EVAPORATIVE EMISSION CONTROL SYSTEM
The method for detecting evaporative emission leaks has been changed from the previous internal pressure
monitor type to the vacuum type. The vacuum type forcefully introduces the purge vacuum into the entire
system and a leak is detected by monitoring the transitions in pressure. The changes associated with this sys-
tem are as follows:

A VSV for canister closed valve has been added to the fresh air introduction line.

The 3-way VSV for vapor pressure sensor has been discontinued, and a VSV for pressure switching valve
has been added.

The sensing position of the vapor pressure sensor has been changed from the charcoal canister to the fuel
tank in order to enhance the precision of the vapor pressure sensor.

The fresh air valve characteristics of the charcoal canister have been changed.

Diagnostic trouble codes (DTCs) have been added. For details on the DTCs, refer to the each Repair Manu-
al.

2. Exterior
Four new exterior colors have been added, for a total of 10 colors.
The design of the front and rear bumpers has been changed.
The bumper and the radiator grille have been made separate, and the radiator grille is chrome-plated.
The side protection molding has been increased in size. On the XLE grade model, chrome stripes have been
adopted for the side protection molding.

The styling of the 15º full wheel cover has been changed.
3. Interior
Wood-grain panels have been adopted in the interior of the XLE grade model.
CRS tether anchor brackets have been provided on the package tray trim. (except 5S-FNE engine Model)
A clock with an outside temperature gauge has been provided on the models with manual air conditioning.
4. 5S-FE Engine
The intake system from the inlet duct to the throttle body has been improved to increase torque and reduce
noise.
The direction of the rotation of the radiator cooling fan has been reversed.
A 2-way exhaust control system has been adopted on the TMMK made model.
Along with the discontinuance of the air assist system, the fuel injectors and the IAC valve have been
changed for the California specification model, in order to meet ULEV (Ultra-Low Emission Vehicle) re-
quirement.
The system for detecting evaporative emission leaks has been changed. For details, see the General 2000
Features section.
5. 5S-FNE Engine
Based on the 5S-FE gasoline engine, the 5S-FNE engine uses compressed natural gas. The fuel lines have
been designed exclusively for compressed natural gas application.
6. 1MZ-FE Engine
The system for detecting evaporative emission leaks has been changed. For details, see the General 2000
Features section.
A diagnostic trouble code (DTC) has been added for indicating a thermostat malfunction.
7. Automatic Transaxle
The overdrive switch has been changed to the momentary type. For details, see the General 2000 Features
section.
The differential gear ratio of the A140E automatic transaxle has been changed for the 5S-FNE engine mod-
el to accommodate the performance of the 5S-FNE engine.

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
the IAC valve have been changed for the California specification model.
Cooling SystemThe direction of the rotation of the electric cooling fan has been reversed.
Engine Control
System
The fast idle speed has been increased for the California specification
model.
The system for detecting evaporative emission leaks has been changed.
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
changed to improve the engine performance and to reduce noise.

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.

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.

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.

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.

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.
