I had recently had my oxygen sensor changed. The check engine light comes on then a day later it goes off again. A few weeks go by then the same thing happens. Go the codes checked at Auto Zone and it showed P0137 Oxygen Sensor Circuit Low Voltage (Bank 1 Sensor 2). Do I need to change it again or could there be another reason why this happens?

Is this the same O2 you previously replaced? I ask cause there are 4 on vehicle. If it is there maybe problem with circuit and will need proper diagnosis by a Tech.

Typical of a misfiring cylinder. You smell the unburned fuel, but the O2 sensor detects the unburned oxygen, not fuel. Since it says there is too much unburned oxygen, the Engine Computer commands more fuel to all of the cylinders. After that there is STILL that unburned oxygen that is detected.

You have four oxygen sensors. The left downstream sensor is different than the other three. The original wire colors are white, white, white, and black. A lot of aftermarket replacements use white, white, gray, and black.

Hi:
You can check a fuse by checking for continunity. As far as a relay, usually there are more than one in the relay block with the same part number. Make sure they are the same and switch them.
