Kwa Volvo Detroit Fuel Pressure Switch Sensor 23511176

(1) Kapangidwe ndi dera

Throttle position sensor yokhala ndi on-off output imatchedwanso throttle switch. Ili ndi mapeyala awiri olumikizirana, omwe ndi osagwira ntchito (IDL) ndi kukhudzana kwathunthu (PSW). Kam coaxial yokhala ndi valavu ya throttle imayang'anira kutsegula ndi kutseka kwa ma switch awiri. Pamene valavu yotsekemera ili pamalo otsekedwa kwathunthu, kukhudzana kwa IDL kosagwira ntchito kumatsekedwa, ndipo ECU imaweruza kuti injiniyo ili m'malo osagwira ntchito molingana ndi chizindikiro chotseka cha kusintha kosagwira ntchito, kuti athe kulamulira kuchuluka kwa jekeseni wa mafuta malinga ndi zofunikira za ntchito yopanda ntchito; Pamene valve throttle imatsegulidwa, kukhudzana kosagwira ntchito kumatsegulidwa, ndipo ECU imayang'anira jekeseni wa mafuta pansi pa chikhalidwe cha kusintha kuchokera ku liwiro lopanda ntchito kupita ku katundu wowala molingana ndi chizindikiro ichi; Kulumikizana kodzaza ndi katundu nthawi zonse kumakhala kotseguka pamtunda kuchokera kumalo otsekedwa kwathunthu a throttle mpaka pakati ndi kutsegula kochepa. Pamene phokoso limatsegulidwa ku ngodya ina (55 ya Toyota 1G-EU), kukhudzana ndi katundu wathunthu kumayamba kutseka, kutumiza chizindikiro kuti injiniyo ili ndi ntchito yodzaza katundu ku ECU, ndipo ECU imachita kulemetsa kwathunthu. kulamulira molingana ndi chizindikiro ichi. Throttle position sensor yokhala ndi switch linanena bungwe lamagetsi lamagetsi la Toyota 1G-EU injini.

(2) Yang'anani ndikusintha sensa ya throttle position ndi zotuluka pa-off.

① Yang'anani mayendedwe pakati pa ma terminals m'basi.

Tembenuzirani choyatsira choyatsira pamalo "CHOZImitsa", chotsani cholumikizira cha throttle position, ndikuyika choyezera makulidwe ndi makulidwe oyenera pakati pa screw limit screw ndi lever ya malire; Yezerani kupitiliza kwa kukhudzana kosagwira ntchito komanso kukhudzana kwathunthu ndi cholumikizira cha throttle position sensor multimeter Ω.

Pamene valavu ya throttle yatsekedwa kwathunthu, IDL yolumikizana yopanda kanthu iyenera kuyatsidwa; Pamene valavu ya throttle yatsegulidwa kwathunthu kapena pafupifupi kutsegulidwa kwathunthu, kukhudzana kwathunthu ndi PSW kuyenera kuyatsidwa; Pazitseko zina, kulumikizana konseku kuyenera kukhala kosagwirizana. Tsatanetsatane ikuwonetsedwa mu Table 1. Apo ayi, sinthani kapena sinthani sensa ya throttle position.
