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.

CAMRY ± NEW FEATURES36
5S-FNE ENGINE
1. Description
The 5S-FNE engine is a new engine that uses CNG (Compressed Natural Gas) as fuel, which has been devel-
oped based on the 5S-FE gasoline engine.
The main component of natural gas is methane (CH
4), which has fewer carbous (C) than gasoline (mean mo-
lecular formula: C
7.5H13.4). Therefore, the amount of CO2 discharged by this engine is approximately 70%
that of the gasoline engine. Furthermore, this engine achieves low-emission operation by precisely controlled
air-fuel ratio and using special catalysts for the CNG application.
However, because the fuel is in the gaseous form, its volumetric efficiency is low, causing lower power output
if this fuel is used in the base engine.
Therefore, the 5S-FNE engine has adopted the following features: a high compression ratio, the intake valves
with early closed timing, the intake and exhaust valves with increased lift, a low back pressure muffler made
possible by the 2-way exhaust system, injectors for gaseous fuel, and a catalytic converter designed exclu-
sively for CNG application. At the same time, precision air-fuel ratio control is effected through the use of
the air-fuel ratio sensor* and the heater oxygen sensor, thus achieving the level of performance that is equiva-
lent to the base engine. Moreover, this engine realizes extremely low emissions and restoring engine torque.
*: Already adopted on the California specification 5S-FE engine.

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.

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.

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.
