Saip problems/questions

828 Views 5 Replies 4 Participants Last post by  zmaninco
I recently replaced my saip and combi valve due to a p0411 code. Just a few days later I am showing this code again. The saip is working but when I feel the hose that goes into the air box it feels as if it is blowing air out. If I recall correctly it is supposed to sucking air in. I have to pass emissions in a month so I'm trying to get this resolved. Anybody know what could be causing this?

Thanks in advance

I don't think it is the fuse or relay because the pump is still turning on. I will check for vacuum to the combi valve though tomorrow. I hAve replaced the vacuum lines about 2 years ago. I suppose if I'm not getting vacuum maybe the n112 went bad.
