Air pump squeal during startup
Hey,
So I've been looking into my failing air pump and have not been able to find much documentation(yes, i checked the useless owners manual too) on proper function. I've got a couple questions..
What is the function of the air pump in the intake system?
Does it run constantly?
What are indicators of failure?
The problem I'm hearing is what I've always known to be a failing electric motor sound. Very high pitched whine and the pump appears to stop shortly after startup(I hear it wind down).
Thanks for any input.

Its function is to blow air through the manifold to help prevent the cat from clogging during cold starts. Thats why it only runs during startup
There are multiple (I want to say tons) of threads about this.
The high pitch noise is a good give away that it is failing.
Are you throwing any codes?
