So i got my s2000 back last week Friday from the shop and i have a check engine light i know i should take it back to the shop back but then again it could be something little i went to auto parts store this morning and used a OBD 2 here is what i got

Code
P0410 Secondary Air Injection System Malfunction
i looked into it and it looks like it could be some kind on air pump

mods: 70mm test pipe, custom exhaust and intake cover off

 

Did the shop mess with the engine at all?

 

i dont think they did it was mostly body work it was sitting there for about 6 weeks

 

just a wild guess but, make sure ur gas cap is on tight.

 

My car was throwing the same code a week ago. Took it to Honda and they couldn't find what was wrong. Double checked all the vacuum lines and sure enough, one of the hoses that go from the air control solenoid valve to the lower vacuum fitting underneath the fuel rail wasn't plugged in. Not sure how it got unplugged, but that solved my issue.

 

That was my second guess too i fulled up and i made sure the gas cap was tight on there but still CEL

 

after you plugged it back in did you pull out the (back up) fuse or should the light go away?

 

btw, put your intake cover back on. it might sound cool but you actually lose horsepower and tq with it off.

 

i always thought people would take off the cover for they can get some more air into it

thanks i will do so or buy me A 57 K&N

 

I pulled the back up fuse out for about a minute or so to reset the ECM
