4.16. Functioning проверяй, removal and инсталляцию of a measuring инструмент of a stream of поведение Проверка (L-Jetronic системы)
|
|
|
|
- Disconnect from the entrance союз of a measuring инструмент of a stream of поведение. Carefully open and close a zaslonka of the сенсор and проверяй jamming existence. Zaslonka at возвращаются flashes can bent and it тонна lead тонна the wrong measurements of resistance. Zaslonka can bent and remain в partially open ситуацию, causing enrichment of a смешивай and в ядре остановку idling.
|
- Disconnect from a measuring инструмент of a stream of поведение the electric socket.
|
|
- Проверка в метре ома resistance between contacts 7 and 8. Resistance should increase constantly (without “flat сайты”) at slow moving of a zaslonka of the сенсор from completely closed позицию в the completely open.
|
- Итак проверяй the сенсор of temperature of inlet поведение (в a stream measuring инструмент). Проверка в метре ома correctness of resistance between contacts 8 and 9 (look в иллюстрации above). Resistance at 20 ° With should make size from 2200 т. 2700 омов.
|
|
- ИФ resistance sizes correct, проверяй cables (look Head систему of onboard electric оборудование). Attach тонна a stream measuring инструмент the socket. convinced действовал ignition is switched off. Disconnect the socket from ЭКЮ (it is located under the dashboard on the right) and проверяй в метре ома resistance between contact 7 and 8. Carefully remove from a stream measuring инструмент a покрышку and observe resistance обмены денег when moving from a closed позицию в the completely open. The result of проверяй should семя, аса at the previous проверяй. ИФ в results any differences ары observed, в a cable there can повозки or short circuits.

Проверка of functioning (Motronic система)
|
|
|
|
- Проверка в метре ома resistance between noted contacts of the electric ЭКЮ socket and проверяй resistance обмены денег when moving petal. On early системы Motronic use contacts 7 and 9.
|
|
|
- On late модель - contacts 7 and 12.
|
- Resistance should increase continuously (without “flat сайты”) when moving a petal of the сенсор from completely closed позицию в the completely open.
|
|
Early системы Motronic differ the 35-contact electric socket; в late систему Motronic the 55-contact socket is used. |
- ИФ resistance size wrong, проверяй a cable.
|
|
Removal and инсталляция (всей системы)
|
|
- Disconnect from a stream measuring инструмент the electric socket.
- Remove в поведении purifier (look the Section Removal and поведение purifier инсталляции).
|
|
- Unscrew nuts and take a stream measuring инструмент from в impellent compartment or from в поведении purifier.
|
- Инсталляция is возвращаются тонны removal.
