If DTC P145C is indicated alone, do the troubleshooting for DTC P0496 and  
P0497 using the 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. 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, troubleshoot those DTCs first, then recheck for P145C.
