so i had honda pull the code and thats what came up also called baro code i believe?
i jsut swapped a h22a with ecu into a 1992 prelude that orignally had an f what is causing this and how do i fix it thank u
we tried out several p13 ecus same problem,also when i step on the peddle all the way down it feels like it wants to go but doenst accelarte fast at all its like driving with my old f so i thought hmm maybe map or tps but wouldnt that come up as a engine code if those were bad

Get the exact name of the code as well as what # it is, will make it MUCH easier to help you. Follow this thread on how to read CEL's.

 

its code 13 baro metric(atmospheric pressure)
would a bad map sensor trip that code?cuz i tried several fresh ecus cuz i heard that baro sensor is in the ecu. so i think maybe the map sensor?

can you get specific information..... like maybe some pics...

most of all, exact numbers on the ecu and ecu's you have tried...

history of the wire harness thats running the H22... the person (or people) that did the swap..... did they know what to do (and what to expect)

with all these things known,, finding the root of the problem will be pretty easy

I did about 15 seconds of research on code 13, and so far I read that the baro sensor is in the GSR ecu's only..... but that was one search, and I don't know if thats true or not..... so thats why starting with all correct numbers on all hardware is key

 

u want pics of the ecu?and like the serial numbers?
the wiring harness we just modded the f22a harness and noah did it and he is quite knowladgeable about the wiring involved.

 

pics of anything is always nice.... but the exact numbers from your ecu will determine what the next step will be........

what does Noah think the problem is...... maybe have noah post a brief explanation of how he did the swap wiring and what-not, and his opinion on what he thinks is causing it.......

also if you are planning to get a chipped ecu, (assuming the swap was wired correctly)......dont worry about any of this.... because you can just disable the baro sensor, along with your knock, vtec pressure switch, eld, and much, much more... if you so desire to do so....

when I got a chipped ecu....... all those problems went away........

 

o really? so do u think i should just invest in one of those then?'
and would the code be causeing my car to not accelrate quickly?

 

having a chipped ecu only works if the wiring on the swap is all in order.... first things first..... write down ecu info, then we go from there.........

 

Baro = map sensor?
Check to see if tps and map plugs arent switched out with each other

 

hmm ok i will try that and sorry ben deez my car is covered by 3 feet of snow so once that goes away i will get that ecu number for ya

 

hey mervin, how bout posting some factual info on how the PA sensor is the MAP sensor.....

 

are you throwing multiple codes,... or just 13... because bad things can happen if you just start switching plugs around..... especially on a swap with modded and aftermarket components......

I'm still waiting for an explanation on how the PA = MAP..........?

 

nope im just throwing the code 13

 

shoot me a pm when you are able to gain access to your prelude for troubleshooting

 

ok thanks alot man

 

I looked it up in the Helms, you really need to get one if you're going to be working on your car. Atmospheric pressure sensor is built into the ECU and it only says to replace it with a known working ECU. You modified the engine internals and are trying to use a stock P13 correct? Could be the reason the ECU isn't reading things right since you said you already tried replacing the ECU with a known working one. You really need to get a P28 or P72 and have it tuned to run your motor.

 

its not really modded that much exhaust and intake and cam gears

 

and type s internals
