Code 14 = Replace IACV
Does a Code 14 always mean that the IACV is bad?
If NO, why?
I am hoping that this poll sheds light on one of the biggest misconceptions concerning Code 14 and the IACV.

My vote is NO... trouble codes indicate trouble with the part, not a faulty part. I've had a code 14 before, removed and cleaned the IACV, and voila, problem solved. Interestingly enough I've had it stick open at high rpm before - near 8k - triggering a CEL in the middle of an autocross run or drag pass. Funky.

True. Or the difference between a dirty one or bad connection.

NO! the IACV is exactally what it says, a VALVE that moves to let air in and out to control the idle
if it sticks it can throw a CEL but all it needs is a good spraying with carb cleaner.

A frequent code 14 on a OBD2 car usually indicates incorrect idle speed. I've seen this a million times and it is almost always corrected with the adjustment of idle speed and/or cleaning out the IACV.

I would definitely look into the IACV before you start compensating with the idle adjust screw. Take it off your intake manifold and clean it inside and out with WD-40 or any type of engine or brake cleaner.
