Details
Intake and Exhaust
System
The intake system from the inlet duct to the throttle body has been
improved to increase torque and reduce noise.
A 2-way exhaust control system has been adopted on the TMMK made
model.
Fuel SystemAlong with the discontinuance of the air assist system, the fuel injectors and

For details, see the General 2000 Features section.
3. Intake and Exhaust System
Intake Air Line
An ejection pipe that protrudes into the air cleaner case has been added. Accordingly, the hybrid resonator
has been discontinued and a torque-up resonator has been added. Also, the shape of the inlet duct has been

6. Fuel System
General
The compressed gas [maximum pressure approximately 250 kg / cm
2 (3600 psi, 24.8 MPa) @ 21C
(70F)] 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 pres-
sure 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.

8. Engine Control System
General
An engine control system based on the 5S-FE engine has been adopted. The knock sensor has been discon-
tinued 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
Se
quential
A D-type SFI system is used, which indirectly detects
intake air volume by manifold absolute pressure sensor.Sequential
Multiport Fuel
InjectionThe fuel injection system is a sequential multiport fuel
injection system.
Ignition timing is determined by the ECM based on
signals from various sensors.
ESA
Electronic Spark
AdvanceThe ECM corrects the ignition timing in response to
engine knocking in accordance with the signals
received from the knock sensor.

dva ce
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
supply of fuel when the ignition switch is turned OFF or
during abnormal conditions (such as engine stalling,
SRS airbag deployed, etc.).
Ð
Injector ControlPrevents the frozen stuck of the injector to ensure the
startability of the engine at low temperature.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
accuracy of detection of the oxygen concentration in the
exhaust 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
emissions (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
Diagnosis
When the ECM detects a malfunction, the ECM
diagnoses and memorized the failed section.
DiagnosisThe diagnosis system includes a function that detects a
malfunction in the evaporative emission control system.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

CAMRY ± NEW FEATURES54
1MZ-FE ENGINE
The following items have been changed in the '00 CAMRY.
The system for detecting evaporative emission leaks has been changed.
For details, see the General 2000 Features section.
A thermostat monitor function has been newly provided. This function monitors the changes in the coolant
temperature at the time the engine is started, and if the coolant temperature does not reach a specified value
within a prescribed length of time, the thermostat is determined to be faulty.
AUTOMATIC TRANSAXLE
As in the 5S-FE engine model, the A140E automatic transaxle is used on the 5S-FNE engine model.
The gear ratio of the differential has been lowered to accommodate the performance of the 5S-FNE engine
and to ensure fuel economy.

BODY
To install the fuel tank in the front area of the luggage compartment, the upper back panel has been cut
for the 5S-FNE engine model.
To prevent reducing the rigidity of the body due to the upper back panel that has been cut out, as well as
for installing the fuel tank, rear seat back, and package tray trim, a performance rod is used for joining both
rear suspension strut towers for the 5S-FNE engine model.
The luggage door support has been changed from the torsion bar to the damper stay type for the 5S-FNE
engine model.
To prevent reducing the capacity of the luggage compartment due to the installation of the fuel tank in the
luggage compartment, the shape of the rear floor pan has been changed.
