Hey dose anyone know what a code #43 fuel delivery system on hon-data s100 ecu. Mine just started flashing it and Im not sure where to begin trouble shooting it. I don't want any catastrophic failures due to running too lean, Ya know.

 

Had a 43 for a year, i'd reset the ecu and it would disappear for a couple days, and re-appear again. It ended up being my o2 sensor.

 

That makes sense. My O2 is old and I've had O2 trouble codes, Ill swap it out and see what happens . Thanks

 

Code 1 and 42 and code 2 and 43 are PRACTICALLY SPEAKING the same thing.

99.9% of the time it's your o2 sensor.

 

if you're having fuel delivery problems ,first off change you're fuel filter
just to be on the safe side ,but it's probly the o2 sensor

 

Thanks every one. I replaced the o2 and so far no light. The fuel filter was replaced with the swap 1mo ago but I took your advice (beana) and changed it any way. Im picking up a rear disc conversion tomorrow for $150 it comes compleat with trailing arms and all. I hope it goes on as well as the b-swap went.
