code 43!!! anyone??

[alb_accord]

ok code 43 its the fuel delivery system.
basicly the light comes on while you are at high speeds for a while. when the car idles,, it idles very low etc etc etc....

anyone find out what causes this code to come up and how to fix it???
i mean its driving me nuts just by thinking of it?

[accordaffair]

It seems to suggest you diagnose the O2 sensor.

Edit- Does the CEL come on along with the "poor driveability"?

im leaning towards the 02 sensor as well

Mine was a bad o2 sensor.

I had a problem with code 43 before, It was a problem with one of the injectors. I changed the set and never had the problem.

it has something to do with fuel, i would check everything fuel related but normally its the o2 sensor

x's 2. check fuel system first.

[mozzandherb]

Check the fuel system, then check the O2 sensor. I had a code 43 and then it started throwing a code 1 which is heated O2 sensor

i agree on O2. when i was getting that code i seafoamed it and it went away...

[SN2BH22CB7]

fuel system...check EVERYTHING...start with Seafoaming!.( like Mike suggested )..to TRY to clean the system!

if it still persists..... check the injectors...FPR...MFR...Fuel injection resistor....check the voltage of the fuel pump (* remove rear seat )


NOTE:..if you're getting a low pressure...you could have a clogged filter..or the MFR..is going bad not sending enough voltage to the pump.....pump could be going out....OR..the ECU itself could be going bad! you could have a/all bad injectors ...you just have to go through the process of elimination! ( test )..it could be something as SMALL as a faulty gas cap seal ( not holding pressure in the tank )

mine was map sensor. I know it has its own code but i went to the junk yard and got a map sensor after finally i got a code for map sensor. changed it and bang no MIL since.

[alb_accord]

well i was thinking as SN2BH22CB7 said to check the fuel system... but in the same time the error code comes up while i am driving 50mph and over for 10 min or so. this will eliminate the fuel pomp, injectors and all electrical.

what leaves me is bad ecu, fuel filter, 02 sensor(since its a boch)

i have done a few other reserches and asked a few of my friends who are tuners and they said that code 43 in a accord its a bitch.....
