o2 sensor
I have been fighting a lean bank 2 code. I just found on my obd reader sensor 2 bank 1 and 2 are not reading. I moved the bank 2 sensor to bank 1 and it reads. So my question is where does the sensor 2 wire go?

Re: o2 sensor
Maybe you have a good and a bad connection and a good and bad sensor. Put the goods together and that combination works.

I've moved them around today. They read on sensor 1 but not 2. I've followed the wires don't see anything wrong. I was just trying to figure out my lean on bank 2 code. It still hesitates.

Have you tried cleaning the connectors with electronic contact cleaner spray? Maybe there is some corrosion, you can buy the plugs separately if they need to be replaced, there is a part number stamped on them.
