Temperatuur sensor koudstartventiel/warmloopregelaar

Berichtdoor Arens » 04 jul 2011, 23:06

Weet iemand tot welke temperatuur de sensor van het koudstart injector een signaal afgeeft.
En waar deze sensor zich bevindt. (die met de blauwe stekker ??)

Ik heb de koudstartinjector getest en die geeft geen benzine, stekker er af gehaald en gekeken of die een signaal krijgt maar die krijgt hij dus niet.
Dit testen is gebeurd met een koude motor en ong. 20 graden buitentemperatuur.

De koudstartinjector is verder goed ( deze is getest samen met de injectoren bij een gesp. bedrijf)

Ik heb dus het vermoeden dat de sensor kapot is, deze regelt volgens mij ook de aansturing naar de warmloopregelaar.

Misschien dat dit het slechte koudstarten/bokken van de motor veroorzaakt als hij op temperatuur is loopt hij mooi, na het uitzetten start hij meteen goed.
Staat hij 15 minuten stil is het weer slecht starten.

Stukje van het schema:thermotimeswitch.gifAls het schema overeenkomt met de werkelijkheid is het dus geen wonder dat hij bij 20 graden niets doet.

Beide draden bovenaan zitten aan het contactslot en krijgen spanning met de sleutel in de start stand en de versnellingspook in P of N.
Het gloeispiraaltje links (aan de G klem) heeft de schakelaar binnen 5 tot 10 seconden op temperatuur, zelfs als het vriest dat het kraakt.
Hij schakelt dus ook al gauw uit als het erg koud is.

Bij de "component locations" staat: "Thermo-Time Switch ... Top front of engine".

Hoi Leeflang bedankt voor het schema.
Hij stuurt dus ook de warm-up regulator (warmloop regelaar) aan ?

De sensor is dus waarschijnlijk niet kapot, want als de motor 15 minuten uitstaat is hij nog steeds warmer als 16 graden.

De motor krijgt ook teveel benzine bij de koudstart.
Van de week maar eens de warmloopregelaar demonteren en schoonmaken, misschien dat dat helpt.
