My brakes squeal when cold.
Likely brake dust on the pads. Harmless, but if it returns warm, check pad thickness.

Active session
My Camry threw P0420. Catalyst efficiency. Is it the cat?
On a 2014 Camry, 9 times out of 10 it's the downstream O2 sensor — not the converter.
Before $1,200 at a shop, try:
- → Swap Bank 1 Sensor 2 (~$42)
- → Clear codes, drive 2 cycles
- → Re-scan

“I've been dealing with a difficult-to-diagnose CEL — mechanics wouldn't listen, dealer service wouldn't listen. I lost hope until this AI. We bounced ideas back and forth, helped me diagnose and confirm with utmost accuracy what was causing it.”

“Love it — worth paying for. But even just the free version is great. Very helpful, very detailed. No need to worry whether or not the guy at the parts store knows anything about mechanics.”
