VDoP-B18C1

I threw a code 41.
(Primary Oxygen Sensor - Heater circuit malfunction)

I tried to bring it to tune the other day b/c i coulnt get the o2 sensor replaced in time. first they told me that hondata could probably overide the code, then later on they said i have to go get it fixed before i could tune.

is this true?

b/c according to previous threads on this cell this is not too important and that my car should not run any different.
