The codes PDFs are on here and also in JTIS (on here, too). P1111 is meant to be there and is roughly system pass but do read the codes PDFs first several pages.
The PDF will show all the known causes for P1647 so study it and see what you can DIY. (Your current thing saying "chip" is wrong.)

P1647 - Linear O2 Sensor Control Chip (Bank 2 - Sensor 1) Driver's side - front sensor
Here are the other two options for the P1647 code.
The HO2 sensor 2/1 sensing circuit: short circuit to ground, short circuit to high voltage, open circuit.
ECM failure.
Make sure you get the correct sensor changed and a PCM reset - if your code comes back - the next step would be to check the O2 harness connection and wiring for any damage.
If the harness checks out then could possibly be a PCM failure (highly doubt it)
Rarely will the PCM fail but it does happen.
