ok, normally when it throws a 41 its just the o2 sensor if your lucky,check your voltage on while the engine is running from cold start, voltage should be at .1-.2V, after a period of about 2 min or so it should go into closed loop and read .1-.9 volts, if it dont then its ur o2 sensor, or you might just try unpluggin the battery for a couple minutes 2 reset the ecm, that is since you say you put in a new o2 sensor
Actually, his code is for the 'heater' cicuit of the O2 sensor, not the output.
If he replaced the O2 and wired it correctly he shouldn't have a CEL anymore. But yes, the ECU should be reset and then see what happens. If he still gets the code 41, I would suggest measuring the voltage of the heater circuit on a cold engine at the O2 sensor.

are you running stock headers? alot of time when you get a set of 4-2-1 headers it only has one o2 plugg next to the cat. if so youll have to get ur ecu chipped to bypass the first o2 sensor. i had the smae prob. for 3 months
