I reset codes after the heater calibration. The heaters are so low of resistance they are almost like the wire so the computer figures out the actual resistance by measuring the current.

A minor change in the resistance say at a connector or in the heater or inside the DME will cause a heater error.

The only cure I've found was outlined above.

I use Bosch on all my O2. I have zero problem using oe or oem part for any part of the car. For non mission critical parts I will use knock off. Especially wheel afford sensors which are so easy to change and are not likely to stand you. I would maybe bring a spare on a long trip.

I only idled the car and off. Did that twice. Then I cleared the codes it would prob take five hot/cold drive cycles to clear the O2 codes on their own. You can reset your emission monitors faster I would reset.

Use the obd main menu to read monitor status.
