My Yukon is showing code P0140 and P1153 which point to an oxygen sensor malfunction but this vehicle has 4 sensors. How do I know which one to replace?
Thanks

P1153 is for passenger side front O2 sensor. P0140 is for driver side rear O2 sensor.

With 120K if they are all factory sensors, I would go ahead and replace all four.
