O2 sensor problem

Hi everyone. So my check engine light came on and the scanner says error P0137 (O2 sensor circuit low voltage bank 1 sensor 2). I went and looked and all the wiring to the sensors look good. So I figure I will replace the sensor tomorrow. I go to the gas station and fill up and as soon as I start the engine the light is off. My question is can filling up your tank have anything to do with the O2 sensor or is this just a weird coincidence. Any advice is much appreciated.

Probably a coincidence. Most likely a failing sensor and the code will likely come back. I wouldn't hurry to replace it until you see if it comes back. Make sure you use an NTK or Mopar sensor. Others like Bosch don't work well in these vehicles.
