Question about 2004 GMC Sierra 2500
I have an 04 gmc yukon and the check engine light came on. The code tells me that the bank 2 sensor 2 is bad which is the post-cat sensor. What I can't figure out is which side is bank 2 located on. The driver or passenger. The engine is 5.3L Vortec flex fuel. The vin offers a "Z" if that matters in any way for engine type. HELP!!
