CEL's : 1, 13, 43

1 is primary a oxygen sensor... guessing that's the one on the downpipe

13 = BARO Sensor (Atmospheric Pressure) defective circuit or unplugged / defective sensor ... WTF is that?

43 = Fuel Supply System defective or malfunctioning fuel supply system
doesn't sound good...


and i'm wondering why they come on 10 min. or so after i drive. any help appreciated!!

 

stand alone?
AFC?
what are you using

 

i have the same prob here. I have stock ECU, FMU, inline pump yada yada in a hatch equipped with B series motor and turbo. What is up with this I'd like to know.

 

are you running open downpipe? When I ran open header on my GSR, it would get code 43 sometimes, this was due to exhaust reversion, or air entering the exhaust and throwing of the O2 reading. This would also cause your code 1, or vice versa.

13 is not related to the other two, it's an intenal ECU sensor. Nothing to worry about, and is probably just a random fault.

 

i have hondata 2b... after i installed my new manifold, i been noticing a bigger and bigger exhaust leak. this is probably the problem!!! will have to look at it tommorow in the sun light. thanks for everyone's help!!
