P0133 O2 Slow Response (reversed O2 connectors) - Hyundai

In most cases, a slow response DTC gets fixed with oxygen sensor replacement. What do you do when multiple sensors won’t fix it? Even though the root problem on this Hyundai was human error, the tests and methods I’m showing are still applicable to any vehicle using ‘normal’ zirconia O2 sensors.
