CHECK AIR INDUCTION SYSTEM
(a) Check for air leakage in the air induction system [vacuum hose disconnection, cracks,
damaged gaskets, etc.]
.
HINT:
If the accelerator pedal is released after racing the engine, the inspection is easier to perform because
the vacuum inside the intake pipes increases and the air suction noise becomes louder.
If Short FT and Long FT are largely different from the normal values when idling (the intake air volume
is small) and almost the same as the normal values when racing the engine (the intake air volume is
high), air leakage may be present.
Perform "Inspection After Repair" after repairing or replacing the air induction system
.
OK:
There is no air leakage.
