Ikintu Ukwiye Kumenya Kubijyanye na Air Sensor

Ibisobanuro

Icyuma gikwirakwiza ikirere, kizwi kandi nka metero yo gutembera mu kirere, ni kimwe mu byuma bifata moteri ya EFI.Ihindura urujya n'uruza rw'umwuka uhumeka mu kimenyetso cy'amashanyarazi ikohereza mu gice cya elegitoroniki (ECU).Icyuma gipima urujya n'uruza kuri moteri nka kimwe mu bimenyetso by'ibanze kugirango bamenye ibitoro.

Ubwoko

Hariho ubwoko bwinshi bwimyuka yumwuka kuri sisitemu yo gutera lisansi igenzurwa na elegitoroniki.Ibyuma rusange byoguhumeka birashobora gushyirwa mubwoko bwa blade (plaque yamababa), ubwoko bwibanze bwo gupima, ubwoko bwimirasire ishyushye, ubwoko bwa firime ishyushye, ubwoko bwa muzingo bwa Karman, nibindi ukurikije ubwoko bwimiterere.

Uburyo bwo kumenya

Icyumaubwoko (isahaniubwoko) umwuka utembasensor

1. Gupima agaciro ko kurwanya

Banza, uzimye icyuma cyo gutwika, uhagarike umugozi wamashanyarazi wa batiri, hanyuma uhagarike insinga ihuza ibyuma byubwoko bwimyuka.Koresha multimeter kugirango upime guhangana hagati ya terefone.Agaciro ko guhangana kagomba kuzuza agaciro gasanzwe.Bitabaye ibyo, ibyuma bitwara ikirere byangiritse kandi bigomba gusimburwa.

2. Gupima agaciro ka voltage

Banza ucomekeshe inlet ihuza ibyuma byoguhumeka ikirere, hanyuma uhindure umuriro uhinduranya ibikoresho bya "ON" hanyuma ukoreshe multimeter kugirango upime voltage hagati ya VC na E2 no hagati ya VS na E2.Ibisubizo byo gupima bigomba kuba byujuje agaciro gasanzwe.Niba atari byo, sensor yimyuka yangiritse kandi igomba gusimburwa.

3. Gupima ibimenyetso bisohoka

Kuramo ibikoresho byo gutera inshinge, tangira moteri, cyangwa ukoreshe gusa intangiriro kugirango uzunguruke moteri hanyuma ukoreshe multimeter kugirango upime voltage hagati ya VS na E2.Umuvuduko ugomba kugabanuka uko gufungura icyuma bigenda byiyongera.Niba atari byo, bisobanura umwuka.Flowmeter yangiritse kandi igomba gusimburwa.

Ubwoko bwa muzingo bwa Karmanibyuma byumuyaga

1. Gupima agaciro ko kurwanya

Ubwa mbere, uzimye icyuma cyo gutwika, uhagarike umugozi w'amashanyarazi wa batiri, hanyuma uhagarike insinga ihuza metero zitwara ikirere.Koresha multimeter kugirango upime guhangana hagati ya THA na E2 ya metero zitwara ikirere.Agaciro gapimwe kagomba guhuza nagaciro gasanzwe.Niba atari byo, metero yimyuka yangiritse kandi igomba gusimburwa.

2. Gupima agaciro ka voltage

Huza umuyaga winjiza umuyaga winjiza ubanza, hanyuma uhindure umuriro uhindurwe kuri "ON" hanyuma ukoreshe multimeter kugirango urebe agaciro ka voltage hagati ya terefone ziri kumeza.Igomba kuba yujuje ibyangombwa bisabwa.Bitabaye ibyo, metero yimyuka yangiritse kandi igomba gusimburwa.

3. Gupima ibimenyetso bisohoka

Hagarika ibikoresho byo gutera inshinge, tangira moteri cyangwa ukoreshe itangira wenyine kugirango ukoreshe moteri, hanyuma ukoreshe oscilloscope gupima impiswi hagati ya E1 na terminal ya KS.Hagomba kubaho impinduka isanzwe ya pulse, bitabaye ibyo umwuka wangiritse ukaba ugomba gusimburwa.

Bishyushyefikirereandika ibyuma byumuyaga

1. Zimya icyuma cyo gutwika, uhagarike umuyaga winjira mu kirere, hanyuma ukoreshe multimeter kugirango upime ubukana buri hagati ya 3terminal na point de point de l'homée.Igomba kuba 0Ω.

2. Hindura umuriro uhinduranya kuri "ON" hanyuma ukoreshe multimeter kugirango upime voltage hagati ya terefone 2 na 3 za metero zitwara ikirere.Igomba kuba voltage ya batiri.Niba nta voltage cyangwa gusoma gusoma ni binini cyane, reba uruziga.Reba niba voltage iri hagati ya 4 na3 igomba kuba hafi 5V, bitabaye ibyo bivuze ko hari ikibazo cyumugozi uri hagati ya ECU na sensor de air cyangwa ECU.Niba hari umuyaga uhagaze mugihe uhagaze, reba neza ko imbaraga zubutaka bwa terminal # 2 ari 14V, bitabaye ibyo bivuze ko umuzenguruko uri hagati ya metero zitwara ikirere hamwe na pompe ya lisansi ari amakosa.Umuvuduko uri hagati ya # 3 na # 5 ugomba kuba hafi 1.4V mugihe nta mutwaro.Mugihe umuvuduko wa moteri wiyongera, voltage kumpera zombi igomba gukomeza kuzamuka, kandi agaciro ntarengwa ni 2.5V, bitabaye ibyo metero yimyuka igomba gusimburwa.

3. Zimya icyerekezo cya disike hanyuma ukureho metero yimyuka.Iyo nta muyaga uhari, voltage iri hagati ya 3 na 5 igomba kuba nka 1.5V.Koresha blower kugirango uhuhure umuyaga ukonje winjira muri metero yumuyaga, hanyuma uhindure buhoro buhoro.Mugihe intera yiyongera, agaciro ka voltage hagati ya terefone 3 na 5 bigomba kugabanuka buhoro buhoro, bitabaye ibyo umwuka ugomba gusimburwa no kubara.

Nizere ko amakuru ajyanye natwe twasangiye kubyerekeranye nikirere gishobora gufasha buri wese.Inyungu zose, ikaze kuvugana na VW Air Flow Sensor.
