4. CHECK AIR INLET LINE
(a) Disconnect the air inlet line hose from the charcoal
canister.
(b) Check that air can flow freely into the air inlet line.
If air cannot flow freely into the air inlet line, repair or
replace it.
(c) Reconnect the air inlet line hose to the charcoal

5. VISUALLY INSPECT HOSES, CONNECTORS AND
GASKETS
(a) Check for cracks, leaks or damage.
HINT:
Removal or problems with the engine oil dipstick, oil
filler cap, PCV hose and other components may
cause the engine to run improperly. 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
improperly.
If necessary, replace any damaged parts.

BASIC INSPECTION
When a malfunction is not confirmed by the DTC check,
troubleshooting should be carried out in all circuits
considered to be possible causes of the problem. In many
cases, by carrying out the basic engine check shown in the
following flowchart, the location of the problem can be found
quickly and efficiently. Therefore, using this check is essential
when engine troubleshooting.
NOTICE:
Carry out this check with the engine stopped and ignition
switch off.
