Tracking Down P0455 on Your 2022 Toyota Camry
A P0455 code on your 2022 Toyota Camry means the EVAP system detected a large leak. Your 8th-generation Camry on the TNGA-K platform may still be within Toyota's basic warranty. The most common cause is the simplest: your gas cap.
What You May Notice
- Check engine light with P0455
- Faint fuel smell
- Gas cap not clicking properly
- Emissions test failure
Causes Ranked
- Gas Cap Seal (Very High Likelihood): Loose or worn seal. Tighten or replace ($10–$20). The #1 P0455 cause.
- Canister Close Valve (CCV) (Medium Likelihood): Toyota's vent valve stuck open. $130–$220 if out of warranty.
- EVAP Hose (Medium Likelihood): Cracked or disconnected vapor line. $80–$200.
- Purge VSV (Low Likelihood): Toyota's vacuum switching valve. $100–$200.
- Charcoal Canister (Low Likelihood): Saturated from fuel overfilling. $200–$350.
Diagnostic Steps
Tighten the gas cap and drive 2–3 days. If P0455 returns, a Toyota dealer will use Techstream to run EVAP tests and a smoke test to find the leak.
