Just to add, a visual inspection might reveal just a broken or melted wire, because of where the oxygen sensors are located they are subject to to a rough environment I've seen oxygen sensor wires melted to the exhaust causing the same code in the past, so a visual inspection is important. The heater circuit wires are almost always 2 white wires going into the oxygen sensor. This code is for the front oxygen sensor, so that's the one in front of the catalytic converter. Check the whole wiring harness around the sensor.
