Hello, I did some intense diagnosis and have more information for you. Every time I go on a small road trip more than 50 miles, my check engine light would come on. I used my scanner to see live data and noticed that bank 2 sensor 2 which is after the catalytic converter by the engine was fluctuating the voltage quite a bit. And once in a while it would go to 0.0 volts when I let go of the accelerator pedal. As you have said, I don t see any symptoms of a failing catalytic converter because even when the check engine light is on the car still has full power and don t feel a loss of power. Bank 2 sensor 1 doesn t fluctuate a lot and is steady. I have attached 2 videos of showing the operation of the sensor and you can see sensor 2 showing 0.000 volts when I was cruising at 45 MPH.
