What is your question?
The code said "engine coolant temperature sensor" so replaced it, then all lights came back on within 2 miles of driving through neighborhoods-no more than 35 mph. Temperature gauge goes up to "H" and then air conditioner starts blowing warm before check engine, TSC/DCS on & off lights come back on and engine seems like it's got less power. Had battery tested and replaced because code reset said "engine coolant temperature circuit low input". Now reset lights, car was cool from sitting for over a day. Started driving speeds up to 60 mph & Air conditioning stopped blowing cold after 3 miles, temperature gauge kept getting hotter until the check engine, TSC/DCS on & off all came back on and then temperature gauge went from "H" to "C" like it quit working. There's enough coolant in the reservoir, we added 2 qts of oil but nothing is fixing it. Any help would be greatly appreciated as I really need my car for medical visits.
