CEL P0054 (O2 Sensor)
My car just threw the P0054 code, Heater Resistance (Bank 1, Sensor 2). I have LTH and HFC. Can anyone tell me what sensor this is that I need to replace? Which side? Upstream or downstream? I tried googling but found nothing C63 specific. Thanks in advance.

Secondary O2 (post cats) heater circuit is bad. Bank 1 is driver side.

So bank 1 is driver side? I found conflicting information regarding the C63. Is this the correct sensor: http://www.partsgeek.com/catalog/200...en_sensor.html
