DTC P145C: EVAP System Purge Flow
Malfunction
NOTE:
• Before you troubleshoot, record all freeze data and
any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
• If DTC P145C is indicated alone, do the
troubleshooting for DTC P0496 and P0497 using
freeze data for P145C.
• If DTC P0497 and P145C are stored at the same time,
check for a poor connection, a blockage, or damage
at the EVAP canister purge line between the EVAP
canister purge valve and the EVAP canister, or a stuck
closed EVAP canister purge valve.
• If any of DTCs listed below are indicated at the same
time as DTC P145C, troubleshoot those DTCs first,
then recheck for P145C.
