Fortunately, I have both a Peake code reader as well as the Bavarian Technic cable/program so I have read the code(s). Essentially, it says that the pre-cat oxygen sensor for bank 2 (I assume this is cylinders 4-6) is disconnected/unplugged. Another code on the Peake reader said that this sensor requires a "systemcheck".
No one has been under the hood anywhere near the sensors so it doesn't make sense to me that anything could actually be disconnected. Does this mean that the sensor has failed or can there be something else that triggered the error code? Any help from the technical experts on this board would be greatly appreciated.
