Thereafter the throttle valve is<br />

opened a predetermined value. If<br />

this value is achieved, the throttle<br />

valve is again switched so that it is<br />

not supplied with voltage. Now the<br />

mechanical spring must pull the<br />

throttle valve to the previously<br />

learned emergency running position<br />

within a predetermined period<br />

(spring test).<br />

Then the throttle valve is closed by<br />

the throttle valve positioner and the<br />

values, which are supplied by the<br />

angle sensors in the Throttle Valve<br />

Control Module -J338-, are stored by<br />

the Motronic Engine Control Module<br />

(ECM) -J220-.<br />

If the Motronic Engine Control<br />

Module (ECM) -J220- switches the<br />

throttle valve positioner so that it is<br />

without voltage during normal<br />

operation, this is indicated by the<br />

increased and hunting idle speed.<br />

The engine reacts slowly to<br />

accelerator changes.<br />
