Ecu Error Code 43 Issue

[Latino CRX]

i just got CODE 43

Fuel Supply System
defective or malfunctioning fuel supply system

would that be the same for my B18c2 Ecu ??

if so does that mean new fuel pump or relay , or fuel rail or something??

I did a research for you, code 43 could be fuel system running lean. Most of people who had this problem changed O2 sensor and fixed the problem. Could be also Fuel filter. How the car is running ?

i was runnin really low on fuel then fueled up then engine light turned on so checked ecu and this was the code that came up ...

i think i mite be up for a new O2 sensor as my fuel consumption has been droppn alot quicker than usual ..

fuel filter is good i gave it a service 4000k's ago ..
