If the only code is the 43 from the cel. You can test or just replace the O2. I'd aslo ask how the normal tune up items are - are the plugs, cap rotor up to date?

fix the o2 sensor with a denso part

flush the tranny and fill with honda ATF, reset the codes. that should take care of it. especially since you're not having drivability issues.
