DTC P145C: EVAP SYSTEM PURGE FLOW MALFUNCTION

FUEL CAP WARNING MESSAGE SYSTEM TROUBLESHOOTING

Special Tools Required



Vacuum/pressure gauge, 0-4 in.Hg, 07JAZ-001000B



Vacuum pump/gauge, 0-30 in.Hg, Snap-on YA4000A or equivalent, commercially available

Do this procedure if the fuel cap warning message comes on frequently, or if the message does not go off after

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review the general troubleshooting information (see
GENERAL TROUBLESHOOTING INFORMATION ).



If DTC P145C is indicated alone, do the troubleshooting for DTC P0496 and
P0497 using freeze data from P145C.



If DTC P0497 and P145C are stored at the same time, check for poor
connection, blockage, or damage at EVAP canister purge line between the
EVAP canister purge valve and the EVAP canister, a stuck closed EVAP
canister purge valve.



If DTC P0496 and/or P0497 are also stored with P145C, troubleshooting
those DTC first, then recheck for P145C.
