Solving P0455 on Your 2022 Honda CR-V
A P0455 code on your 2022 Honda CR-V means the EVAP system detected a large leak. As the final year of the 5th-generation CR-V, your vehicle may still be within Honda's basic warranty. The most common fix is the simplest: your gas cap.
What You May Notice
- Check engine light with P0455
- Possible fuel odor
- Gas cap not clicking when tightened
- Emissions test failure
Causes Ranked
- Gas Cap Seal (Very High Likelihood): Loose or worn seal. Replace for $10–$25 if out of warranty. Try tightening first.
- Canister Vent Shut Valve (Medium Likelihood): Honda vent valve sticking open. $150–$250.
- EVAP Hose (Medium Likelihood): Cracked or loose vapor line. $80–$200.
- Bypass Solenoid Valve (Low Likelihood): Honda-specific component. $120–$220.
- Charcoal Canister (Low Likelihood): Saturated from overfilling. $200–$350.
Diagnostic Steps
Tighten the gas cap firmly. Clear the code or drive 2–3 days. If P0455 returns, visit a Honda dealer for HDS diagnostics and a smoke test to locate the leak.
Warranty Check
Honda's basic warranty (3 years/36,000 miles) runs through 2025. The federal emissions warranty (8 years/80,000 miles) covers EVAP through 2030. Check with your dealer for free repair eligibility.
Costs If Out of Warranty
Gas cap: $10–$25. Vent shut valve: $150–$250. Hose repair: $80–$200. Smoke test: $100–$150. Most P0455 repairs are under $250.
Safe to Drive?
Yes. Your CR-V's 1.5T engine and CVT operate normally with P0455.
