Oyenera Volkswagen Jetta mafuta kuthamanga lophimba kachipangizo 51CP06-04

Kuthamanga kwa galimoto ya injini kumayendetsedwa ndi dalaivala kudzera pa accelerator pedal kuti asinthe mpweya wa injini, motero amayendetsa ntchito ya injini. Kutsegulira kosiyanasiyana kwamagalimoto kumawonetsa machitidwe osiyanasiyana a injini.

Kuzindikira kwa throttle position sensor yokhala ndi linear variable resistance output

(1) Kapangidwe ndi dera

Liniya variable resistance throttle position sensor ndi linear potentiometer, ndipo kukhudzana kotsetsereka kwa potentiometer kumayendetsedwa ndi throttle shaft.

Pansi pa kutseguka kosiyanasiyana, kukana kwa potentiometer kumakhalanso kosiyana, motero kutembenuza kutseguka kwa throttle kukhala chizindikiro chamagetsi ndikutumiza ku ECU. Kupyolera mu sensa ya throttle position, ECU ingapeze ma siginecha akusintha mosalekeza omwe akuyimira ma angles onse otsegula a throttle kuchokera kutsekedwa kwathunthu mpaka kutseguka kwathunthu, ndi kusintha kwa kusintha kwa kutsegula kwa injini, kuti athe kuweruza momwe injini ikugwirira ntchito molondola. Nthawi zambiri, mu sensa iyi ya throttle position, palinso cholumikizira cha IDL chosagwira ntchito kuti chiweruzire momwe injiniyo imagwirira ntchito. .

(2) Kuyang'ana ndi kusintha kwa liniya variable resistance throttle position sensor

① Kuzindikira kupitiliza kwa kukhudzana kopanda ntchito Tembenuzani choyatsira choyatsira pamalo "CHOZImitsa", chotsani cholumikizira cha waya cha throttle position sensor, ndikuyesa kupitiliza kwa kukhudzana kwa IDL pa cholumikizira cha throttle position ndi multimeter Ω. Pamene valve yotsekemera imatsekedwa mokwanira, ma IDL-E2 ayenera kulumikizidwa (kukana ndi 0); Pamene throttle yatseguka, sipayenera kukhala conduction pakati pa IDL-E2 terminals (kukana ndi ∞). Kupanda kutero, m'malo mwa sensa ya throttle position.

② Yeza kukana kwa potentiometer yofananira.

Tembenuzirani choyatsira choyatsira pa OFF malo, chotsani cholumikizira cha waya cha throttle position sensor, ndikuyesa kukana kwa potentiometer yofananira ndi Ω osiyanasiyana ya multimeter, yomwe ikuyenera kukulirakulira molingana ndi kuchuluka kwa kutseguka kwa throttle.
