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 FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, these precautions should be
taken.
(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) Precautions when handling the oxygen sensor.
(1) Do not allow oxygen sensor to drop or hit against an
object.
(2) Do not allow the sensor to come into contact with
water.
5. IF VEHICLE IS EQUIPPED WITH A MOBILE RADIO
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 run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc.,
first disconnect the power by either turning the ignition
switch to LOCK or disconnecting the negative (-) terminal
cable from the battery.
HINT:
Always check the diagnostic trouble code before disconnecting
the negative (-) terminal cable from the battery.

ON-VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
Check that the throttle linkage moves smoothly.
2. INSPECT THROTTLE POSITION SENSOR
(a) Disconnect the sensor connector.
(b) Disconnect the vacuum hose from the throttle body.
(c) Apply vacuum to the throttle opener.
(d) Using an ohmmeter, measure the resistance between
each terminal.

-VC - E22.5 - 5.9 kW
(e) Reconnect the vacuum hose to the throttle body.
3. INSPECT THROTTLE OPENER
(a) Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed.
Idle speed: 650 ± 50 rpm
(c) Disconnect the vacuum hose from the throttle opener,
and plug the hose end.
(d) Check the throttle opener setting speed.
Throttle opener setting speed: 1,100 - 1,700 rpm
If the throttle opener setting is not as specified, replace the
throttle body.
(e) Stop the engine.
(f) Reconnect the vacuum hose to the throttle opener.
(g) Start the engine and check that the idle speed returns to
the correct speed.
