Since it's the second sensor it's not going to effect the fuel mix or drive. The code will probably come back. The code is indicating something is wrong with the sensor.

Unless it self healed or was just a fluke, probably in a dozen drive cycles or so. If you are worried stop by an auto store and have the codes read again. If its going to throw the light again it will probably have a pending code set by now. If its clear maybe you lucked out
