FAQ
Может ли P0501 вызвать проблемы с АКПП?
Да. АКПП использует данные о скорости автомобиля для определения момента переключения передач. Некорректный сигнал VSS приводит к неправильным или резким переключениям.
Влияет ли P0501 на систему ABS?
Датчик скорости, используемый для P0501, может совпадать с датчиком ABS или отличаться от него. При проблемах с P0501 стоит проверить и систему ABS.
