If any codes relating to FTPS, CCV
or PCSV circuits are present, do all repairs associated
with those codes before proceeding with this trouble
area. |
-
|
If DTC P0455 is stored and MIL is
illuminated, before proceeding to evaporative system
test and repair, verify whether the customer was running
the engine uring
refueling. |
-
|
If an obvious cause for DTC P0455
is an engine running during refueling, erasethe DTC
P0455 using the Hi-Scan and do not repair the
evaporative system. However, the vehicle should be
monitored in case of reoccurrence of the concern which
may come from actual evaporative
system. | | |
