NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see HOW TO USE THE HDS (HONDA DIAGNOSTIC SYSTEM) ).
- If DTC P145C is indicated alone, do the troubleshooting for DTC P0496 and P0497 using freeze date for P145C.
- If DTC P0497 and P145C stored at the same time, check for poor connection blockage, or damage at the EVAP canister purge line between the EVAP canister purge valve and the EVAP canister, a stuck closed EVAP canister purge valve.
- If any DTCs listed below are indicated at the same time as DTC P145C, troubleshoot those DTC first, then recheck for P145C.
