Hi,

I read a code that is causing an intermittent check engine light (Code 13 - Left Oxygen Sensor Error (Bank 2)). This has me slightly confused. Left would indicate drivers side sensor but Bank 2 would be passenger side since cylinder 2 is on that side. I read it using an Acron elite autoscanner. I saw the previous post https://ls1tech.com/forums/lt1-lt4-m...nsors-lt1.html that shows where they are at as well. I thought about jsut replacing both but would like to know if anyone has run into this as well and know what is correct.

In alldata it says code 13 is bank 1...Can your scan tool show live data or is it just a code reader? Here's a flow chart and pin out if you are handy with a DVOM.
