P0738 - OBD-II Mavuto Code Kufotokozera

TCM Engine Speed ​​​​Linanena bungwe Circuit Low

Kodi cholakwika chimatanthauza chiyani P0738?

Code P0738 ndi nambala yamavuto ya OBD-II yomwe ikuwonetsa vuto ndi sensa yotulutsa liwiro la injini mu Transmission Control Module (TCM). Sensa iyi imayang'anira liwiro la injini ndikutumiza deta ku powertrain control module (PCM), yomwe imagwiritsa ntchito chidziwitsochi kusintha magiya molondola. Nthawi zambiri, liwiro la injini liyenera kusiyanasiyana malinga ndi kuchuluka kwa liwiro lagalimoto kuti zitsimikizire kuti zikuyenda bwino. PCM ikazindikira kuti liwiro la injini likusintha mwachangu kapena osasintha konse, imapanga code P0738. Khodi iyi imathanso kukhazikitsidwa ngati PCM silandira chizindikiro kuchokera ku sensa ya liwiro la injini.

Chithunzi cha module control transmission:

Khodi ya P0738 ndi nambala yapadziko lonse ya OBD-II yomwe imagwira ntchito pamagalimoto osiyanasiyana kuphatikiza Dodge, Chevrolet, Honda, Toyota, Hyundai, Jaguar ndi ena ambiri. Ngakhale kuti code ndi yofala, njira zenizeni zothetsera izo zikhoza kukhala zosiyana malinga ndi galimoto yeniyeni ndi kasinthidwe kake.

Kawirikawiri, P0738 imagwirizanitsidwa ndi mavuto a magetsi, nthawi zambiri kuposa makina. Komabe, njira zenizeni zowunikira ndi kukonza zingafunike ntchito yaukadaulo ndipo zimatha kusiyanasiyana kutengera mtundu wagalimoto.

Zotheka

Zomwe zingayambitse nambala ya P0738 ndi izi:

  1. Sensa yothamanga ya injini yolakwika (ESS).
  2. Zolakwika kufala linanena bungwe liwiro sensa.
  3. Kusakwanira kufala kwamadzimadzi mulingo.
  4. Zakhudzidwa kufala madzimadzi.
  5. Nthawi zina, gawo lowongolera injini (ECM) limakhala lolakwika.
  6. Zida zamagetsi zomwe zili ndi vuto kuphatikiza zingwe, zolumikizira ndi ma fuse.

Khodi ya P0738 imatha kuyambitsidwa ndi zolakwika za Engine Speed ​​​​Sensor (ESS), zolakwika za Engine Control Module (ECM), zolakwika za Transmission Control Module (TCM), zovuta zamawaya, kujambula konyansa pa Engine Speed ​​​​Sensor (ESS). ), kapena zovuta zolumikizira. .

Kodi zizindikiro za cholakwika ndi chiyani? P0738?

Khodi ya P0738 ikawonekera, nthawi zambiri imatsagana ndi izi:

  1. Kusintha zida zolimba.
  2. Kuchepetsa kugwiritsa ntchito mafuta.
  3. Mavuto ndi kuyambitsa injini.
  4. Kuthamanga kwagalimoto kochepa.
  5. Injini imatsika kapena kugwedezeka.
  6. Mawonekedwe olondola a speedometer.
  7. Pang'ono kulabadira throttle.

Zizindikirozi zitha kuwonetsa zovuta zotumizira, kuphatikiza kusuntha kovutirapo, vuto la injini, ndi zovuta zowonetsera ma Speedometer, zomwe zimatha kubweretsa kuchepa kwamafuta.

Momwe mungadziwire cholakwika P0738?

Kuti muzindikire ndikukonza khodi ya P0738, tikulimbikitsidwa kutsatira izi:

  1. Gwiritsani ntchito scanner ya code ya OBD-II kuti muzindikire khodi ya P0738 ndikuwona ma code ena ovuta.
  2. Ngati manambala owonjezera apezeka, yang'anani momwe amawonekera pa sikani ndikuwongolera kuyambira ndi yoyamba.
  3. Mukazindikira, chotsani zizindikiro zamavuto, yambitsaninso galimoto, ndikuwona ngati nambala ya P0738 ikupitilira. Ngati codeyo ichoka mutayambiranso ndikuyambiranso, likhoza kukhala vuto lakanthawi kochepa.
  4. Ngati nambala ya P0738 ipitilira, yang'anani kuchuluka kwa madzimadzi otumizira ndi kutayikira kulikonse. Onjezani madzimadzi ngati mukufunikira ndipo fufuzani mosamala ngati akutuluka. Kutuluka madzimadzi kungayambitse kuwonongeka kwina.
  5. Ngati madzi opatsirana ali odetsedwa, sinthani. Ngati madziwa ali onyansa kwambiri, kachilomboka kangafunike kukonzedwa kapena kusinthidwa.
  6. Chitani kuyang'ana kowonekera kwa zigawo zamagetsi. Sinthani mawaya owonongeka, zolumikizira ndi ma fuse.
  7. Yang'anani ma sensor othamanga, kuwonetsetsa kuti ma siginecha awo ndi ma voliyumu amawunikiridwa amayang'aniridwa.
  8. Pambuyo pokonza khodi ya P0738, chotsani zizindikiro zamavuto ndikuyambitsanso galimoto kuti muwone ngati codeyo ichoka.

Ndikofunikiranso kuganiziranso ma bulletins a technical service (TSBs) agalimoto yanu, chifukwa amatha kukhala ndi chidziwitso chokhudza zovuta zomwe zimadziwika ndi mayankho. Kukonza mabwalo otulutsa liwiro la injini kungafunike zida zapadera monga owerenga ma code a OBD, ma multimeter, ndi zida zama waya. Dziwani zachitetezo ndikuwonetsetsa kukhulupirika kwa batri ndi makina oyitanitsa musanagwiritse ntchito zida zamagetsi.

Zolakwa za matenda

Kulakwitsa kofala kwambiri pakuzindikira nambala ya P0738 sikutsata njira yowunikira zovuta za OBD-II. Ndikofunika kuti akatswiri amatsatira ndondomekoyi nthawi zonse kuti apewe kukonza zolakwika. Kupanda kutero, pamakhala chiwopsezo chakusintha kosafunikira, monga sensor liwiro lagalimoto kapenanso sensa yogwira ntchito bwino. Kuzindikira kuyenera kukhala kosamalitsa komanso kwadongosolo, kuyambira ndikuyang'ana zinthu zoyambira ndikusunthira pang'onopang'ono kuzinthu zovuta kwambiri.

Kodi zolakwika ndizovuta bwanji? P0738?

Khodi yamavuto P0738 ikhoza kukhala yayikulu chifukwa ikuwonetsa vuto ndi kufalitsa kapena chizindikiro cha liwiro la injini. Izi zitha kubweretsa zovuta pakusuntha zida, zomwe pamapeto pake zimabweretsa kusayenda bwino kwagalimoto komanso kuwonongeka komwe kungathe kufalikira. Choncho, pamene code ya P0738 ikuwonekera, ndikofunika kuti mutengepo kanthu kuti muzindikire ndi kukonza vutoli mwamsanga kuti muteteze kuwonongeka kwina ndi kukonzanso kwamtengo wapatali kwa kufalitsa.

Kodi kukonza kungathandize kuthetsa code? P0738?

Kuti muthetse nambala ya P0738, kukonzanso zingapo kumafunika, zomwe zingaphatikizepo:

  1. Kuzindikira: Choyamba muyenera kuchita zoyezetsa kuti mudziwe zomwe zimayambitsa nambala ya P0738. Kuti muchite izi, ma scanner olakwika a OBD-II amagwiritsidwa ntchito.
  2. Kuyang'ana madzimadzi opatsirana: Yang'anani mlingo ndi momwe madzi akutumizira. Ngati madzi amadzimadzi ali otsika kapena oipitsidwa, izi zikhoza kukhala chifukwa cha vutoli ndipo zingafunike kuwonjezera kapena kusintha madziwo.
  3. Kuwona kwa Speed ​​​​Sensor: Yang'anani ma sensor othamanga a shaft pazovuta. M'malo mwake ngati kuli kofunikira.
  4. Engine Speed ​​​​Sensor (ESS) Yang'anani: Yang'anani liwiro la injini pamavuto ndikusintha ngati kuli kofunikira.
  5. Yang'anani zida zamagetsi: Yang'anani mawaya, zolumikizira, ndi ma fuse kuti zawonongeka. M'malo mwake ngati awonongeka.
  6. Kuyeretsa ndi Kusintha kwa Sensor: Nthawi zina, kuyeretsa masensa ndikusintha pambuyo pochotsa zinyalala zilizonse kumatha kuthetsa vutoli.
  7. Kuyang'ana kwa Transmission Control Module (TCM): Yang'anani TCM ngati yawonongeka, yawonongeka, kapena yawonongeka.
  8. Kusintha kwa Mapulogalamu: Nthawi zina, kukonzanso pulogalamu ya TCM kumatha kuthetsa nambala ya P0738.
  9. Yang'anani zolemba zaukadaulo: Yang'anani kuti muwone ngati pali zolemba zaukadaulo (TSBs) zamapangidwe anu ndi mtundu wagalimoto zomwe zingasonyeze zovuta zodziwika ndi mayankho.

Kumbukirani kuti kukonzanso kudzatengera zifukwa zenizeni zomwe nambala ya P0738 idachitikira. Muyenera kuchita zoyezetsa kaye ndikuchita ntchito yoyenera yokonza malinga ndi zovuta zomwe zadziwika.
