P2120 Fulumizitsa Udindo SENSOR / Sinthani C Kuyenda Kwadongosolo

Mapepala a OBD-II DTC

Kulephera kwa unyolo wa sensa ya udindo wa gulugufe / pedal / lophimba "D"

Kodi izi zikutanthauzanji?

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.

TPS (Throttle Position Sensor) ndi potentiometer yomwe imayikidwa pa throttle body. Zimatsimikizira mbali ya throttle. Pamene phokoso likuyenda, TPS imatumiza chizindikiro ku PCM (Powertrain Control Module). Nthawi zambiri sensa ya mawaya atatu: 5V yotchulidwa kuchokera ku PCM kupita ku TPS, pansi kuchokera ku PCM kupita ku TPS, ndi kubwereranso kwa chizindikiro kuchokera ku TPS kupita ku PCM.

TPS imatumiza zidziwitso za throttle position kubwerera ku PCM pa waya wama sigino. Pamene throttle yatsekedwa, chizindikirocho chimakhala pafupifupi 45 volts. Ndi WOT (Wide Open Throttle), mphamvu yamagetsi ya TPS imayandikira ma volts 5 athunthu. PCM ikazindikira voteji kunja kwanthawi zonse, P2120 imayikidwa. Chilembo "D" chimatanthawuza dera linalake, sensa, kapena gawo la dera linalake.

ZOYENERA: PCM imadziwa kuti kusintha kulikonse kwakukulu pamakhalidwe kumatanthauza kusintha komwe kumafanana (MAP). Pa mitundu ina, PCM imayang'anira MAP ndi TPS poyerekeza. Izi zikutanthauza kuti ngati PCM ikawona kuchuluka kwakukulu pakusintha, ikuyembekeza kuwona kusintha kofananako pamavuto osiyanasiyana komanso mosemphanitsa. Ngati sawona kusintha uku, P2120 ikhoza kukhazikitsidwa. Izi sizikugwira ntchito pamitundu yonse.

Zizindikiro

Zizindikiro zina monga:

• Kuunikira kwa MIL (Chizindikiro Chosagwira)
• Imawayatsa kapena kuyatsa misewu yayikulu
• Mkhalidwe wopanda ntchito
• Musakhale aulesi
• Mwinamwake akuyamba ndi masheya

zifukwa

Zomwe zingayambitse kachidindo ka P2120 ndi izi:

• Kasupe wobwerera wopumira
• Dzimbiri pa MAP kapena TPS chojambulira
• Lamba loyendetsedwa molakwika limayambitsa chafing
• TPS Yoipa
• PCM yoyipa

Mayankho otheka

Ngati mutha kugwiritsa ntchito chida chowonera, yang'anani magetsi a TPS ndi KOEO (Engine Off Key). Ndi kukhazikika kotsekedwa, voliyumu iyenera kukhala pafupifupi 45 V. Iyenera kukwera pang'onopang'ono mpaka pafupifupi 4.5-5 volts mukamakankhira. Nthawi zina, ndi oscilloscope yokha yomwe imatha kutenga ma voltage okwera nthawi ndi nthawi a chizindikiro cha TPS. Mukawona kulephera kwa magetsi a TPS, tengani TPS.

ZINDIKIRANI. Masensa ena a TPS amafunikira kukonza bwino. Ngati simukumva bwino kugwiritsa ntchito DVOM (Digital Volt Ohmmeter) kuti mukhazikitse TPS yanu yatsopano, mwayi wanu wabwino kwambiri ndikutengera galimoto yanu kushopu. Ngati voteji si 45V (+ kapena -3V kapena choncho) ndi throttle chatsekedwa, kapena ngati kuwerenga anakakamira, kusagwirizana TPS cholumikizira. Pogwiritsa ntchito KOEO, fufuzani za 5V pa cholumikizira ndi malo abwino. Mutha kuyesa mawonekedwe azizindikiro posuntha waya wa fusible pakati pa gawo lapansi la cholumikizira cha TPS ndi dera lazizindikiro. Ngati kuwerenga kwa TPS pa chida chojambulira tsopano kukuwerenga zero, sinthani TPS. Komabe, ngati izi sizikusintha kuwerengera kukhala ziro, fufuzani kuti pali chotseguka kapena chachifupi mu waya wamakina, ndipo ngati palibe chomwe chikupezeka, ganizirani PCM yoyipa. Ngati kusintha kwa harni ya TPS kumayambitsa kusintha kulikonse, ganizirani kuti TPS ndiyoyipa.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi nambala yanu ya p2120?

Ngati mukufunabe thandizo ndi DTC P2120, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
