I have a 2004 Mitsubishi Galant and am getting the p0155 code. So ok bank 2 circuit 1 O2 sensor is bad. There are 2 upstream O2 sensors. Is this location the one on the alternator side or the other side of the heat shield. In general, is bank 2 driver side or left side of engine?
P0155 Cylinder 2. 3 heated oxygen sensor heater circuit (sensor 1)
Front part of the engine toward the radiator
