приветствую други
нужна помощь. мотор AFN, шаран 1998 г.в. в общем типичная проблема для турбированного двигателя - после 3000 об/мин турбина переходит в аварийный режим. диагностика показывает ошибки:
00519 - Датчик давления во впускном коллекторе-G71
28-10 - короткое замыкание на плюс - Непостоянно
00575 - Давление во впускном коллекторе
17-10 - диапазон регулирования - Непостоянно
в общем-то типичный передув или недодув. было сделано следующее: проверен клапан 75. сопротивление 16,9 Ом. на фишке клапана напряжение бегает от 2,8 до 6,4 В., геометрия турбины почищена, шток ходит без заеданий. вакуумный насос заменен, вакуумные шланги тоже, замерено значение вакуума - 6,5. в общем-то после всех проделанных операций проблема не исчезла. единственное, что смущает, что когда даешь газу по вакууметру вакуум не падает, а наоборот повышается.... куда копать дальше?
вот логи:
