You have swapped the sensors and harness without changing the code. How new are the cats? Are they cheap ceramic core or steel core? Aftermarket cats are not required to meet oem standards and are often junk. Ceramic cores can break down at 1800 degrees. Steel are the true high performance cats and can stand 2800 degrees. Steel flow 20-30% better than ceramic with similar cell count. Cell count 200-400 are typical of the higher quality cats. You can test by removing the sensor and plugging the sensor port. Leave the sensor plugged into it's harness. The code should clear after a couple engine cycles.
