Okay so I bought a white 89 CRX HF, and a 91 DA integra.
My homeboys from a local shop did the swap, the motor runs pretty strong with the stock PR4 but i'll probably use a PG7 i have.

Well, my CEL code is #13, atmospheric pressure. Does anyone know how to fix it or where that is located?

My friend also did a B18a1 swap into his 91 Crx si and used the PR4 ecu with no CEL's.
Is it the one black box on the HF's firewall?
Any help apreciated

BTW I lost my password, i'm not a noobie, member since 05 under z6_obd1_EF, just thought i'd mention that

 

OOPS! I guess i had my user name wrong, but i got it now, i reposted my question under my old username. member since 04,

 

If I remember correctly the baro/atmo pressure sensor is located next to the ECU. Right underneath the dashboard. Bolted on the pillar. Passenger side.

 

thanks, i'll check it out tomorrow

 

Yeah its a little black box almost looks like a relay, has 3 wires coming out of it. Pick up in a junkyard parts stores was like 200 bucks for it. Mine had the same issue.

 

usually, when you get code 13, it is not the PA sensor causing the problem - more than likely it is a problem with the MAP sensor or a vacuum problem - this is the PA sensor

 

thanks for the info guys.
ok, my 91 integra did not have a CEL so i really doubt its the MAP sensor.
I'm going to check it right now...

 

well, I just went to check it and it gave me a code 43?????? and 13.
I am obd0 so there's no code 43...

I took the PR4 off and plugged in my PG7.
The CEL is GONE!!! however i did not drive it i just had it iddleing.
BTW, it iddled i little uncommon, it almost died in a few ocasions.
Is this normal for PG7/B18 combos?
