codes 6 10 13

ok i am gettign these 3 codes on my civic with a b18a. 6 is water temp 10 is intake temp and 13 is atmospheric pressure. the car runs quite rich and backfires alot with a rough idel. where are these sensor located and witch one is most probaly the problem. thanks for any help!!

sweet thanks dude that will help for sure!

humm i changed the ecu and now i am not getting any codes!!i tryed 2 pr4 and now a pm6 thats isn't giving any codes. could this mean anything?

those three codes..................the problem lies in the sensor, the wiring, or the ecu.

if you swapped out the ecu and the cel does not come on, then, youve found the problem.

ah thats weird could it be that the 2 pr4's are not working properly and give the same codes?
