Title: o2 sensors and air pump...
Post by: 20thanniver-ls on January 18, 2009, 03:02:45 PM
Is there any relation between the o2 sensors and how much air the air pump will blow out? When i reinstalled my o2's it seemed like my air pump pumped out more air then without them. Never really noticed it before...:hick:

how would you know if your air pump was pumping out more or less?

you said your pump pumped more air without o2's. i was wondering how you compared the two. like why you thought that. im just curious, cause i couldnt tell you how much air my pump blew out.  i think the pump blows more the faster the engine revs

But it does sound a little confusing - the air hose is still connected - i ran my engine a little before installing my o2's and put my hand over the air hose and did it again after i installed them and at idle it seems to push out more air. Its not a problem or antyhing i was just curious as to whether the o2's had any play in that, i mean i dont see why they would but i am not very educated on the EEC computer system so who am i to say anyway.

oh ok. that makes more sense. i was very confused reading that was all, that why i asked. im not very knowledgable about air pumps, but since im already here, the pump itself pushes more or less depending on engine RPM, the rest is controlled by vacuum.

Ok, cool thanks for the insight.
