Recall 01V346000: PCV Valve Hose Routing
Defect: On certain passenger vehicles equipped with 1.5-liter or 1.6-liter engines that were originally sold or are currently registered in the states of Alaska, Colorado, Idaho, Illinois, Indiana, Iowa, Kansas, Maine, Massachusetts, Michigan, Minnesota, Missouri, Montana, North Dakota, Nebraska, New Hampshire, New York, Ohio, Pennsylvania, South Dakota, Vermont, Wisconsin, and Wyoming, while driving at a steady throttle opening for an extended period of time during extremely cold ambient temperatures (below approximately -5 degrees Fahrenheit with high humidity), moisture in the combustion chamber can freeze and block the positive crankcase ventilation (PCV) valve and hose. If the PCV hose freezes, combustion chamber gases are forced through the breather hose into the air intake hose and then into the throttle body. Moisture in the combustion chamber may freeze inside the throttle body bore and throttle body idle speed control circuit, resulting in the throttle valve not closing fully and a higher than normal idle speed when the accelerator pedal is released.
Remedy: Dealers will install a new, relocated PCV hose. On the 2000-2001 Accents equipped with 1.5-liter engines that were produced through Jan. 31, 2001, dealers will additionally install a heated throttle body. Hyundai has not yet provided an owner notification schedule for this campaign. Owners who do not receive the free remedy within a reasonable time should contact Hyundai at 1-800-633-5151.
