hi, my 92 ex flashed a code 41 Primary oxygen sensor heater .. if i replace my primary O2 will it fix this ? and if not what is the O2 sensor heater and where is it located? the primary O2 is the one sticking out of the exhaust manifold(headers) right? any help would be appreciated

Thanks

The heater is built into the sensor itself. And yes the sensor is sticking out of the exhaust manifold.
