2003 GMC Yukon Denali Question: O2 sensor location

I need to replace the bank 1 sensor 1 on my 2003 GMC Denalim I know that bank 1 is the first sensor before the converter. Is bank 1 sensor 1 on the driver's side or the passanger's side? -
Answer 1
Not sure of the engine in your vehicle, if you provide that information it would be helpful. But in most cases bank one will be the driver side of the vehicle. I hope this helps… -
