I am throwing 2 codes #5 and #41

#5 is MAP - in the service manual it says that it is some kind of vaccum problem, I can't find any problems. What are some common problems and fixes for this code.

#41 is O2 sensor - this one I know, but a little confused about. Its not hooked up, the reason being I can't find the plug for it. I just recently switched from an F22 harness running my H22 to an H23 auto harness, cause the F22 was a hack job. Before I had a fairly long plug that reached down to the downpipe under the intermediate shaft (or in that general area). Now I find no plugs like that at all. How is the H23's setup?

 

BUMP:

 

Isn't CEL #1 a o2 sensor code?

 

this is where I got my info,

41 is the O2sensor heater...

1 is the O2sensor

 

might wanna keep searching for the O2 sensor plug, cause then that'll get rid of your codes....I was throwing 3 codes when I did my motor swap to my 00 Prelude, and come to find out, I forgot to plug up my O2 sensor. Once I did that, all the codes cleared and haven't come back

 

would it be easier/cheaper to plug the o2 sensor instead of buying a new one?

I think I found the plug, but it is a female ended plug, and my O2 sensor is also female.
