Code 43 is fuel supply system...

first things first that you have to look at:

1)O2 sensor
2)Map sensor
3)Fuel filter
4)Injectors

Usually when you trip that code, it means that one of the above needs attention.

:cool:

2)Map sensor <---are you serious? didn't know these could throw that code.

No that's about it.
See, code 43 is really a mystery.

I've tripped code 43 a few times. Sometimes with two codes togher: 1(o2 sensor) and 43 once. I've changed the fuel filter, it still came on when i hit the car hard...you know what i mean.
Then i changed the o2 sensor and it never came back.
It also went off in my cb7 Accord(obdI). The car needed a tuneup and a new fuel filter and it never came back.

Do you have an aftermarket fuel pressure regulator? did you bump the psi up?

Clear the code.

Go drive, see if it comes back on within a week of driving.
Usually code 43 ghosts back and forth...

and it should come on with another code the next time b/c the Honda manual doesn't tell you how to diagnose code 43 by itself. Last time I checked...

It only came on once. It blinked on one day when i had 2 other people riding with me. After I got where i was going, I cut the car off and I haven't seen it since I turned the car back on.
