It is definetly a Front Sensor Bank 2 Sensor 1 is the forward oxygen Sensor for Bank 2, Either this will be Cylinders 2,4 and 6 or 4,5 and 6 depending on the firing order. If your engine is straight front to back it will be most likely the Right Side front sensor. If your engine is Sideways it will be the Rear forward Sensor. Auto Zone should be able to provide you with this repair info when you purchase the Sensor from them. They are Part of AllData and have this info at their stores. My experience over the years have been to Diagnos this problem not just pull a code. Just because the Computer has a Oxygen Sensor Code does not condemn the Sensor. P0155 can be set due to a vacuum leak or even something as small as water getting into the Sensor O2 hole in the top of the Sensor.

P0155 is the 02 sensor warm up heater circuit. You need to replace the 02 sensor on the drivers side before the cat converter. The left, or drivers side has the #2, #4, and #6 cylinders and is therefore bank 2. Get a Mitsubishi 02 sensor so you know it will be the right one. While at the dealer have them check to see if the timing belt has been changed, it should be done every 60,000 miles. The hydraulic tensioner should also be replaced with the belt.

P0155....O2 Sensor Heater Circuit (Bank 2 Sensor 1)
Which means the sensor heater element is burned out. Had it simply been an O2 code error, then it would not necessarily mean the sensor was bad. But in your case, the sensor has to be replaced for sure. Try looking up the O2 sensor on http://www.autozone.com http://www.partsamerica.com to see if they identify the individual sensor locations.
