Engine light on and getting a PO158 code. Reasearch says I need to replace o2 sensor on side 2 bank 2.
What side is side 2? Driver or passenger side? Thanks

Code 158 is both sensor O2's not only 1 they are behind the converter. This can be an O2 problem not working a short in the circuit and or a ecm malfunction. Best to have a pro check this out instead of wasting money on parts that won't fix it.
