Yep, thats right...when I put it in reverse the ecu throws a code 6. Turn the car off and turn it back on....no code. Put it in reverse the idle drops, tach bottoms out then bounces right back up then the cel lights up. The engine doesn't act like its going to die, just a quick drop in idle then right back...like 2 seconds. I also hear the main relay click when this happens. The main relay is about a month old (bought from Honda) and has checked out ok.

Any ideas?

 

i bet your cars a hf

you need to cut a wire going into the ecu....

6 is coolant temp. Maybe a wire is crossed somewhere....

 

or maybe a power short, u might be pulling to much power in reverse (the back up lights ) and im might me enough voltage drop to throw a code if they are wired in series

 

your both wrong

cut the wire at ECU pin B9 - green with black stripe

 

just for my own knowledge.. what did that wire do in the HF?

 

Reverse switch is the pinout description..cut it and it works like a champ...no code no drop in idle. Thanks again.

Yea I'm curious what the hell happened here also. I never knew about this.

I cut them all today and drove around for a couple hours no problems, even passed emissions test!
