The sensor performance codes can cause the light to go on and off, especially if the sensor is only intermittently failing to read properly. It takes 2 trips to make the light come on, then if it completes 2 more trips ok, the light goes off.
A trip is one run from full cold to full operating temp while the parameters for the air/fuel sensor tests are met.
You're going to eventually need to get it to a shop that can get a Honda specific scanner and an oscilloscope on the air/fuel sensor to see if it's the sensor, or another issue that causes these codes.
There may be bulletins also that may apply, as some CRVs had issues with new sensors on older cars causing a similar code, the only solution is to reprogram the PCM to "see" the new sensor's operation as normal.
