Well I've had this problem for a while now....here it goes. Well...I have the throttle setting pointing up, set for a 4 banger, map sensor 5in 5out, and everything works.....but It throws a cel. I checked the wiring 5 times and had other people check the wiring . Its all right. I just dunno. The map signal going into the afc is around 4.2v and when it comes out of the afc to the pcm it is around 6.4v . I dont know why its doing this, if you have ANY ideas let me know please. Also I think it may be due to an over lap of the TB on the AIS hole on the intake manifold....but it didn't do it before I had the afc so like I said before.....dunno
Thanks in advance
Eric

 

i thought for all honda's the S-AFC map sensor setting was 6 in and 6 out.

i dont think that will fix your problem though.........maybe your MAP sensor is bad?

 

forgot to add...its a neon I'll try changing the map sensot tomorrow
