HELP: 02 Sensor question

Hope someone can help out here. I have a 96' V6 Automatic which I had all the 02 sensors changed when the vehicle had 60K miles on it. Yesterday, the Service Light came on (Present mileage 78K) and it revealed that 02 Sensor 1 Bank 1 was not having enough voltage or someting like that. Well I was thinking this might be just an incidental mistake since I just replaced the sensors about 10K plus miles ago so I used my scanning tool and erased the Error Code. What I want to know from the group of experienced people in this NG is do you think this is just a mistaken report by the computer or can a new sensor go bad this quick. Is this something that I should or should not worry about? These sensors are not cheap so if it did go bad I guess I just have to get another one. Anyway, thanks for any response.

If the O2 sensor code did not come back on after erasing it from memory, it's a soft code. Don't worry about it. Something might have triggered it, then stored it.... which is what it's programmed to do.

Just to be sure though, is the harness for the O2 sensor near your spark plug wires? If so, re-route it away from them (especially if their High Performance aftermarket wires)...

Just take off the sensor, disconnect from the harness.... check the wire for any cuts or fray's. Reconnect sensor, and make sure to apply some anti-seize on the bung. Wrap it up with some protective wire loom....

Just things to consider, but again, if the code did not come back, don't worry about it.

They can be bad of of the box, if that helps.

But, it could be a sign of other problems....
