P0239 - tsananguro yehunyanzvi yeOBD-II kukanganisa kodhi

Turbocharger Boost Sensor B Circuit Kusashanda

Ko kodhi P0239 inorevei?

Code P0239 ndeye yakajairwa OBD-II kodhi iyo inotangwa kana Injini Yekudzora Module (ECM) yaona mutsauko pakati peiyo boost pressure sensor B uye manifold pressure sensor (MAP) kuverenga kana injini iri kushanda nesimba shoma uye turbocharger pressure inofanirwa. kunge zero..

Aya macode akajairika kune ese magadzirirwo uye mhando dzemota, uye anoratidza matambudziko neiyo turbocharger inowedzera kudzvanywa. Nekudaro, iwo chaiwo ekuongorora matanho anogona kusiyana zvichienderana neiyo chaiyo mota modhi.

Makodhi eOBD haaratidze chakakanganisika, asi batsira nyanzvi kuona nzvimbo yekutarisa chikonzero chedambudziko.

Iyo supercharging (forced induction) inovandudza kuita

Turbocharger dzinoendesa mweya wakawanda kune injini kupfuura iyo injini inokwanisa kutora mukati meyakajairika mamiriro. Kuwedzera kwehuwandu hwemhepo inouya, yakasanganiswa nemafuta akawanda, inobatsira pakuwedzera kwesimba.

Kazhinji, turbocharger inogona kuwedzera injini simba ne 35 kusvika 50 muzana, ine injini yakanyatsogadzirirwa kubata turbocharging. Zvikamu zveinjini zvakajairwa hazvina kugadzirwa kuti zvimirire mutoro unogadzirwa nemhando iyi yekumanikidza jekiseni remhepo.

Turbocharger inopa kuwedzera kukuru kwesimba pasina kana kukanganisa pahupfumi hwemafuta. Ivo vanoshandisa exhaust gasi kuyerera kukonzeresa iyo turbo, saka iwe unogona kufunga nezvayo seimwe simba rekuwedzera pasina muripo wekuwedzera. Zvisinei, vanogona kukundikana kamwe kamwe nokuda kwezvikonzero zvakasiyana-siyana, saka kana pane dambudziko ne turbocharger, zvinokurudzirwa kugadzirisa nokukurumidza. Iine turbocharged injini, kutadza kweiyo turbocharger kunogona kuwedzera zvakanyanya mamiriro ezvinhu nekuda kwehuwandu hukuru hwemhepo yakamanikidzwa.

Izvo zvakakosha kuyeuka kuti yakajairwa turbocharged injini haifanirwe kugadziridzwa nekuwedzera kuwedzera kudzvanywa. Iyo mafuta ekuunza uye mavharuvhu enguva macurves einjini zhinji haatenderi kushanda pane yakakwira yekumanikidza, izvo zvinogona kukonzera kukuvara kwakanyanya kweinjini.

Ongorora: Iyi DTC yakada kufanana neP0235, iyo yakabatana neTurbo A.

Ndezvipi zviratidzo zvedambudziko kodhi P0239?

Iyo Cheki Engine mwenje inovhenekera kana DTC yagadzika. Iyo turbo module inogona kuremara nejini controller, zvichikonzera kurasikirwa kwesimba panguva yekumhanyisa.

Zviratidzo zveP0239 kodhi zvinosanganisira:

1. Iyo P0239 kodhi inoratidza dambudziko mukusimudzira kudzora wedunhu, pamwe inoperekedzwa nemamwe makodhi ane hukama nezvimwe zvikamu zvedunhu.
2. Kurasikirwa kweinjini yekumhanyisa.
3. Boost pressure measurements inogona kunge isiri padanho: isingasviki 9 pounds or more than 14 pounds, izvo zvisina kujairika.
4. Ruzha rusina kujairika rwakaita semuridzo kana kurira kwemanzwi kubva paturbocharger kana pombi.
5. Zvinogoneka kugogodza sensor kodhi inoratidza detonation nekuda kwepamusoro silinda musoro tembiricha.
6. General kurasikirwa injini simba.
7. Chiutsi kubva pombi yekuzadza.
8. Makanduru ane tsvina.
9. High injini tembiricha panguva cruising kumhanya.
10. Mhere inonzwika kubva kune fan.

Cheki Engine ichaitwa uye kodhi ichanyorwa kuECM kana izvi zvikaitika, zvichiita kuti turbocharger ivhare uye kuderedza simba rejini panguva yekuwedzera.

Zvimwe zvinokonzera

Zvikonzero zveP0239 dambudziko kodhi zvinogona kusanganisira:

1. Vhura dunhu re turbocharger pressure sensor ine mukati mekuwana.
2. Yakakuvadzwa turbocharger pressure sensor Chibatanidza chinokonzeresa dunhu rakavhurika.
3. Yakapfupika wiring harness pakati peiyo boost pressure sensor uye injini yekudzora module (ECM).

Izvi zvinhu zvinogona kuita kuti kudzvanywa kwekuwedzera kusatarisike, izvo zvinogona kusanganisirwa nematambudziko akati wandei, kusanganisira kuvuza kwevacuum, matambudziko emhepo sefa, matambudziko emarara, matambudziko ekupa mafuta eturbo, akakuvadzwa turbine blades, matambudziko echisimbiso chemafuta, nezvimwe. Mukuwedzera, panogona kunge kune matambudziko nekubatanidza magetsi uye sensors.

Nzira yekuongorora dambudziko rekodhi P0239?

Kuongorora matambudziko e-turbo kazhinji kunotanga nezvakajairwa sarudzo, uye kushandisa maturusi akareruka senge vacuum gauge uye dial geji inogona kunyatsoshanda. Pazasi pane kutevedzana kwematanho ekuongorora:

1. Ita shuwa kuti injini iri kushanda zvakajairika, hapana yakaipa spark plugs, uye hapana makodhi ane hukama neinogogodza sensor.
2. Nekutonhora kweinjini, tarisa kusimba kwezvibatiso panzvimbo yeturbine, intercooler uye throttle body.
3. Edza kuzunungusa turbine pane yekubuda flange kuti uone kuti yakanyatsobatanidzwa.
4. Ongorora kuwanda kwekunopinza kwemvura, kusanganisira vacuum hoses.
5. Bvisa iyo actuator lever kubva kune wastegate uye shandisa vharafu nemaoko kuti uone zvinogona kuitika dhizaini matambudziko.
6. Isai vacuum gauge muvhavha mune yekudyara manifold uye tarisa vacuum neinjini iri kushanda. Pachisina basa, vacuum inofanira kuva pakati pe16 ne22 inches. Kana iri pasi pegumi nematanhatu, izvi zvinogona kuratidza chakashata catalytic converter.
7. Wedzera kumhanya kweinjini kusvika 5000 rpm uye sunungura iyo throttle uchitarisa kusimba kwekuwedzera pane geji. Kana dzvinyiriro yacho yakakura kudarika 19 pounds, dambudziko rinogona kunge riri nevhavhavha yekupfuura. Kana iyo pfuma ikasachinja pakati pe14 ne19 lbs, chikonzero chinogona kunge chiri dambudziko neiyo turbo pachayo.
8. Tonhodza injini uye ongorora turbine, bvisa pombi yekuburitsa uye tarisa mamiriro emukati meturbine blades kukuvara, akabhenda kana kushaikwa mablades, uye nemafuta ari muturbine.
9. Tarisa mitsara yemafuta kubva kubhuroko reinjini kuenda kune turbine centre inotakura uye mutsara wekudzoka kune inodonha.
10. Isa chiratidzo chedhiya pamhino yeturbine yekubuda uye tarisa kupera kwekutamba kweiyo turbine shaft. Kana mutambo wekupedzisira uchipfuura 0,003 inches, zvinogona kuratidza dambudziko nepakati.

Kana iyo turbo ichishanda zvakajairika mushure mekuita bvunzo idzi, nhanho inotevera inogona kunge iri yekutarisa iyo boost sensor uye wiring uchishandisa volt/ohmmeter. Tarisa masaini pakati pe sensor uye injini yekudzora unit. Zvakakosha kuyeuka kuti haasi ese maOBD2 macode anodudzirwa zvakafanana nevagadziri vakasiyana, saka iwe unofanirwa kubvunza iro rakakodzera bhuku kuti uwane ruzivo.

Zvikanganiso zvekuongorora

Kuti udzivirire misdiagnosis, tevera mirairo iri nyore:

1. Tarisa iyo inowedzera pressure sensor hose yekuvhara uye kinks.
2. Iva nechokwadi chekuti magetsi emagetsi emagetsi akachengeteka uye kuti hapana kuputika kana kinks mumagetsi ekumanikidza.

Ndekupi kugadzirisa kuchagadzirisa kodhi P0239?

Kana iyo boost sensor isiri kutumira chaiyo yekumanikidza data kuECM:

1. Tsiva iyo boost sensor.
2. Tarisa iyo turbo sensor hoses uye zvinongedzo zvekinks kana blockages uye kugadzirisa kana kutsiva ivo kana zvichidikanwa.
3. Gadzirisa wiring kune sensor kana kutsiva chinongedzo kuti udzorere zvakajairika kushanda.

Yakakomba sei dambudziko rekodhi P0239?

Ipfupi kune simba musensi sensor inogona kukonzera yemukati ECM kupisa, kunyanya kana iyo pfupi yedunhu voltage yakakura kupfuura 5 V.

Kana iyo ECM ichipisa, pane njodzi yekuti mota haizotanga uye inogona kumira.
