Does anyone know what else to do. I've replaced my o2 sensor, fuel filter, cleaned injectors, and main relay also reset ecu. Can't get rid of the CEL caode 43. I driving me crazy, in turn my af meter is reading lean all the time, but my spark plugs eletrodes aren't white either, what else can I do???

 

go to the library, or book store, and buy yourself a chiltons and haynes manual, for your car....theses are a must when workin on your car, it has the ecu codes in them. your code would be refered to as a 4-3, wich is 4 longs, and 3 shorts, making this a 43...if you cant get to those books try pulling the ecu, and find some one with the same car, and put your ecu in theirs...see if it still throws that code 43...hope i can be of some help!

Well your orinigal post was kinda brief and lack description but I'll take a shot... I threw a code 43 once on my Teg... Code is for fuel supply... Do you have an aftermarket intank fuel pump...? If so, there's a sensor in the gas tank that I guess senses how much gas is being extracted and if the pump flows more than the sensor can read, it will throw a too rich/lean code...

Also, try checking your gas cap... I don't know what year your car is, but on newer Honda's if the gas cap is not tight, it will throw a code 43... Fuel supply/tank pressure... HTH...
