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.
TerminalsResistanceTemperature
THA - E212.5 - 16.9 kW-20°C (-4°F)
THA - E22.19 - 2.67 kW20°C (68°F)
THA - E20.50 - 0.68 kW60°C (140°F)
If the resistance is not as specified, replace the MAF meter.
(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.
Torque: 1.68 N´m (17 kgf´cm, 15 in.´lbf)

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.

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.
