P0137 O2 Sensor 1/2 Circuit Voltage Low

[New Liberty]

Pulled this code today. I've never had an O2 sensor go bad on me, so does this mean that it needs replacing? Could moisture be causing it?

It's has been raining heavily today, and couple that with the snow banks, that means that all the storm sewer greats are covered, and there are huge unavoidable puddles out (which I don't necessarily want to avoid).

This happened to me as well a couple of months back. It turned out that the wires going to the O2 sensor was rubbing on the front drive shaft and finally cut through. I spliced them back together and all was fine. Before getting to worried, crawl under and check the wires closely. For good measure take a can of WD-40 down with you and spray the connections.
Hope this helps
