Khodi Yovuta ya OBD-II - P0121 Kufotokozera Zaukadaulo

P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Vuto.

DTC P0121 zimachitika pamene injini ulamuliro gawo (ECU, ECM kapena PCM) detects olakwika throttle udindo sensa (TPS - throttle udindo kachipangizo), amatchedwanso potentiometer, amene amatumiza makhalidwe olakwika malinga ndi malamulo.

Kodi vuto la P0121 limatanthauza chiyani?

Izi Diagnostic Trouble Code (DTC) ndi njira yolozera, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II. Ngakhale zambiri, njira zina zakukonzanso zimatha kusiyanasiyana kutengera mtundu / mtundu.

The throttle position sensor ndi potentiometer yomwe imayesa kuchuluka kwa kutsegula kwa throttle. Pamene phokoso likutsegulidwa, kuwerenga (kuyesedwa mu volts) kumawonjezeka.

Gawo lowongolera la powertrain (PCM) limapereka chizindikiritso cha 5V ku Throttle Position Sensor (TPS) ndipo nthawi zambiri chimakhalanso pansi. Muyeso wamba: ulesi = 5V; kupuma kwathunthu = 4.5 volts. Ngati PCM itazindikira kuti mphetoyo ndi yayikulu kapena yocheperako kuposa momwe imayenera kukhalira ndi RPM inayake, ikhazikitsa code iyi.

Zizindikiro zake

Zizindikiro za vuto la P0121 zitha kuphatikiza:

  • Nyali Yazizindikiro Zosagwira (MIL) yowunikiridwa (Yang'anirani Kuunika kwa Injini kapena Injini Yake Posachedwa)
  • Kupunthwa kwakanthawi mukathamangitsa kapena kuthamanga
  • Kuwombera utsi wakuda mukamathamangitsa
  • Osayamba
  • Yatsani nyali yochenjeza ya injini yofananira.
  • Kuwonongeka kwa injini zonse, zomwe zingayambitse moto wolakwika.
  • Mavuto ndi kufulumizitsa zowongolera.
  • Mavuto ndi kuyambitsa injini.
  • Kuchuluka kwamafuta.

Komabe, zizindikilozi zitha kuwonekanso limodzi ndi ma code ena olakwika.

Zifukwa za P0121 kodi

Sensa ya throttle position imagwira ntchito yowunikira ndikuzindikira mbali yotsegulira ya damper iyi. Zomwe zalembedwazo zimatumizidwa ku injini yoyang'anira injini, yomwe imagwiritsa ntchito kuwerengera kuchuluka kwa mafuta ofunikira kuti alowe mu dera kuti akwaniritse kuyaka kwangwiro. Ngati gawo la kuwongolera injini likuwona kusasinthika kwamphamvu chifukwa cha sensor yolakwika, DTC P0121 idzakhazikitsa.

Khodi ya P0121 itha kutanthauza kuti chimodzi kapena zingapo mwazimene zachitika:

  • Kulephera kwa sensa ya Throttle position.
  • Kuwonongeka kwa mawaya chifukwa cha waya wopanda kanthu kapena dera lalifupi.
  • Vuto la ma waya a Throttle position.
  • Kukhalapo kwa chinyezi kapena kulowerera kwakunja komwe kumakhudza ntchito yamagetsi.
  • Zolumikizira zolakwika.
  • Kuwonongeka kwa gawo lowongolera injini, kutumiza ma code olakwika.
  • TPS ili ndi gawo lotseguka lotseguka kapena dera lalifupi lamkati.
  • Chingwecho chikupukutira, ndikupangitsa kuti pakhale njira yotseguka kapena yayifupi mu waya.
  • Kulumikizana kolakwika mu TPS
  • PCM yoyipa (zochepa)
  • Madzi kapena dzimbiri cholumikizira kapena sensa

Mayankho otheka

1. Ngati mutha kugwiritsa ntchito chida chojambulira, onani zomwe ma DVD osavomerezeka (WOT) amawerengedwa pa TPS. Onetsetsani kuti ali pafupi ndi zomwe zanenedwa pamwambapa. Ngati sichoncho, sinthani TPS ndikuyambiranso.

2. Fufuzani kanthawi kotseguka kapena kofupikitsa mu siginecha ya TPS. Simungagwiritse ntchito chida chojambulira izi. Mufunika oscillator. Izi ndichifukwa choti zida zowunikira zimatenga kuwerengera kosiyanasiyana pamizere imodzi yokha kapena iwiri ndipo amatha kuphonya komwe kungachitike. Lumikizani oscilloscope ndikuwona chizindikirocho. Iyenera kukwera ndi kugwa bwino, osatuluka kapena kutuluka.

3. Ngati palibe vuto lomwe likupezeka, yesani mayeso osokonekera. Chitani izi mwakugwedeza cholumikizira ndikulumikiza poyang'ana ndondomekoyi. Akutsikira? Ngati ndi choncho, sinthani TPS ndikuyambiranso.

4. Ngati mulibe chizindikiro cha TPS, yang'anani za 5V yolumikizira cholumikizira. Ngati alipo, yesani dera loyandikana ndi dera lotseguka kapena lalifupi.

5. Onetsetsani kuti dera lazizindikiro silili 12V.Lisakhale ndi magetsi a batri. Ngati ndi choncho, tsatirani dera lanu kwa kanthawi kochepa mpaka magetsi ndikukonzekera.

6. Fufuzani madzi cholumikizira ndi m'malo mwa TPS ngati kuli kofunikira.

Zida zina za TPS ndi DTCs za Dera: P0120, P0122, P0123, P0124

Kukonza Malangizo

Galimoto ikatengedwera ku msonkhano, makaniko nthawi zambiri amachita izi kuti azindikire vutolo:

  • Jambulani manambala olakwika ndi sikani yoyenera ya OBC-II. Izi zikachitika ndipo ma code akasinthidwa, tidzapitiriza kuyesa galimoto pamsewu kuti tiwone ngati zizindikirozo zikuwonekeranso.
  • Kuyang'ana throttle position sensor.
  • Kuyang'ana kwa zigawo za dongosolo la chingwe.
  • Kuwunika kwa valve ya Throttle.
  • Kuyeza kukana kwa sensa ndi chida choyenera.
  • Kuyang'ana zolumikizira.

Kusintha kwachangu kwa throttle sensor sikuvomerezeka, chifukwa chifukwa cha P0121 DTC chikhoza kugona mu chinthu china, monga dera lalifupi kapena zolumikizira zoipa.

Nthawi zambiri, kukonza komwe nthawi zambiri kumayeretsa code iyi ndi motere:

  • Konzani kapena sinthani sensor position.
  • Kukonza kapena kusintha zolumikizira.
  • Kukonza kapena kusintha ma waya amagetsi olakwika.

Kuyendetsa ndi zolakwika P0121 sikuvomerezeka, chifukwa izi zingakhudze kwambiri kukhazikika kwa galimoto pamsewu. Pachifukwa ichi, muyenera kutengera galimoto yanu kumalo ogwirira ntchito mwamsanga. Poganizira zovuta zamawunikidwe omwe akuchitika, njira ya DIY mu garaja yakunyumba mwatsoka siyingatheke.

N'zovuta kulingalira ndalama zomwe zikubwera, chifukwa zambiri zimadalira zotsatira za matenda omwe amachitidwa ndi makaniko. Nthawi zambiri, mtengo wokonza thupi lopumira mumsonkhano ukhoza kupitilira ma euro 300.
