I have a rex and i have done a swap with yalls motor. my car is an hf and it has a b18a with a pr4 ecu. i keep on throwing code 13 every time i plug in the ecu. i dont understand why it is doing this to me. what is causing this. ive searched and i am being told that the sensor is in the ecu but i am not for sure. i tried another ecu and it tells me the same thing. by the way it throws this code as soon as i plug in the ecu and turn the ignition on( not even started). Wtf please help

 

also how can i tell if the ecu is for a manual?

 

with my friend's DA throw the same code. that means the ecu went bad, u would need a new one. you can tell if its manual by the ecu name/code. they are different from auto

 

Some years/models the BARO sensor is built into the ECU, some years it's separate & you can replace it.

 

where is the barometric sensor.. geesh.. does anyone know??? dang...called honda and they don't even know.. acura may probably know, but if someone knows the location on 88-91 Civic and 90-91 TEG then share it please...
