Hi All,

I just had a valve adjustment and fluid changes performed in my car by the honda dealership and noticed the check engine code when I got home... (Dealer is already closed for the day)...

I happend to have a OBDII reader and got a P0411 which says:
Seconday Air injection system inccorect flow....

So, like what does this mean? Can I drive the car back to the dealer?

I'll be calling the dealer tomorrow, but wanted to see if anyone knew how to fix this

... sucks I didn't notice it sooner....

Thanks!

After a few minutes of staring at the engine... I noticed a small grey shrink wrap type tube was hanging loose next to the engine (driver's side near the front). There are two of these grey shrink wrap tubes and the top one was hangin loose...

What do you think... was that the culprit? Should I re-set the code and turn it on to see if it comes back?

Could this have damaged my engiine (drove it at 80 MPH for 30 miles)...?

Man why does this happend every time I get my car serviced...

Thanks!

The secondary air injection system is for emissions. It relates to the system that pumps fresh air into the exhaust manifold after a cold start. It hurts nothing but fuel economy when it doesn't work. Of course, this generates the CEL.
I'll bet when they did the valve job, they either pulled off the tube for access ease or they knocked it off by accident.
Push the tube back onto the metal pipe and reset the CEL. In case you don't know where the tube goes, have a look here:

Thanks Xviper!

I hooked up the tube, reset the CEL and everything seems to be o.k...
