P0141 o2 sensor heater circuit malfunction (bank 1 sensor 2) Which sensor is this front or back? It came on a year ago and I played with the front o2 sensor and it went away till now. Now it is back again and I checked the wire looks fine this time so I turned it off and two days later its back again. So which sensor is it I dont want to replace the wrong one. Any help would be great Thanks

Problems don't fix them selves. They may be intermittent though.
