When the engine is started for the first time after parking overnight in cold weather (below freezing), some vehicles may exhibit the check engine light on with DTC P0451 (fuel tank pressure sensor: sensor characteristic malfunction) stored in memory. This concern may be caused by an increase in discharge resistance due to water accumulated and frozen in the canister vent hose.

Some vehicles may experience a rough idle with the check engine light on and DTC P0015 / P0524 stored in memory. P0015:00 - Exhaust CMP timing over-retarded P0524:00 - Engine oil pressure too low This is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump pressure relief valve or oil control valve (OCV). The temporary entry of the foreign object triggers a check engine light on, but rough idle will not be produced until a later time.
