I have an exaust leak, and I am showing code p1416, it said Auxilliary Emission Controls. Auto Zone couldn't tell me anymore, the dealer is closed, so does anyone have an idea what the code means? I haven't pinpointed the leak yet, it is on the passenger side of the engine, if it is from the manifolds, I am going to buy headers, but I am not sure what is going on yet.

I too have this code thrown off on my car and was wondering if it is safe to drive the car around until it is fixed and I was also wondering how easy it is to fix because a Chevrolet dealership wants to charge around 300 dollars to fix it (a service person at the dealership says it may be an EGR valve).

i do know the air pumps have a small valve, similar to PCV valve and it clogs up. if you can't blow through it, replace. since your code is air pump related this may be it.

i got another thread running here and can't get an answer to my code
