Nzira yekuongorora sei camshaft sensor?

Ese mota dzemazuva ano dzakashongedzerwa nechikamu chinodiwa se camshaft sensor. Basa rayo guru nderokupa murairo kuitira kuti mafuta apiswe mumasilinda. Kana iyo sensor inokanganisa, zvakakosha kuona chikonzero chekutadza uye kuitsiva.

Kuita kweDPRV (camshaft position sensor) kunoenderana nehutongi hwekushisa. Kupisa kunoparadza. Iyo sensor haizoshande kana waya iyo yainotumira uye inogamuchira chiratidzo isiri yekurongeka.

Basa rinokosha rinoitwa nekuremara kana kusvibiswa kwe sensor pachayo. Uyewo, pasi pemamiriro ezvinhu akaoma, kushanda kwemotokari (kunze kwemugwagwa kutyaira, kutakura zvinhu), sensor inogona kuchinja kana kutonyanya kuipa, pfupi pfupi ichaitika. Kuti ubvise kuparara kwe sensor panguva isina kufanira, ita ongororo yayo.

Troubleshooting DPRV

Kana iyo Cheki Injini chiratidzo chatove pane pani (inogona kusagara ichipenya, asi ichionekwa nguva nenguva), iwe unongoda kuverenga iyo yekuputsa kodhi uchishandisa diagnostic mudziyo. Kana iwe usina mudziyo wakadaro uye hazvibviri kuutenga, unofanirwa kuonana nenyanzvi.

Mushure mekugamuchira iyo chaiyo yekuputsa kodhi uye kuibvisa, isu tinokurudzira kuti uite seti yezviyedzo zviri nyore. Kuvapo kweimwe yeDPRV kukundikana makodhi akanyorwa pamusoro haawanzo kuratidza kuti sensor inofanira kutsiviwa. Zvinoitika kuti chitubu chedambudziko chikanganiso mune wiring, chinongedzo, nezvimwe. Zvinokwanisika kugadzirisa matambudziko akadaro iwe pachako.

Asi kuti utarise kuita kwe sensor pachayo, unofanirwa kuita seti yezviito. Zvechokwadi, chiratidzo chacho chakaoma kuongorora pasina michina yakakosha. Asi ruzivo rwekutanga ruchapihwa ne diagnostics ine multimeter.

Nzira yekuongorora camshaft sensor wiring?

Kutanga, tarisa uone mamiriro eiyo sensor connector uye waya dzinoenda kwairi. Ita shuwa kuti hapana tsvina, mafuta, kana ngura imomo inogona kukonzera kukanganisa. Ongorora waya dzehurema. Izvo zvinoitika kuti matambudziko anogadzirwa newaya dzakaputsika, kushamwaridzana kwakashata kana kuremara mune insulating layer inokonzerwa nekuratidzwa kune yakakwira tembiricha. Waya dzeDPRV hadzifanirwe kusangana netambo dzepamusoro-voltage dzeiyo ignition system.

Zvadaro, tinozvitora, "anoziva" kuongorora kukosha kwekuchinja uye kunanga ikozvino (AC uye DC, zvichiteerana). Asi iwe unofanirwa kuwana ruzivo pachine nguva nezve izvo zviratidzo izvi zvinofanirwa kuve zve sensor inoshandiswa pamotokari yako. Mune mamwe ma sensors, zvibatanidza zvakagadzirirwa kuitira kuti iwe ugone kubatanidza mamwe mawaya kwavari kuti uverenge data ine multimeter.

Kana izvi zvisingaite, edza kudzima RPF yekubatanidza uye kubatanidza waya dzakatetepa dzemhangura kune yega yega yekubatanidza terminal. Zvadaro, isa chokubatanidza panzvimbo kuitira kuti waya mbiri dzibude kunze kwemuviri wayo.

Imwe sarudzo ndeyekuboora waya imwe neimwe netsono kana pini (chenjerera kuti usapfupise waya!). Mushure mekuongororwa kwakadaro, nzvimbo dzakakanganiswa dzekudzivirira dzinofanira kunge dzakaputirwa zvakanaka nematepi emagetsi kuitira kuti unyoro hurege kupinda mukati.

diagnostics yeaviri-waya camshaft chinzvimbo sensor:

• Kana mota ichishandisa electromagnetic DPRV, isa iyo multimeter kune AC modhi.
• Mumwe munhu anofanira kubatidza moto nekubatidza kiyi mukiyi pasina kutanga injini.
• Panofanira kunge paine voltage mudunhu. Batanidza imwe yemaprobes eiyo multimeter kune "pasi" (chimwe nechimwe chesimbi chikamu cheinjini yekupisa mukati), uye batanidza yechipiri mukuchinjana kune waya dze camshaft sensor. Kusavapo kwezvino pawaya dzese kunoratidza dambudziko mune wiring inoenda kune sensor.
• Itai kuti munhu ari mumotokari atange injini.
• Bata imwe multimeter probe kune imwe waya yeDPRV yekubatanidza, uye yechipiri kune imwe. Hunhu huchaonekwa pachiratidziro chemudziyo, uyo unofanirwa kuenzaniswa nekuverenga kwekushandisa kwakapihwa mumirairo yekushanda yemotokari. Sezvo mutemo, zviratidzo pahwindo zvinosiyana pakati pe 0,3-1 volts.
• Kusavapo kwechiratidzo kunoratidza kuparara kwe camshaft sensor.

Nzira yekuridza sei camshaft sensor 3 pini?

kuongororwa kwe-XNUMX-waya DPRV:

1. Tsvaga tambo yemagetsi, "pasi" uye waya yechiratidzo (shandisa bhuku rekugadzirisa), wobva waongorora kuvimbika kwewaya inoenda kune sensor. Iyo multimeter inofanirwa kuchinjirwa kuDC modhi.
2. Mumwe munhu anofanira kubatidza moto asina kutanga injini yekupisa yemukati.
3. Isu tinobatanidza dema probe ye multimeter kune "pasi" (chero chikamu chesimbi chemukati chinopisa injini), uye iyo tsvuku kune DPRV simba waya. Migumisiro yakawanikwa inofanira kuenzaniswa nemashoko kubva kumirairo yekushanda.
4. Mubatsiri anofanira kutanga ICE.
5. Bata dzvuku probe ye multimeter kune iyo chiratidzo waya yeDPRV, uye batanidza dema probe kune pasi waya. Muchiitiko chekutadza kwe sensor, iyo voltage ichave yakaderera pane yakataurwa mubhuku rekugadzirisa. Izvo zvinoitika kuti iyo multimeter haina kuratidza chero chinhu, iyo inoratidzawo kutadza kwe sensor.
6. Bvisa iyo DPRV uye ongorora iyo element yehurema hwemakanika kana kusvibiswa.

Iyo camshaft position sensor iri nyore asi yakakosha mudziyo, pakushanda kwayo iko iko kushanda kweinjini yekupisa kwemukati kunoenderana. Nokudaro, pakuziva zviratidzo zvekukundikana kwayo, zvakakosha kuita maitiro akakodzera ekuongororwa nokukurumidza. Izvo zviri nyore, uye kunyange mutsva, muridzi wemotokari asina ruzivo anogona kuzvibata.
