What can fail
The PCV hose may be misrouted after a previous emission recall fix. Moisture can freeze inside the hose and throttle valve during extremely cold driving (-30°C or colder), preventing the engine from slowing when you release the accelerator pedal.
What the fix does
Dealers will inspect the PCV hose routing from the previous emission recall repair and reroute it if needed to prevent moisture buildup.
