got a problem i have a 95 lx 4 dr non-vtech. my check engine light came on and its code 43 (fuel supply system). its the second time this happens. what exactly is the problem. can anyone help me.

 

bad O2 sensor
be sure to get a OEM brand replacement

 

but wouldnt my o2 sensor code pop up instead of that one. im just asking because it makes no sense to me

 

got a response back about it being two different things anyone know?

 

i looked up the code myself from Honda material. it's the O2 sensor.

 

That is a code that sorta got lost in translation, it means the O2 sensor is reading 'unburned' oxides. Check for anything that might make the car run rich, old spark plugs, plugged up air filter, coolant temp sensor...etc.
