I am getting P0130 and P0135 codes from my 318ti.

I replaced the O2 Sensor, and the code still comes back after resetting the code.

P0130 is O2 Circuit Malfunction
P0135 is Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)

---

What could be causing this? Is there some kind of a fuse or relax for the o2 sensor heater?

could be a open circuit (broken wires). and/or corrision on the connectors... did u take a peek when replacing them..
