crx b16 2nd o2 sensor wired to knock sensor?
I've had a 91 CRX with b16 for several years now and gas mileage has always been horrible. So recently I started checking things and today noticed my 2nd o2 sensor is wired straight to the knock sensor and neither sensor is wired to anything else yet I have no CEL. When I checked the ECU, wires are ran to the correct pinouts but the sensors are wired to each other, so I'm very confused as to what;s going on with the wiring. Should I remove the wires from the pinouts since they aren't going to the sensors and just run new wires? Any input would be helpful.

Maybe someone put in an exhaust pieced from an obd2 car and didnt know what to do with the other o2.
My obd0 integra pulls no code for having the sensor unplugged. It only pops a cel when the sensor is eay out of spec.
Get a new o2 sensor and wire it correctly
