Cleaning, Inspection, and 
Measurement Procedure

D

Clean the IAC valve O-ring sealing surface, pintle
valve seat and air passage.
– Use carburetor cleaner and a parts cleaning brush

to remove carbon deposits.  Do not use a cleaner
that contains methyl ethyl ketone.  This is an
extremely strong solvent and not necessary for this
type of deposit.

– Shiny spots on the pintle are normal and do not

indicate misalignment or a bent pintle shaft.

– If the air passage has heavy deposits, remove the

throttle body for complete cleaning.

D

Inspect the IAC valve O-ring for cuts, cracks, or
distortion.  Replace the O-ring if damaged.

D

In order to install a new IAC valve, measure the
distance between the tip of the pintle and the
mounting flange.  If that measurement is 28 mm (1.1
in.) or less, the valve needs no adjustment.  If the
measurement is greater than 28 mm (1.1 in.), apply
finger pressure and retract the valve.  The force
required to retract the pintle on a new valve will not
damage the valve, shaft, or pintle.

NOTE: Do not push or pull on the IAC valve pintle on IAC
valves that have been in service.  The force required to
move the pintle may damage it.

IMPORTANT:

Use an identical replacement part in

order to replace a valve.  IAC valve pintle shape and
diameter are designed for the specific application.

Installation Procedure
