INSPECTION
1. DISCONNECT MAF METER CONNECTOR
2. REMOVE MAF METER
Remove the 2 screws and MAF meter.
3. INSPECT MAF METER
(a) Using an ohmmeter, measure the resistance between ter-
minals THA and E2.

(b) Inspect for operation.
(1) Connect the MAF meter connector.
(2) Connect the negative (-) terminal cable to the bat-
tery.
(3) Turn the ignition switch ON.
(4) Using a voltmeter, connect the positive (+) tester
probe to terminal VG and negative (-) tester probe
to terminal E2G.
(5) Blow air into the MAF meter, and check that the volt-
age fluctuates.
If operation is not as specified, replace the MAF meter.
(6) Turn the ignition switch OFF.
(7) Disconnect the negative (-) terminal cable from the
battery.
(8) Disconnect the MAF meter connector.
4. REINSTALL MAF METER
Install the MAF meter with the 2 screws.

SFI SYSTEM
PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (-) TERMINAL CABLE FROM BAT-
TERY
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (-) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnosis before removing the
negative (-) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON THE FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) Take following precautions to prevent the engine misfire.
(1) Check proper connection to battery terminals, etc.
(2) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Take following precautions to handle the oxygen sensor.
(1) Do not drop the oxygen sensor or hit against an ob-
ject.
(2) Do not allow the sensor to contact with water.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to be out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will cause air suction, which makes the engine out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Disconnect the power by either turning the ignition switch
OFF or disconnecting the negative (-) terminal cable from
the battery before removing SFI wiring connectors, termi-
nals, etc.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (-) terminal cable from the battery.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative (-) cables.

(c) Do not a severe impact during removal or installation.
Handle all SFI parts carefully, especially the ECM.
(d) Be careful during the troubleshooting as there are numer-
ous transistor circuit, and even slight terminal contact can
cause further troubles.
(e) Do not open the ECM cover.
(f) When inspecting in rainy weather, take care to prevent
entry of water. Also, when washing the engine compart-
ment, prevent water from getting on the SFI parts and the
wiring connectors.
(g) Parts should be replaced as the original assembly.
(h) Care should be taken when pulling out and inserting the
wiring connectors.
(1) Release the lock and pull out the connector.
(2) Fully insert the connector and check that it is locked.
(i) Use SST for the inspection, the injector and the wiring
connector test.
SST 09842-30070
8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline may be spilled:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped on
its own, turn the ignition switch OFF.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with a rubber plug.
(7) Reconnect the fuel pump connector.

(b) When connecting the union bolt (fuel pressure pulsation
damper) on the high pressure pipe union, follow the pro-
cedure below:
(1) Always use 2 new gaskets.
(2) Tighten the union bolt by hand.
(3) Using SST, tighten the union bolt to the specified
torque.

(c) When connecting the flare nut on the high pressure pipe
union, follow the procedure below:
(1) Apply a light coat of engine oil to the flare nut, and
tighten the flare nut by hand.
(2) Using SST, tighten the flare nut to the specified
torque.

(d) Take following precautions to remove and install the injec-
tors.
(1) Never reuse the O-ring.

(e) Install the injector to the delivery pipe and lower intake
manifold as shown in the illustration.
Before installing the injector, spindle oil or gasoline must
be applied on the place where the delivery pipe or the in-
take manifold touches the O-ring of the injector.
(f) Take following precautions to disconnect the fuel tube
connector (quick type):
(1) Check that there is no dirt on the pipe and around
the connector before disconnecting them. If there
is, clean the dirt away.
(2) Be sure to disconnect it with hands.
(3) Type A:
When the connector and the pipe are stuck, push
the clicks of the retainer and pull the connector to
free to disconnect and pull it out. Do not use any tool
at this time.
Type B:
When the connector and the pipe are stuck, turn
and pull the connector to disconnect. Do not use
any tool at this time.
(4) Inspect if there is any dirt or the likes on the seal sur-
face of the disconnected pipe and clean it away.
(5) Prevent the disconnected pipe and connector from
damaging and getting foreign objects by covering
them with a vinyl bag.
(g) Take following precautions to connect the fuel tube con-
nector (quick type):
(1) Do not reuse the retainer removed from the pipe.
(2) Do not use any tool. Use hands to connect the re-
tainer to the pipe.
(3) Check if there is any damage or foreign objects on
the connected part of the pipe.
