Code 41: Primary Oxygen Sensor Heater (what do I do?)
I have no clue where this is or what I am supposed to look for. Can anyone help me out? Thanks.

99% of the time, this is a failed heater circuit in the sensor itself. If you put a multimeter to it and find infinite resisance or nearly no resistance, that's your problem.
Honda troubleshooting flow charts go on for about four pages of BS before testing the sensor, it's rediculous.
