I have a 41 code. It translates to the heater for the heated oxygen sensor. It seems to me that the heater would be in the sensor housing itself and the whole sensor needed to be replaced. What do you think?

Also my speedometer operates intermittently. Sometimes it works and most of the time it indicates 20 MPH whether I'm moving or not. Since I didn't get a code for the speed sensor, it seems like it might be the speedometer head. Would you agree?

Thanks to all that helped me out.
