PO155 O2 Heater Circuit (Bank 2, Sensor 1)
These obviously are your O2 sensors. Banks= the side of the motor that is affected. i.e. Bank 1 Sensor 1 means (if im not mistaken) the O2 sensor on drivers side connected to your factory manifold and Bank 2 Sensor 1 means the O2 sensor on passenger side connected to factory manifold.
This could mean a few possible things as far as i know. One thing is that your 02 sensors are bad. It could mean that your 02 sensor is catching a slow reading from the ecu. Or it could be something else that im not aware of.
That might help you with your O2 sensors. Sorry I cant help you with anything else.
