AIR CLEANER ELEMENT (Replace)00100180058
The air cleaner element become dirty and loaded with
dust during use, and the filtering effect will be
reduced.
Replace it with a new one.
(1) Unclamp the air cleaner cover.
(2) Take out the air cleaner element, install a new one.
(3) Be sure when clamping the air cleaner cover in place
that the cover is completed closed.
4.EVAPORATIVE EMISSION CONTROL SYSTEM
(Check for leaks and clogging)
except evapo-
rative emission canister
1.If the fuel-vapor vent line is clogged or damaged, a fuel
vapor mixture escapes into the atmosphere causing
excessive emissions. Disconnect the line at both en ds,
and blow it clean with compressed air. Remove the f uel
tank filler tube cap from the fuel tank filler tube and check
to see if there is evidence that the packing makes improper
contact to the fuel tank filler tube.
2.The fuel tank pressure control valve installed on the vapor
line should be checked for correct operation.

battery are normal. Also, set the to the
condition:
lEngine coolant temperature:
lLights, electric cooling fan and all accessories: O FF
lTransaxle: Neutral (P range on vehicles with

Disconnect the crankshaft position sensor connector .
NOTE
Doing this will prevent the engine control unit fro m carrying
out ignition and fuel injection.
Cover the spark plug hole with a shop towel etc., a nd
after the engine has been cranked, check that no fo reign
material is adhering to the shop towel.

Caution
1.Keep away from the spark plug hole when crank-
ing.
2. If compression is measured with water, oil, fuel,
etc., that has come from cracks inside the cylinder ,
these materials will become heated and will gush
out from the spark plug hole, which is dangerous.
6.Set compression gauge to one of the spark plug hole s.
7. Crank the engine with the throttle valve fully o pen and
measure the compression pressure.
Standard value (at engine speed of
1,250 (178 psi)
Limit (at engine speed of
min. 935 (133 psi)
8.Measure the compression pressure for all the cylind ers,
and check that the pressure differences of the cylinders
are below the limit.
Limit:. max. 100
(14 psi)
9.If there’ is a cylinder with compression or a compr ession
difference that is outside the limit, pour a small amount
of engine oil through the spark plug hole, and repe at
the operations in steps 7 and
(1) If the compression increases after oil is added , the
cause of the malfunction is a worn or damaged pisto n
ring and/or cylinder inner
(2) If the compression does not rise after oil is added,
the cause is a burnt or defective valve seat,
is leaking from the gasket.
10. Connect the crankshaft position sensor
11. Install the spark plugs and spark plug cables.
12. Use the scan tool to erase the diagnostic
codes,
or disconnect the negative battery cable’ for
than
10 seconds and reconnect it.
NOTE
This will erase the diagnostic trouble code from
the crankshaft position sensor connector being disc on-
nected.

If the air which has mixed in the oil due to the ab ove
causes enters the high pressure chamber in the lash
adjusters, the air in the high pressure chamber wil l be
pressurized during opening of the valve, which caus es
the lash adjusters to shrink excessively, and an abnormal
noise will be generated when the valve is closed. T his
is the same phenomenon as the one when the valve
clearance has been excessively adjusted by mistake.
In this case, if the air which has entered the lash adjusters
is bled, things will be normalized.
