1. Block port B. Orally blow air through port A. Check that air
flows freely through port C with check valve resistance.
2. Block port A. Orally blow air through port B. Check that air
flows freely through port C.
Fuel Tank Vacuum Relief Valve (Built into fuel filler cap)NCEC0019S031. Wipe clean valve housing.
2. Check valve opening pressure and vacuum.

If results are unsatisfactory, perform Fuel Pressure Regulator
Check, EC-QG-30.
Fuel Pressure Regulator CheckNCEC00261. Stop engine and disconnect fuel pressure regulator vacuum
hose from intake manifold.
2. Plug intake manifold with a rubber cap.
3. Connect variable vacuum source to fuel pressure regulator.
4. Start engine and read indication of fuel pressure gauge as
vacuum is changed.
Fuel pressure should decrease as vacuum increases. If results
are unsatisfactory, replace fuel pressure regulator.
Injector
REMOVAL AND INSTALLATIONNCEC00271. Release fuel pressure to zero.
2. Remove fuel tube assemblies in numerical sequence as
shown in the Figure at left.
3. Expand and remove clips securing fuel injectors.
4. Extract fuel injectors straight from fuel tubes.
IBe careful not to damage injector nozzles during removal.
IDo not bump or drop fuel injectors.
IDo not disassemble or adjust fuel injectors.
5. Install fuel injectors.
Carefully install O-rings, including the one used with the pres-
sure regulator.
IUse bare hands to install O-rings. Do not wear gloves.
IApply a coat of engine oil (with a low viscosity of 5W-30,
etc.) to O-rings before installation.
IDo not use solvent to clean O-rings and other parts.
IMake sure that O-rings and other parts are clean and free
from foreign particles.
IBe careful not to damage O-rings with service tools or
finger nails. Do not expand or twist O-rings. If stretched,
do not insert them into fuel tubes immediately after
stretching.
IAlways insert O-rings straight into fuel tubes. Do not tilt
or rotate them during installation.
6. Position clips in grooves on fuel injectors.
IMake sure that protrusions of fuel injectors are aligned
with cutouts of clips after installation.

TROUBLE DIAGNOSIS Ð GENERAL DESCRIPTIONQG16I18DE
Symptom Matrix Chart (Cont'd)
EC-85

Component DescriptionNLEC0144The heated oxygen sensor 2 (rear), after three way catalyst, moni-
tors the oxygen level in the exhaust gas.
Even if switching characteristics of the heated oxygen sensor 1
(front) are shifted, the air fuel ratio is controlled to stoichiometric,
by the signal from the heated oxygen sensor 2 (rear).
This sensor is made of ceramic zirconia. The zirconia generates
voltage from approximately 1V in richer conditions to 0V in leaner
conditions.
Under normal conditions the heated oxygen sensor 2 (rear) is not
used for engine control operation.

On Board Diagnosis LogicNLEC0147The heated oxygen sensor 2 (rear) has a much longer switching
time between rich and lean than the heated oxygen sensor 1
(front). The oxygen storage capacity before the three way catalyst
causes the longer switching time. To judge the malfunctions of
heated oxygen sensor 2 (rear), ECM monitors whether the mini-
mum voltage of the sensor is sufficiently low during various driving
conditions such as fuel-cut.
