FUEL SYSTEM SPECIFICATION
Use Only Unleaded Fuel Rated at 89
Octane or Higher
Fuel quality and additives contained in fuel have a s ig n if i-
cant effect on power output, drivability, and life of the en-
gine.
Fuel with too low an octane number can cause engine
knock.
Caution: Use of fuel with an octane number lower
than 89 may damage engine and exhaust system.
Notice:To prevent accidental use of leaded fuel, the
nozzles for leaded fuel are larger, andwill not fit the fuel
filler neck of your vehicle.
Do Not Use Methanol
Fuels containing methanol (wood alcohol) should not be
used in vehicle.This type of fuel can reduce vehicle performance and
damage components of the fuel system.
Caution: Use of methanol may damage the fuel sys -
tem.
Vehicle Fueling from Drums or Storage
Containers
For safety reasons (particularly when using noncom-
mercial fueling systems) fuel containers, pumps and
hoses must be properly earthed.
Static electricity build up can occur under certain atmo-
spheric and fuel flow conditions if unearthed hoses, par-
ticularly plastic, are fitted to the fuel-- dispensing pump.
It is therefore recommended that earthed pumps with in-
tegrally earthed hoses be used, and that storage con-
tainers be properly earthed during all noncommercial
fueling operations.

CLEARING FAILURE CODES
Notice:To prevent Engine Control Module (ECM) damage, the key must be OFF when disconnecting or reconnecting
the power to the ECM (for example battery cable, ECM pigtail connector, ECM fuse, jumper cables, etc.)
Parameters listed in the table may not be exactly the same as your reading due to the type of instrument or other
factors. If a failure code is displayed during the “TROUBLE CODE” in scan tool check mode, check the circuit for the
code listed in the table below. For details of each code, turn to the page referred to under the “See Page” for the re-
spective “Failure Code” in the below table.
Failure codes should be cleared after repairs have been completed.

FUEL SYSTEM
The function of the fuel metering system is to deliver the correct amount of fuel to the engine under all operating condi-
tions. The fuel is delivered to the engine by the individual fuel injectors mounted into the intake manifold near each
cylinder.
The main fuel control sensors are the Mass Air Flow (MAF) sensor and the oxygen (O2) sensors.
The MAF sensor monitors the mass flow of the air being drawn into the engine. An electrically heated element is
mounted in the intake air stream, where it is cooled by the flow of incoming air. Engine Control Module (ECM) modu-
lates the flow of heating current to maintain the temperature differential between the heated film and the intake air at a
constant level. The amount of heating current required to maintain the temperature thus provides an index for the
mass air flow. This concept automatically compensates for variations in air density, as this is one of the factors that
determines the amount of warmth that the surrounding air absorbs from the heated element. MAF sensor is located
between the air filter and the throttle valve.
Under high fuel demands, the MAF sensor reads a high mass flow condition, such as wide open throttle. The ECM
uses this information to enrich the mixture, thus increasing the fuel injector on-- time, to provide the correct amount of
fuel. When decelerating, the mass flow decreases. This mass flow change is sensed by the MAF sensor and read by
the ECM, which then decreases the fuel injector on-- time due to the low fuel demand conditions.
The O2 sensors are located in the exhaust pipe before catalytic converter. The O2 sensors indicate to the ECM the
amount of oxygen in the exhaust gas, and the ECM changes the air/fuel ratio to the engine by controlling the fuel
injectors. The best air/fuel ratio to minimize exhaust emissions is 14.7 to 1, which allows the catalytic converter to
operate most efficiently. Because of the constant measuring and adjusting of the air/fuel ratio, the fuel injection system
is called a “closed loop” system.
The ECM uses voltage inputs from several sensors to determine how much fuel to provide to the engine. The fuel is
delivered under one of several conditions, called ‘‘modes”.
Starting Mode
When the ignition is turned ON, the ECM turns the fuel pump relay on for 1 second. The fuel pump then builds fuel
pressure. The ECM also checks the Engine Coolant Temperature (ECT) sensor and the Throttle Position (TP) sensor
and determines the proper air/fuel ratio for starting the engine. This ranges from 1.5 to 1 at -- 36°C(--33°F) coolant
temperature to 14.7 to 1 at 94°C (201°F) coolant temperature. The ECM controls the amount of fuel delivered in the
starting mode by changing how long the fuel injector is turned on and off. This is done by ‘‘pulsing” the fuel injectors for
very short times.
Run Mode
The run mode has two conditions called ‘‘open loop” and ‘‘closed loop”.
Open Loop
When the engine is first started and it is above 690 rpm, thesystem goes into “open loop” operation. In “open loop”, the
ECM ignores the signal from the HO2S and calculates the air/fuel ratio based on inputs from the ECT sensor and the
MAF sensor. The ECM stays in “open loop” until the following conditions are met:
DThe O2 has a varying voltage output, showing that it is hot enough to operate properly.
DThe ECT sensor is above a specified temperature (22.5°C).
DA specific amount of time has elapsed after starting the engine.
Closed Loop
The specific values for the above conditions vary with different engines and are stored in the Electronically Erasable
Programmable Read -- Only Memory (EEPROM). When these conditions are met, thesystem goes into “closed loop”
operation. In “closed loop”, the ECM calculates the air/fuel ratio (fuel injector on-- time) based on the signals from the
O2 sensors. This allows the air/fuel ratio to stay very close to 14.7 to 1.
Acceleration Mode
The ECM responds to rapid changes in throttle position and airflow and provides extra fuel.
Deceleration Mode
The ECM responds to changes in throttle position and airflow and reduces the amount of fuel. When deceleration is
very fast, the ECM can cut off fuel completely for short periods of time.

Circuit Description
When the ignition switch is turned ON, the ECM will activate the pump relay and run the in -- tank fuel pump. The fuel
pump willoperate as long as the engine is cranking or running and the ECM is receiving ignition reference pulses.
If there are no reference pulses, the ECM will shut off the fuel pump within 2 seconds after the ignition switch is turned
ON, engine stopped or engine stalled.
