My check engine light came on so I read the codes. It reads "P2281 Air Leak Between MAF and Throttle Body" and "P2187 System too Lean At Idle". I can't seem to find a service manual for this thing can anyone
get me going in the right direction to find the leak? I looked around and don't see any broken/cracked hoses however I'm not very savy on where all the parts are at that may cause this.

Thanks, Brent

 

Brent,

Did you ever discover the problem with your car? I have a 2005 S40 T5 and I'm getting the same code (system too lean at idle 1st stage). I've seen no change in performance, but it makes me concerned to have a recurring check engine light, even after being cleared a few times. Sorry I don't have any advice/help, but I'd appreciate hearing how things have gone with your car. Thanks.

Sandy, I took all the hoses apart and made sure there were no leaks and the air flow sensor was clean. Then made sure the connections were secure. Then i reset the check engine light and the message didn't
come back.
