Code 155 is for a problem with the heater circuit in the O2 sensor for bank two. Bank two is on the side with cylinder number two.
Usually the sensor is faulty, but the heater circuit would need to be checked to be sure. The sensor has a built-in heater to get it hot quickly after starting the engine.
