Hello adeo, thanks for your question in the Community.
Your fault Code means the O2 Sensor as you described.
It could be a faulty Front Heated Oxygen Sensor Bank 2
- Front Heated Oxygen Sensor Bank 2 harness is open or shorted
- Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks
- Exhaust gas leaks
In the most of these faults the O2 Sensor should be replaced.
