P1157 (Volkswagen, Audi, Skoda, Mpando) Manifold absolute pressure (MAP) sensor - supply voltage

P1157 - OBD-II Mavuto Code Kufotokozera

Khodi yamavuto P1156 ikuwonetsa vuto ndi mphamvu yamagetsi yamagetsi amtundu wa manifold absolute pressure (MAP) mu Volkswagen, Audi, Skoda, Seat magalimoto.

Kodi cholakwika chimatanthauza chiyani P1157?

Khodi yamavuto P1157 ikuwonetsa vuto ndi manifold absolute absolute pressure (MAP) sensor power circuit. Sensa iyi imayang'anira kuyeza kuthamanga kwa mpweya m'njira zambiri ndikutumiza zidziwitso zofananira ku gawo lowongolera injini (ECM). Mphamvu yamagetsi ya sensa iyi ndi yosiyana ndi yomwe ikuyembekezeredwa, kusonyeza vuto lomwe lingakhalepo ndi ntchito yake kapena dera lamagetsi lomwe limayipatsa mphamvu.

Zotheka

Zina mwazifukwa za vuto la P1157:

• Kulephera kwa sensor ya MAP: Sensor ya MAP yokha ikhoza kuonongeka, kusagwira ntchito bwino, kapena kuwerenga molakwika chifukwa cha kuvala kwakuthupi, kuwononga, kuzungulira kotseguka, kapena zifukwa zina.
• Mavuto amagetsi: Zolakwika mu mawaya, zolumikizira, kapena zolumikizira zomwe zimapereka mphamvu ku sensa ya MAP zitha kupangitsa kuti magetsi azikhala olakwika kapena afupikitsidwe pansi, zomwe zimapangitsa P1157 code.
• Mavuto ndi gawo lowongolera injini (ECM): Zolakwika mu gawo lowongolera injini, lomwe limalandira deta kuchokera ku sensa ya MAP ndikuyendetsa ntchito yake, lingayambitsenso P1157 code.
• Mavuto ndi vacuum system: Kutayikira kapena mavuto mu vacuum system, yomwe imagwiritsidwa ntchito ndi MAP sensor kuyeza kupanikizika, imatha kuyambitsa kuwerenga kolakwika ndi cholakwika.
• Mavuto ndi dongosolo lamadyedwe: Dongosolo lolowera lotsekeka kapena lowonongeka, kuphatikiza fyuluta yotsekeka ya mpweya kapena kuchuluka kwamafuta odzaza mafuta, imathanso kukhudza magwiridwe antchito a MAP ndikuyambitsa P1157.

Zomwe zimayambitsa izi nthawi zambiri zimafunikira kuwunika kowonjezera kuti muzindikire molondola ndi kukonza vutolo.

Kodi zizindikiro za cholakwika ndi chiyani? P1157?

Ndi DTC P1157, mutha kukumana ndi izi:

• Kutaya mphamvu: Sensa yosagwira ntchito kapena yosagwira bwino ntchito (MAP) imatha kuwononga mphamvu ya injini. Izi zitha kuwonekera poyankha pang'onopang'ono kumayendedwe a gasi komanso kuthamangitsa koyipa kwambiri.
• Magwiridwe a injini osakhazikika: Kuwerenga kolakwika kwa sensa ya MAP kungayambitse kusakhazikika kwa injini. Izi zitha kuwoneka mwakuchita movutikira, kunjenjemera, kapena ngakhale kuwotcha mwachisawawa.
• Kuchuluka mafuta: Kugwiritsira ntchito molakwika kwa MAP sensor kungayambitse kusakaniza kolakwika kwa mafuta / mpweya, komwe kungayambitse kuwonjezereka kwa mafuta.
• Kuchuluka kwa mpweya woipa wa zinthu: Ngati mafuta/mpweya osakaniza achuluka (mafuta ochuluka kwambiri), angayambitse kutulutsa kwazinthu zovulaza monga ma hydrocarbon ndi ma nitrogen oxide.
• Zolakwika za kasamalidwe ka injini (Chongani Injini): Khodi ya P1157 ikawonekera, nthawi zambiri imatsagana ndi Kuwala kwa Injini Yoyang'ana kuyatsa dashboard yagalimoto yanu.

Momwe mungadziwire cholakwika P1157?

Njira zotsatirazi zikulimbikitsidwa kuti muzindikire DTC P1157:

1. Kuyang'ana khodi yolakwika: Pogwiritsa ntchito chida chojambulira, werengani kachidindo ka P1157 kuchokera ku Engine Control Module (ECM) ndikujambula kuti muwunikenso pambuyo pake.
2. Kuyang'ana kowoneka kwa sensa ya MAP ndi kulumikizana kwake: Yang'anani kachipangizo kakang'ono kwambiri (MAP) ndi maulumikizidwe ake amagetsi kuti muwone kuwonongeka, dzimbiri, kapena kusalumikizana bwino. Onetsetsani kuti zolumikizira zili zolumikizidwa bwino.
3. Kuyeza MAP Sensor Supply Voltage: Pogwiritsa ntchito ma multimeter, yesani mphamvu zamagetsi pazikhomo zofananira za sensa ya MAP. Onetsetsani kuti mphamvu yamagetsi ikugwirizana ndi zomwe wopanga galimotoyo akufuna.
4. MAP Sensor Circuit Resistance Test: Yesani kukana kwa sensa ya MAP kuti muwonetsetse kuti ili mkati mwazomwe zatchulidwa. Zolakwika zimatha kuwonetsa zovuta mudera kapena sensa yokha.
5. Zotsatira za ECM: Ngati n'koyenera, kuchita diagnostics zina pa injini ulamuliro gawo (ECM) kuchotsa zotheka injini malfunctions.
6. Kuyesa kwa vacuum system: Onani ma vacuum hoses ndi mavavu kuti akudontha kapena kuwonongeka chifukwa izi zitha kukhudza magwiridwe antchito a MAP.
7. Kuchita zoyezetsa matenda: Gwiritsani ntchito zida zapadera ndi mapulogalamu kuti muyese mayeso owonjezera, monga kuyezetsa nthawi yeniyeni kapena zowunikira.

Kuti muzindikire bwino vuto la code ya P1157, ndikofunikira kulingalira magwero onse amavuto ndikutsatira malangizo a akatswiri ndi malingaliro opanga magalimoto.

Zolakwa za matenda

Mukazindikira DTC P1157, zolakwika zotsatirazi zitha kuchitika:

• Kudumpha kuyang'ana kowoneka: Akatswiri ena amatha kulumpha kuyang'ana kowoneka kwa MAP sensor ndi maulumikizidwe ake, zomwe zingayambitse kusowa kwa zovuta zoonekeratu monga kuwonongeka kapena dzimbiri.
• Kuwunika kosakwanira kwa kugwirizana kwa magetsi: Kuyang'ana zolumikizira zakunja zokha popanda kuyang'ana kulumikizana kwabwino komanso momwe mawaya alili kungayambitse vuto lamagetsi.
• Kunyalanyaza zomwe opanga amapanga: Kulephera kutsatira zomwe wopanga amapangira mphamvu yamagetsi yamagetsi ya MAP kapena kukana kungayambitse matenda olakwika.
• Zolakwika pakutanthauzira deta ya scanner: Kutanthauzira molakwika kwa data yomwe idalandilidwa kuchokera ku scanner yowunikira kungayambitse kuzindikirika molakwika ndi kusazindikirika bwino kwa vutolo.
• Kuzindikira molakwika zigawo zina: Nthawi zina akatswiri amatha kuyang'ana pa sensa ya MAP kwinaku akunyalanyaza zomwe zingayambitse, monga zovuta ndi gawo lowongolera injini (ECM), vacuum system, kapena njira yolowera.
• Kukonza vuto molakwika: Ngati vuto la P1157 silinadziwike bwino, kuthetsa kwake kungakhale kosakwanira kapena kosagwira ntchito, zomwe zingapangitse kuti cholakwikacho chibwerenso.

Kodi zolakwika ndizovuta bwanji? P1157?

Khodi yamavuto P1157 siyofunika kwambiri pakuyendetsa galimoto, koma ikuwonetsa zovuta zamakina oyang'anira injini zomwe zingayambitse kusagwira bwino ntchito, kugwiritsa ntchito mafuta ambiri, komanso kuchuluka kwa mpweya. Kusakaniza kwamafuta / mpweya kolakwika komwe kumachitika chifukwa cha kupanikizika kokwanira kokwanira kokwanira (MAP) kumatha kuchititsa kuti injini iwonongeke komanso kuthamanga kwamphamvu. Choncho, tikulimbikitsidwa kuti mulumikizane ndi katswiri kuti muzindikire ndi kukonza vutoli mwamsanga kuti mupewe kuwonongeka kowonjezera ndi kuwonongeka kwa kayendetsedwe ka galimoto.

Kodi kukonza kungathandize kuthetsa code? P1157?

Kuthetsa vuto P1157 nthawi zambiri kumafuna izi:

1. Manifold Absolute Pressure (MAP) Sensor Replacement: Ngati sensa ya MAP ilidi yolakwika kapena chizindikiro chake sichikuperekedwa bwino ku Engine Control Module (ECM), ndiye kuti m'malo mwa sensayo iyenera kukonza vutoli.
2. Kuwunika kwamagetsi: Ngati vutoli likukhudzana ndi dera lamagetsi, muyenera kuyang'ana mawaya ndi zolumikizira zowonongeka, zowonongeka kapena zosayenera. Ngati ndi kotheka, konzani kapena kusintha zigawo zowonongeka.
3. Engine Control Module (ECM) Kuzindikira: Nthawi zina, vuto likhoza kukhala chifukwa cha kusokonekera kwa gawo lowongolera injini lokha. Ngati zifukwa zina zachotsedwa, zingakhale zofunikira kuti mupitirize kufufuza ECM ndipo, ngati kuli kofunikira, m'malo mwake.
4. Kuwona vacuum system: Kutayikira mu vacuum system kungapangitse sensor ya MAP kuti iwerenge molakwika. Yang'anani mipaipi ya vacuum ndi mavavu ngati akudontha ndikusintha kapena kukonzanso ngati kuli kofunikira.
5. Engine Control Module (ECM) Firmware: Nthawi zina kukonzanso pulogalamu ya module control injini kungathandize kuthetsa ma code amavuto kuphatikiza P1157.

Mukamaliza masitepewa, tikulimbikitsidwa kuyesa dongosolo ndikuchotsa zolakwika pogwiritsa ntchito scanner yowunikira. Ngati vutoli likupitirira, kufufuza kwina kapena kukambirana ndi akatswiri kungafunike.
