We just did the H22 swap and when we turned it on the two codes that came out were the 02 and iacv...can anyone get me any info as to what to do or how to fix it??

 

check your wiring, that's all I can say with that much info.

 

Right now were cleaning it and we are going to start it up again after erasing the codes and see if it throws any codes this time.

 

ok wait..

its a 4thgen accord right?

to clear the codes I think two wires are backwards.. I remember on my friends h22 accord we had to switch 2 wires around (they didnt match up at the ECU) but it still solved it and cleared his o2 and IAB codes..

I know there is something messed up about the 4thgen wiring, where you gotta switch two wires that arent the same color at the ecu.. if someone can clear this up and confirm that would be awsome..

 

Cool. Naw it's a 5 gen. but last night i was looking on the honda accord faqs and i found something similiar to what you said. We are going to swith two pins in the ECU and we're hoping that it clears the codes. Thanks man.

 

Well the swap is done but it threw out two codes. We have an idea that we still need to switch out the two pins A6 and A11 but the problem is that on the A6 port there is no wire there?? my car is an A/T could anyone help me as to what this means and what i need to do???? please.

 

are you sure you're looking at it right?

from the ECU side of the female connector (i.e. looking at the connector).

A6 is bottom 3rd from the right.
A11 is top 5th from the right.

 

The mechanic that's looking at it says that there isn't one we have been trying to figure out if it is gone or if there is supposed to be one there or what??? could you help?

 

I could tell you which wire goes to what with a few good pictures. if there was never a wire going into A6 then you never had an O2 heater.

that's not a serious statement, I find it unlikely that it didn't have an O2 heater.

 

as described in previous post.

 

Are you sure that this is the diagram for a 94 honda accord Ex ECU

 

how about some info on your car and swap in order to help you out. Otherwise we are just going to be pissing into the wind.

 

that's the pin out for an OBD1 ECU.

 

My car is a 94' Honda Accord EX obd1 A/T and i am swapping an 94' H22A JDM A/T into it we got it started followed all steps until we reached the switching of the A6 and A11 pin. The A11 Pin is existed but the A6 has a blank spot nothings there. So what i am trying to figure out is why isn't there a pin there and if anyone could get me a pin out diagram for my exact model and year. We've looked in tons of places but non have given the exact pin out for the ECU. So if you could tell me why there isn't a pin there or a Pin out that would help me i would greatly appreciate it.

 

let me know if that solves it.. i read in your other thread that you did some research on your own since the two other guys that actually know stuff on this forum don't seem to be around to help anymore?!! lol..

Let me know how it goes!

 

ya if you had the ex model p0a ecu the two wires are switched around in that ecu for some reason that will solve all your problems

 

do you know where those wires are on the p0 ECU i am using the Ex accord ECU

 

here's another pinout a little more detailed, includes info for A/T and M/T

Would this be the pinout for my Accord ECU i am using the Ex ECU not the H22A

 

Well i am using the Honda accord A/T 94' obd1 ECU on the swap with the H22A A/Tand we know that we have to switch the two wires ( the A11 EGR and the A6 02 heat sensor ) but the problem is that there is no wire at the A6 point. Can anyone with useful info help me please??

 

if you want exact diagrams, at least as close as you're going to find from the dealership (which would be even better)

I bought an entire car diagram from these guys and I've used it more times then I can remember.

 

well are you counting like this
135
246
and from the back side where the wires plug in to the ecu

 

they are a11 and a6

 

 

ok, I merged three threads from this user all about the same issue so a few posts may be out of order.
