2024 Toyota Tacoma — catalyst efficiency code but car drives normally

FlatSixSeller408Community StarterAug 3, 20262024 Toyota Tacoma TRD Off-RoadMiami
2024 Toyota Tacoma TRD Off-Road, about 41,500 miles. A catalyst efficiency code came back after clearing once. The car drives normally and there are no misfire codes. Before condemning the catalytic converter, what sensor/data checks are worth doing?

Log the conditions before you spend. If a shop can't duplicate it on the 2024 Toyota Tacoma, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. On “catalyst efficiency code but car drives normally,” that was the fork that mattered for me. Any freeze-frame data saved? If it repeats twice more I'll book time.

Ask what changed right before it started. If a shop can't duplicate it on the 2024 Toyota Tacoma, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. A shop burned me once by skipping that step. I'm in no rush to be a hero on it.
