Thank you for that information.Codes are the way the OBD-II computer tells us there are problems with specific circuits, and don't necessarily indicate a component is bad. In this particular case, P0161 means the OBD-II computer has detected a malfunction with the heater circuit for the downstream Oxygen sensor for engine bank 2 (closest to the front of the vehicle).Possible causes for this code are:blown #9 A/F fuse (15A) in the auxiliary fuse box - left side of engine compartment by brake fluid reservoirbad wiring or connectionbad Oxygen sensor - see attached graphic for locationbad onboard computer (PCM)Please let me know if further assistance is needed for this issue.Best Regards.
