NHTSA recall 01V346000
Vehicle Speed Control · Hyundai Motor America
Details
What's wrong: 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 blowby gases 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…
Why it matters: Moisture in the combustion chamber blowby gases 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.
The fix: Dealers will install a new, relocated pcv hose and will additionally install a heated throttle body on the 2000-2001 accents equipped with 1.5 liter engines that were produced through January 31, 2001. Owner notification began April 15, 2002.
