I replaced the o2 sensor and this did not fix the problem.

Are you clearing the code out each time? Do a readiness test on it.

If you replace the sensor with an OEM and made sure you changed the correct sensor

it could be either a wiring issue or possibly (unlikely) a problem with the ECM. do some logging and graphing of the 02's voltage they should switch rapidly back and forth from rich to lean.
