coolant
temperature. This valve closes when the engine coolant temperature drops, preventing the
circulation of coolant through the engine and thus permitting the engine to warm up rapidly. The
valve opens when the engine coolant temperature has risen, allowing the circulation of coolant.
Wax inside the thermostat expands when heated and contracts when cooled. Heating the wax
thus generates pressure which overpowers the force of the spring which keeps the valve closed,
thus opening the valve. When the wax cools, its contraction allows the force of the spring to take
effect once more, closing the valve. The thermostat in this engine operates at a temperature of
82
C (180
F).
