Hey, my car threw a p0140 the other day. so on Thursday i bought a new 02 sensor for bank 2, seemed to work. this morning it just threw it again? any thoughts. the line doesn't seem to be cut or frayed or melted anywhere
The wires may be damaged on the harness somewhere or at the ECU. Do you have cats on your car? Or a non-fouler/O2 simulator? It's possible there is an exhaust leak or something else causing it.
