i got an engine light the other day and had it scanned...i dont know the actual code but aparently it's an emissions code meaning too much secondary air...anyone know what that means? im thinking maybe something is wrong with the second set of 02 sensors? any ideas?

 

I'm no expert in this area by any means, but secondary air sounds like the maf is detecting less air that what is going into the engine. ie, a leak b/t the TB and elbow maybe? That's what it sounds like to me. Easy check anyway. Maybe someone else will chime in.

 

sounds resonable but over the summer i realized my intake was half off of the tb for go knows how long but it didnt seem to have any problems then...thanks

anyone else have an idea?

 

secondary air injection...is the only thing i know of and that is the air pump. it is/was a recall i know for 96 and 97

 

If you can somehow get and post the actual code we can be better help.

 

yea i suppose that's true...i'll see if i can get it

 

In OBD-II, GM uses "secondary air injection" to stand for the A.I.R. system. Most likely cause of the problem is a blown AIR pump fuse - would set P0410, or a malfunction in the control system (P0412). There is a recall on the AIR system for all 1995 and newer LT1's.

 

sounds good...how would i go about claiming that recall? if i still can...those codes sound familiar but i dont have it with me

thanks

 

All you need to do is call a dealer and verify that the recall is applicable to your car, and that the work has not already been done. Its an emissions recall, so they have to do the work. You might want to do a search to see if you can find a record of the recall campaign number. Its been discussed a few times.

But check the fuse first... its a 25-cent repair, and might save you from having to take the risk of dropping your car off at a dealer.

 

TSB # : 99083

 

He's right

 

well, i wasnt guessing

 

Yeah but I was just about to post the same thing, so I confirmed instead

 

the code was P0410...so that should be the fuse...we'll see
