No. do you mean the front or rear o2? The front might be an A/F sensor. Big difference. But no, there isn't.
The front O2 sensor is located in front of the passenger side right under the fire wall. If you situate yourself on the right front fender of the vehicle, you will see the sensor under the hose that connects to the air filter box. It is connected on the top part of what seems like a catalytic converter. I happen to come accross this while searching for the rear O2 sensor. BTW, do you know where the rear sensor is located?
There is no fuse for the O2 sensor.

The front sensor is reading wether your air/fuel mixture is correct and computer makes adjustments according to a rich or lean reading from o2 sensor. The rear sensor is reading what comes out from the cat/converter to see if converter is doing is job in removing pollutants.
Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.
replace rear o2 sensor.
The O2 sensor on the 1994 accord dx, lx, or ex is the same, and there are two O2 sensor on the 1994 accord, fornt and the rear. Fornt one is located on the top and it is right on the header and the rear O2 sensor should locate on your cat converter right in the middle of your car. So check which sensor that you need and replace it.
The upstream O2 sensor is mounted in the ehxaust manifold The downstream O2 sensor is mounted in the exhaust pipe after the catalytic converter

usually it is a bad rear o2 sensor. only way to find out is to have someone(like autozone or advanced) rear the code.
it is the rear sensor bank 1 (the one after the converter)
