DTC Troubleshooting (cont’d)
28. Monitor the OBD STATUS for DTC P1454 in the
DTCs MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 27,
go to the indicated DTC’s troubleshooting.
If the screen indicates FAILED, check for poor
connections or loose terminals at the FTP sensor,
the EVAP canister vent shut valve, and the ECM/
PCM, then go to step 1. If the screen indicates NOT
COMPLETED, keep idling until a result comes on. NOTE:
Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
This DTC is representative of an EVAP system purge flow problem. If DTC P145C is indicated alone,
troubleshoot 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, or 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 DTC
first, then recheck for P145C:
