A P0497 code might mean that your PCM has detected a low flow condition in your evaporative emissions control system (EVAP) system. Your EVAP system is responsible for capturing fuel vapors in a closed reservoir (also called a canister) until your engine is prepared to burn them.
How do you fix evaporative emission system low purge flow?
- You should connect the hoses or loose connectors.
