DTC Description

WARNING: This page is about a different variant/trim than selected.

The PCM closes the CCV at the charcoal canister to seal off the evaporative emission system and then opens PCSV to generate a vacuum in the fuel tank. This vacuum generation phase will determine if there is a large leak like tank cap open or canister shut off valve stuck open. The PCM sets DTC P045500 if the pressure in the fuel tank does not drop as low as predetermined threshold during predetermined maximum vacuum generation period.
