ENGINE CODE p2259
 

My check engine light went on this week, so I had it hooked up to the computer to read the code. It came back with a code:

P2259
secondary air injection system control |B| circuit low.

after I had it hooked up, the engine light went off, i think the guy at the service station cleared it.

How serious is this? any one know what I can expect a repair to cost? and is this an internal failure that might be covered under the 100K mile mazda warranty on the motor?


Thanks.

I had this code prior to my engine getting replaced and I still get it from time to time. Not sure what it is. Could be related to my catless mid pipe but I don't think so.

Is that what it's referring to? I have no idea just a thought.

I was thinking it had to do with the air pump but I think the air pump is only a concern when starting the car. I couldn't find the part in the picture, does that eliminate the air pump? Wonder what the side effects of that are.

It's called exhaust air injection cover plate

actually it could be - my cat is broken on the inside; as soon as I get the money together I'm going to replace it - but i was talking to another guy i know - it could be that its trippin the O2 sensor and thats causing it to throw the code.

thoughts?
