I had a po131 code (o2 sensor bank 1 sensor 1 ) I replaced it shortly after was getting a p219a ( generic code ) found map sensor was reading 14.8 with engine off replaced sensor and still the same reading. For reference it’s reading almost 1/2 of what it should. I am going to check voltages today . Anybody have this issue and found something? Vehicle is a 2015 3.5 eco boost .
