I just purchased my 2010 370 about three weeks ago w/ 11,000 miles on it. I have noticed that the voltage meter has been running about 14v. I thought that seemed a little high but I just kept running it. This weekend a the engine light came on. I took it autozone and they told me it had a code of UO164 which came up as nothing. They told me it was just to new. Upon further research, I believe it probably read PO164 which indicates "02 Sensor Circuit High Voltage (Bank 2 Sensor 3)". Any suggestions on what could be causing this?
