The exhaust manifolds adopt a double-wall construction consisting of
stainless steel pipes to improve the warm-up performance of the TWC.

4-hole type fuel injectors have been adopted to improve the atomization
of fuel.*

4. Intake and Exhaust System (California Specification Automatic Transaxle Model)
Exhaust Manifold
The exhaust manifolds have been changed from the previous 3-layer type, in which ceramic wool is sand-
wiched, to the double-wall construction consisting of stainless steel pipes. As a result, the warm-up per-
formance of the TWC has been improved.
The left bank exhaust manifold integrates with a WU-TWC.

6. Engine Control System
General
The California specification automatic transaxle model has adopted an air-fuel sensor. All models are avail-
able with the Engine Immobiliser System as an optional equipment. The models other than the California
specification automatic transaxle model are basically the same as the '97 models except for the adoption
of the Engine Immobiliser System.
SFI (Sequential Multiport Fuel Injection)
The precision of the air-fuel ratio feedback control has been improved through the adoption of the air-fuel
ratio sensor. The operation of the air-fuel ratio sensor and the ECM are the same as those of the California
specification model with the 5S-FE engine and automatic transaxle. For details, see the '97 Camry New Car
Features (Pub. No. NCF134U).
Engine Immobiliser System
The engine immobiliser system has been designed to prevent the vehicle from being stolen. This system
uses an ECM that stores the ID code of the authorized ignition key. If an attempt is made to start the engine
using an unauthorized key, the ECM prohibits fuel delivery and ignition effectively disabling the engine.
For details, see page 23 in the Engine Immobiliser system section.

Be sure that the ignition is off if
you work near the electric cooling
fans or radiator grille. With the
ignition on, the electric cooling fans
will automatically start to run if the
engine coolant temperature is high
and/or the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move used engine oil from your
skin, wash thoroughly with soap
and water.
Do not leave used oil within the
reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers or
onto the ground. Call your dealer or
a service station for information
concerning recycling or disposal.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
Add only demineralized or distilled
water to fill the radiator. And if you
spill some of the coolant, be sure
to wash off with water to prevent it
from damaging the parts or paint.
Do not allow dirt or anything else
to fall through the spark plugholes.
Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not reuse platinum±tipped spark
plugs by cleaning or regapping.
Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.

FUEL SYSTEM
1. General
The compressed gas [maximum pressure approximately 250 kg/cm2 (3600 psi, 24.8 MPa) @215C (705F)]
from the CNG fuel tank located in the rear section of the vehicle is routed via a fuel filter to the engine
compartment. The pressure of the fuel is then reduced to 8 kg/cm
2 (114 psi, 785 kPa).
A pressure regulator and injectors designed exclusively for CNG application have been adopted.
A fuel pressure sensor and a fuel temperature sensor that are used for the correction of the fuel injection
volume are located on the delivery pipe.
The fuel tank, pressure regulator, and the delivery pipe are provided with shutoff valves that shut off
the fuel when the ignition switch is turned OFF.
In addition, these valves shut off the fuel when the engine stalls, the SRS airbag is deployed, or the
pressure in the main pipe becomes abnormally low.
A fuel temperature sensor for the fuel gauge is mounted on the tank valve assembly, and a fuel pressure
sensor is mounted immediately upstream of the pressure regulator.
