P0031 DTC (diagnostic trouble code) refers to the O2 sensor (oxygen sensor) located on Bank 1 in front of the catalytic converter. ... Essentially this P0031 code means that the resistance of the heater circuit is lower than normal.

Most often replacing the sensor will resolve this issue and code.
