getting error code 43 fuel supply system

[bal]

as title says was driving home today and engine light came on so checked the code and got 43 means fuel supply system any ideas??

a few people have said it could be the fuel pump not giving the motor enough fuel i just wanted to see if anyone has experienced the same problem b4.

cheers.

wait for ECU-MAN
he will solve ur problem

If the car seems to be driving ok,descent gas mileage,etc,then have a good hard look at the O2 sensor.

[bal]

yeah car seems fine no power loss and no change in milage

wheres the o2 sensor?? its a OBDII JDM b16a

[ECU-MAN]

O2 sensor is on the pipe before the cat converter.

you will want to check out the O2 sensor. it migth be a bit lazy.

also make sure you fuel filter isnt realy old and that you have a good clean air filter.

reset the ecu, it might just go away. but if it comes back have a close look at your 02 sensor.

[CRXer]

Theres 2,one in front of cat & one after,well thats where they are on a B18C,assuming yours similar.

U need the ECU-MAN or similar to give ya testing info,ive never looked into it personally.

Assuming ya running a clean air filter also?

EDIT: lol,well here he is now

[bal]

yeah air filter is clean but unsure when the fuel filter was replaced since i hav only had the car for not that long where about is the fuel filter located??

will check o2 sensor.

[bal]

if it is the o2 sensor that would make sense cause the cat recently got replaced could of the exhust shop have bumped it when welding it on or isnt it that easy to knock?

Does VTEC still kick in yO!11oneone

[bal]

ok chcked the o2 sensor visably there sint anything wrong with it. Its not loose or anything. im resetting the ECU tonight and if it comes back ill change the filter on the weekend

[spetz]

I don't think "visibly" without even taking the o2 sensor out you can make a judgement on how it's condition is

[ECU-MAN]

as above,

you have to test the output voltage from the O2 sensor in relation to what the engine is doing.

looking at it only confirms no one stole it :)

i had some code on my car. i went to the wrecker and got a new o2 sensor, fixed it.

the wrecker gave me a warranty on the sensor too :thumbsup:
