EM-1 with p28 conversion. car has ran fine with this setup for a long time, so its nothing to do with that. But just recently, my car threw code 41 for primary o2 sensor. I cleared the code and checked my 02 sensor and drove it, and now after about 200 miles its back on, but this time it is coupled with code 3. This is the code for the map sensor.

Can these be related or is my map going bad too? I am hoping that if i replace the o2 sensor it will eliminate the map code too, or is there something else wrong here??

 

If anything i would think that the map sensor would be causing the o2 code not the other way around.

 

that would make more sense but earlier i had just the o2 code.

 

get a map sensor from a junkyard and see if that fixes both

 

U know what map sensors work? its a b16 si tb.
