Delivery Pipe
A delivery pipe with a wide passage that enables a large volume of gas to flow responsively has been
adopted to minimize the pressure loss.
A fuel pressure sensor and a fuel temperature sensor that help correct the fuel injection volume are
mounted on the delivery pipe.
Similar to the fuel shutoff valves for the fuel tank and the fuel pressure regulator, a fuel shutoff valve is
provided on the fuel inlet side of the delivery pipe to shut off the supply of fuel when the engine is stopped
or during abnormal conditions.
To discharge the fuel out of the delivery pipe during service, a discharge valve is provided.
Injector
For the injection of fuel in the gaseous state, injectors that allow the flow of a large volume of fuel and pro-
vide improved sealing performance have been adopted.

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.

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.

Injector Control
1) General
Fuel clearing control and injector unsticking control have been added to the injector control.
2) Fuel Clearing Control
While the vehicle is being driven at speeds higher than 60 km / h (37.5 mph), and the ignition switch is
turned OFF after the ECM has detected a low temperature condition of less than 25C (77F) of intake
air temperature, the ECM closes the fuel shutoff valve for the delivery pipe. However, instead of immedi-
ately stopping the engine, the fuel clearing control allows the engine to stop on its own after the fuel in
the delivery pipe has been used up. If the engine is running even after 2 seconds or more have elapsed
after the ignition switch has been turned OFF, the EFI relay is turned OFF to stop the engine.
3) Injector Unsticking Control
When the ignition switch is turned ON after executing the fuel clearing control, the injector unsticking
control activates two cylinders at a time to unstick the valve that is frozen stuck onto the valve seat. At
low temperature conditions. At this time, the shutoff valve remains closed so that the injectors will not
inject fuel.
Gas Leak Judgment
If the ECM has detected a gas leak through the signals received from the pressure sensors, the ECM closes
the shutoff valves and flashes the low fuel level warning light.
These functions are canceled by resetting the ECM (by disconnecting the negative [-] terminal of the bat-
tery), which enables the engine to start.
(The ECM should be reset only after performing a gas leak check and making sure that the leak has been
eliminated.)
NOTE: The low fuel level warning light also flashes when the fuel level is extremely low. The flashing
patterns shown below differentiates a gas leak from a low fuel level.

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.

AIR CONDITIONING
The air inlet mode selector of heater control panel has been changed from the lever type to the push button
type on the CE and LE grade models.
When the air outlet mode is set to the DEF or FOOT/DEF mode, the air inlet mode also changes to the
FRESH mode, has been also added on the CE and LE grade model.
A fully automatic controlled type air conditioning is used on the XLE grade model.
The basic construction and operation are the same as in the CAMRY SOLARA.
A defroster-linked air conditioning start up control has been continuing to use since the previous models
with air conditioning.

Heater Control Panel 
SRS AIRBAG
When the SRS airbag is deployed, a signal to shut off the supply of fuel is output by the airbag sensor assembly
to the ECM for the 5S-FNE engine model.
