Ko fault code inorevei P0452?

Dambudziko kodhi P0452 ine chekuita neiyo evaporative emission (EVAP) system. Mota yako ine mafuta tank pressure sensor inopa ruzivo kune injini yekudzora komputa (ECM). Iyi kodhi ndeye generic diagnostic kodhi yeOBD-II ine mota dzakashongedzerwa, zvinoreva kuti inoshanda kune akawanda magadzirirwo uye mhando dzemota dzakagadzirwa 1996 uye gare gare.

Kana ECM yako yaona abnormally low low system pressure, inogona kuratidza dambudziko neEVAP system, inogadzira P0452 kodhi. Sensor iyi inoshandiswa kutarisa mafuta vapor pressure mutangi remafuta. Iyo sensor inogona kuiswa zvakasiyana mumhando dzakasiyana dzemotokari. Semuenzaniso, inogona kunge iri mumutsara wemafuta unobva pamafuta module kumusoro kwetangi remafuta, kana zvakananga kumusoro kwetangi. Izvo zvakakosha kuti uzive kuti sensor iyi inoshandiswa zvakanyanya pakudzora emission uye haina mhedzisiro yakananga pakuita kweinjini.

Iyo P0452 kodhi inogona kunge yakafanana kumota zhinji, asi inogona kunge iine akasiyana sensor kubuda. Semuenzaniso, sensor pane imwe kugadzira yemotokari inogona kuburitsa 0,1 volts payakanaka tank pressure uye inosvika 5 volts pakumanikidza kwakashata (vacuum), nepo pane imwe kugadzira yemota voltage inokwira sezvo yakanaka tank pressure inowedzera.

Associated evaporative emissions system dambudziko macode anosanganisira P0450, P0451, P0453, P0454, P0455, P0456, P0457, P0458, uye P0459.

Ndokumbira utarise kuti zvakakosha kunyatsoongorora uye kugadzirisa dambudziko rine chekuita neiyo P0452 kodhi kuti ive nechokwadi chekuvimbika uye nekuchengetedza nharaunda kushanda kweiyo evaporative emission control system.

Zvimwe zvinokonzera

Zvinogona zvikonzero zveP0452 kodhi zvinosanganisira:

  1. Kusashanda kwemafuta tank pressure sensor.
  2. Vhura kana pfupi dunhu mune sensor wiring.
  3. Kukanganisa kwemagetsi kubatana kuFTP sensor.
  4. Kutsemuka kana kutsemuka kwemutsetse unofamba uchienda kune vacuum cylinder.
  5. Mutsara wakanaka unoenda kutangi wakatsemuka kana kuputsika.
  6. Mutsetse wakavharwa mune evaporative emission control (EVAP) system.
  7. Kudonha gasket mupombi yemafuta module.
  8. Loose gasi cap, iyo inogona kukonzera vacuum kuvuza.
  9. Pinched steam line.

Zvakare, iyo P0452 kodhi inogona kunge iri nekuda kwekutadza kushanda kweEmissions Evaporative Control (EVAP) pressure sensor kana matambudziko ane sensor wiring harness.

Iyi kodhi inoratidza matambudziko anogona kuitika neiyo evaporative emission control (EVAP) system uye inoda kuongororwa uye kugadzirisa kuti ive nechokwadi chekushanda kwakanaka kwehurongwa.

Ndezvipi zviratidzo zvekodhi yemhosva? P0452?

Chiratidzo chete chinoratidza P0452 kodhi ndipo panouya sevhisi kana cheki injini. Muzviitiko zvisingawanzoitiki, kunhuhwirira kunooneka kwehutsi hwemafuta kunogona kuitika.

Nzira yekuongorora kodhi yemhosva P0452?

Iri dambudziko rinoda chero kusagadziriswa nekuda kwenzvimbo ye sensor uye maturusi anodiwa kuongorora dambudziko. Iyo sensor inowanikwa kumusoro kwegasi tangi mukati kana padyo nemagetsi emagetsi pombi module.

Chinhu chekutanga chaunofanirwa kuita kuongorora ese masevhisi bulletins emota yako. Iyi inogara iri tsika yakanaka sezvo vangangove nemhinduro.

Chechipiri, iwe uchaona mhando yezvinetso zvinosangana nevatengi nemuenzaniso uyu uye matanho anokurudzirwa ekuagadzirisa.

Chekupedzisira, mota zhinji dzine waranti yakareba kwazvo pamidziyo yekudzora emission, senge mamaira 100, saka zvingava huchenjeri kutarisa waranti yako uye kutora mukana kana uine imwe.

Kuti uwane iyo sensor, unofanirwa kubvisa tangi yemafuta. Iri basa rakaoma uye rine njodzi rakasiiwa kune technician ane lifti.

Muzvinopfuura 75 muzana yezviitiko, mumwe munhu haana kutora nguva yeku "latch" chivharo chegesi. Kana chivharo chemafuta chisina kuvharwa zvakasimba, tangi haigoni kugadzira purge vacuum uye vapor pressure haina kuwedzera, zvichiita kuti magetsi ekupinza ave akaderera uye kodhi yeP0452 isa. Dzimwe mota dzava nemwenje we"check fuel cap" padashboard kuti ikuzivise paunoda kuomesa zvekare.

Iwe unogona kutarisa mahosi emhepo anouya kubva kumusoro kwetangi remafuta kubva pasi pemotokari kuti utsvage mutsara wakaputsika kana wakakombama. Kune mitsara mitatu kana mina inomhanya kubva pamusoro petangi inoenda kudivi remutyairi njanji inogona kutariswa. Asi kana vachida kuchinjwa, tangi inofanira kuderedzwa.

Iyo technician ichashandisa yakakosha yekuongorora chishandiso iyo inoongorora iyo sensor mumotokari, pamwe nese mutsara uye matangi kumanikidzwa, yakagadziridzwa tembiricha, humidity uye urefu. Ichaudzawo nyanzvi kana tambo yemhepo yakashata uye kana magetsi ekubatanidza ari kushanda nemazvo.

Zvikanganiso zvekuongorora

Zvikanganiso pakuongorora P0452 zvinogona kukonzera kududzirwa kwakashata kwemafuta tank pressure sensor data uye, semugumisiro, kutsiva kusiri iko kwezvikamu. Zvakakosha kuitisa kuongororwa kwakarongeka kuti udzivise mari isingakoshi uye kugadzirisa dambudziko racho nechivimbo. Heano mamwe zvikanganiso zvakajairika kudzivirira kana uchiongorora P0452 kodhi.

  1. Unchecked fuel cap: Chikonzero chinowanzoitika cheP0452 kodhi chivharo chemafuta akasununguka. Usati waita diagnostics yakaoma, ita shuwa kuti tangi yakavharwa zvakanaka uye inogadzira vacuum. Dzimwe mota dzine light padashboard rinokuyambira kana butiro rakanganisa.
  2. Kuregeredza Service Bulletins: Vagadziri vanogona kuburitsa tekinoroji bulletins nezve akajairika P0452 matambudziko. Kuaongorora kunogona kukubatsira kuti unzwisise kana paine matambudziko anozivikanwa nemhando yemotokari yako.
  3. Bofu chikamu chinotsiva: Dambudziko rekodhi P0452 haisi nguva dzose yakabatana nemafuta ekumanikidza sensor. Kutsiva iyi sensor pasina kutanga kuiongorora kunogona kukonzera mari isingakoshi. Izvo zvakakosha kuti utarise zvese zvakabatana zvikamu zvakaita sewaya, hose uye zvibatanidza usati watsiva sensor.

Kubvisa zvikanganiso zvese zviri pamusoro uye nekuzviongorora zvine hungwaru zvinogona kukuchengetedza nguva yakawanda nemari kana uchinetsa P0452 kodhi pamotokari yako.

Kodhi yemhosva yakakomba zvakadii? P0452?

Dambudziko rekodhi P0452 kazhinji harina kukomba uye harikanganisi kuchengetedzwa kwekutyaira, asi rinogona kukonzera kuburitsa kudiki uye matambudziko ehupfumi hwemafuta.

Chii kugadzirisa kuchabatsira kubvisa kodhi? P0452?

Aya matanho ekugadzirisa anotevera anogona kudikanwa kugadzirisa iyo P0452 kodhi:

  1. Kutsiva sensor yekumanikidza mutangi remafuta.
  2. Tarisa uye wotsiva iyo sensor wiring kana paine mabreak kana mapfupi maseketi.
  3. Kutarisa uye kudzoreredza kubatana kwemagetsi kune FTP sensor.
  4. Tsiva kana gadzirisa mitsara yakatsemuka kana yakatsemuka.
  5. Bvisa tangi yemafuta kutsiva pombi yemafuta module chisimbiso (kana zvichidikanwa).
  6. Tarisa chivharo chetangi yegesi kuti chiomerwe.
  7. Tarisa uye, kana zvichidikanwa, shandura mitsetse yemhepo.

Zvinokurudzirwa kuti kuongororwa uye kugadziriswa kuitwe nenyanzvi inokwanisa, sezvo kugadzirisa kusina kunaka kunogona kukonzera mamwe matambudziko.
