Code is P0161 - O2 sensor heater circuit bank 2 sensor 2.
Does anything need to be changed?
I also ran mode 6, freeze frame, and full scan reports..
Found this thread regarding the sensor code.. maybe bad fuel when I filled up with 91oct? Not sure if I should change sensor or wait until I fill up with 94 oct again. Should I clear the code when I do fill up and see if it comes back? Add any fuel treatment??
Check Engine Light: Code P0141
