2001 Hyundai Accent

On certain vehicles, driving for extended periods in extremely cold ambient temperatures can cause moisture to freeze inside the throttle body idle speed control circuit and in the throttle body bore, resulting in a higher than normal engine idle speed, and the throttle valve not closing fully. This condition may result in reduced braking effectiveness on deceleration, which in turn could result in a vehicle crash. Correction: Dealers will install a modified PCV hose and, on manual transmission equipped vehicles without air conditioning, install a condenser cover.
