converter changed, o2 sensors changed, mass air sensor, intake gaskets upper & lower , spark plugs, wires , idles good no smells check engine light on. codes po158 2273, 2272 could this be ECM or wiring ?

Answer 1

P0158 -02 circuit high voltage (Bank 2 Sensor 2)

P2272 -02 sensor signal stuck lean (Bank 2 Sensor 2)

P2273 -02 Sensor signal stuck rich (Bank 2 Sensor 2)

P0158 is circuit high voltage, what this means is a disconnection , check the harness from the 02 connection to the harness, Clear the code, you can swap both 02  (downstream)  sensor and see if it moves if it does its the 02 sensor.
