I replaced my o2 sensor to solve a problem with passing emissions this worked for 2 months and then the check engine light came on again. A seperate code different from the first one(heater circuit bank1 one sensor 2) p0141. I replaced the catyltic converter as a mechanic suggested after this but the engine light persists with the same code. PLease help

That code has nothing to do with the cat converter. Did you replace the o2 at the rear of vehicle behind converter? Get back to us

Those bosch universal o2's are hit or miss, I find. The code is actually for the heater element, id install a oem one.
