DTC P145C: EVAP System Purge Flow Malfunction (Vacuum Purge)

DTC P145D: EVAP System Purge Flow Malfunction (Jet Purge)

NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.
- If DTC P145C is indicated alone, do the troubleshooting for DTC P0496 and P0497 using freeze data from P145C. If DTC P145D is indicated alone, do the troubleshooting for DTC P0496 and PI45A using freeze data from P145D.
- If DTC P0497, P145A, P145C, and P145D 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. Also check for a stuck closed EVAP canister purge valve.
- If any of the DTCs listed below are indicated at the same time as DTC P145C and/or P145D, troubleshoot those DTCs first, then recheck for P145C and/or P145D.
