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

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.”
