F355B Check Engine Light

Yesterday my check engine light lit up on my way home from work. Today I I picked up an OBDII reader and it said it was code P0410, Secondary Air Injection System. I cleared it and then went
screaming around town
The light did not return all day. I am wondering what is the secondary air injection system? I recently put a Tubi on the F355.

Hi Tony,

way ta go getting a scanner and digging in!!

the secondary injection system is the pipes & hoses on the top of the exhaust headers on each side that supply extra air into the exhaust stream when the engine is cold. The system helps to rapidly heat the cats.

Thanks JR! I purchased an INNOVIA #3100 at a local auto shop for $130. Hopefully I will never have to use it again :-)
