How do you fix code po456 on 2004 rav4?

Answer 1

Code PO456 on a 2004 RAV4 indicates a small leak in the evaporative emissions system. To fix this, start by inspecting the gas cap for cracks or damage and ensure it seals properly. Check the EVAP hoses and connections for wear or leaks, and consider using a smoke test to identify any hidden leaks. If necessary, replacing faulty components like the purge valve or charcoal canister may also resolve the issue.
