Thereafter the throttle valve is
opened a predetermined value. If
this value is achieved, the throttle
valve is again switched so that it is
not supplied with voltage. Now the
mechanical spring must pull the
throttle valve to the previously
learned emergency running position
within a predetermined period
(spring test).
Then the throttle valve is closed by
the throttle valve positioner and the
values, which are supplied by the
angle sensors in the Throttle Valve
Control Module -J338-, are stored by
the Motronic Engine Control Module
(ECM) -J220-.
If the Motronic Engine Control
Module (ECM) -J220- switches the
throttle valve positioner so that it is
without voltage during normal
operation, this is indicated by the
increased and hunting idle speed.
The engine reacts slowly to
accelerator changes.
