Obwohl sich diese Lösungen an sich bewährt haben, ist bei ihnen nachteilig, daß sämtliche elektrischen Verbindungen einzeln geführt werden. Das hat einen erhöhten Aufwand bei einer Neuinstallation, eine hohe Störanfälligkeit und eine erschwerte Instandhaltung zur Folge.Although these solutions have proven themselves, disadvantageous to them that all electrical connections be performed individually. That has increased the effort a new installation, a high susceptibility to faults and a difficult maintenance.

Zum Drosselklappensystem gehört auch ein Ventil, das die Aufgabe hat, vom Tank abgegebene Kraftstoffdämpfe einem Gasgemischhohlraum zuzuführen. Allerdings ist das Ventil vom Drosselklappengehäuse entfernt angeordnet. Deshalb ist eine gesonderte Schlauchverbindung zwischen dem Ventil und dem Drosselklappengehäuse notwendig. Außerdem muß das Ventil extra gehalten und ebenso wie der separat liegende Temperatursensor extra mit Steuerleitungen verbunden werden.The throttle valve system also includes a valve that The task is to deliver fuel vapors emitted by the tank Feed gas mixture cavity. However, the valve is from Throttle body located away. So that's one separate hose connection between the valve and the Throttle body necessary.

Die Entscheidung, wo das Motorsteuergerät am effektivsten untergebracht werden kann, hängt davon ab, welche Variante am günstigsten zu realisieren ist. Sind die Bauelemente temperatursicher und kostengünstig herzustellen, ist eine Unterbringung im Drosselklappengehäuseelement vorzuziehen, weil die Verdrahtungswege günstiger und übersichtlicher sind.
