2025 Toyota Camry — catalyst efficiency code but car drives normally

Log the conditions before you spend. Write temp, speed, and in-gear vs coast when the 2025 Toyota Camry does it — then decide on parts. If the cheap test changes it, stop and reassess. On “catalyst efficiency code but car drives normally,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' If it repeats twice more I'll book time.

If it were in my driveway, two 2025 Toyota Camrys can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. This is from a 2025 Toyota Camry in Washington DC with 31,500 miles. Was this after sitting overnight? Might be overthinking it, but I'd rather overthink than overspend.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2025 Toyota Camry does it — then decide on parts. Don't erase codes until someone who can help has seen them. This is from a 2025 Toyota Camry in Washington DC with 31,500 miles. I'd want a dollar figure or a measured spec, not 'should be fine.' A day of patience here is cheaper than a wrong part. If the story changes I'll post the new data.
