Default 91 integra spitting code 43

i have a 91 integra ls, its NA and the ecu had been screaming code 43, and as far as i understand that is the O2 sensor readout, turns out the wire was dissconnected like i figured it would be after laying under the car, i re connected it, and reset my ecu via the fuse box in the engine compartment. its still spitting code 43 at me.. any ideas ecu expert homies out there?

did you check continuity from the O2 sensor to the ECU?

if yes, and you have continuity, replace the O2 sensor

also check your fuel pump and fuel filter
