SES light went on again. The Peake tool read it as "Secondary Air System, flow too low." Before I trot off to the dealer, anyone know what this may involve?

sounds like the smog pump to me.

The vacuum hose for the smog pump check value is a common problem. It either breaks or becomes loose enough so it can't pull a vacuum. Just replacing the hose usually cures the problem. Of course there are other things that would cause the same code but that's the most common.

Hope that helps

Silverstreak,

I think the secondary air system just is needed to reduce cold start emissions in really cold climates. It´s function is to blow air into the richly mixed exhausts to speed up cat light-off.

I´ve had a false alarm from the secondary air system. Went away by itself.

I'm in South FLorida - it really doesn't get to cold here, especially this time of year. But you may be on the right track. It happened on start-up. I reset the system and will see what happens.
