P0451 Evaporator Emission System Pressure Sensor Performance

P0451 - OBD-II Mavuto Code Kufotokozera

Evaporative Emission Control Pressure Sensor Range/Performance

Kodi cholakwika chimatanthauza chiyani P0451?

Code P0451 - "Evaporative Emission System Pressure Sensor/Switch"

Code P0451 imayambika pamene powertrain control module (PCM) ya galimoto imazindikira chizindikiro cholondola kapena chosakhazikika cha voteji kuchokera ku evaporative emission control system pressure sensor.

The evaporative emissions control system (EVAP) idapangidwa kuti igwire ndikusamalira nthunzi yamafuta kuti isalowe mumlengalenga. Code P0451 ikuwonetsa zovuta ndi sensor yokakamiza mu dongosolo lino.

Zifukwa zotheka:

1. Sensor yolakwika ya EVAP.
2. Waya wowonongeka kapena cholumikizira chamagetsi cholumikizidwa ndi sensor sensor.
3. Mavuto ndi dongosolo la EVAP, monga kutayikira kapena kutsekeka.
4. Kuchita kolakwika kwa PCM kapena mavuto ena amagetsi.

Ndibwino kuti mulumikizane ndi makanika oyenerera kapena malo ochitira chithandizo kuti mudziwe molondola ndi kukonza chomwe chimayambitsa.

Zotheka

Khodi ya P0451 ikhoza kukhazikitsidwa pazifukwa izi:

• Sensor yolakwika ya EVAP.
• Mafuta otayira kapena osowa.
• Valavu yopumira mu tanki yamafuta yatsekedwa.
• Zowonongeka, zowonongeka kapena kutenthedwa ndi mizere ya EVAP.
• Mtsuko wamakala wosweka kapena wosweka.

Zomwe zimachitika kwambiri pazifukwa izi ndi tanki yolakwika yamafuta, malo osinthira matanki amafuta olakwika, sensa yotseguka kapena yofupikitsa kapena yozungulira mu tanki yamafuta.

Kodi zizindikiro za cholakwika ndi chiyani? P0451?

Zizindikiro za nambala ya P0451 zitha kukhala zochepa ndipo zimaphatikizapo izi:

• Nthawi zambiri zokhala ndi code P0451 siziwonetsa zizindikiro.
• Pakhoza kukhala kuchepa pang'ono kwa mafuta ochuluka.
• Kuwala kwa Malfunction Indicator Light (MIL) pagawo lazida kumabwera.

Ngati galimoto yanu yapanga nambala ya P0451, ndiye kuti simudzakumana ndi zovuta zilizonse. Nthawi zambiri, chizindikiro chokhacho chidzakhala chowunikira cha injini pa dashboard yanu yomwe ikubwera. Komabe, kuwonjezera pa chizindikiro ichi, mutha kuwonanso fungo losasangalatsa la petulo lomwe limachokera ku injini, chifukwa cha kutuluka kwa nthunzi yamafuta.

Momwe mungadziwire cholakwika P0451?

Kuzindikira molondola nambala ya P0451 kungakhale kovuta. eni galimoto ambiri amakonda kupatsa ntchito akatswiri ndi kupereka galimoto yawo diagnostics.

Njira yodziwira matenda nthawi zambiri imayamba ndi katswiri kuwerenga ma code omwe amasungidwa mu PCM yagalimoto pogwiritsa ntchito scanner ya OBD-II. Zizindikirozi zimawunikidwa ndipo katswiri amayamba kuwunikanso chilichonse momwe amasungira mu PCM. Nthawi zambiri, pambuyo pa nambala ya P0451, ma code ena okhudzana ndi OBD-II amathanso kuyambika ndikusungidwa.

Kujambulako kukamalizidwa, katswiri amawunika zowona zagalimoto ndi masensa onse ogwirizana ndi ma module.

Kusanthula ndikuzindikira nambala ya P0451 ndizovuta kwambiri ndipo tikulimbikitsidwa kusiyidwa kwa akatswiri. M'malo moyesera kudzifufuza, ndi bwino kupita kwa akatswiri odziwa zambiri.

Pambuyo poyang'ana ndikuzindikiritsa kachidindoyo, katswiri adzayamba ndi kuyang'ana kowonekera, pomwe adzayang'ana mawaya, zolumikizira, ndi mabwalo kuti awonongeke. Zolakwa zomwe zadziwika zitathetsedwa, nambala ya P0451 idzachotsedwa ndipo dongosololi lidzawunikidwanso.

Ngati katswiri akuganiza kuti zonse zili m'dongosolo, adzayang'ananso chiboliboli cha malasha, valavu yotsuka, vacuum ndi ma hoses a nthunzi, ndi zina zonse zomwe zimagwirizana ndi njira yoyendetsera evaporative. Chigawo chilichonse chidzafufuzidwa ndipo, ngati n'koyenera, kukonzedwa. Zizindikirozi zidzachotsedwa ndipo injini idzayang'aniridwanso mpaka vuto la code litathetsedwa.

Chonde dziwani kuti mndandanda watsatanetsatane wamalo ogwirira ntchito pafupi ndi inu mumapezeka pa Mndandanda wa KBB Service Center List.

Mukazindikira nambala ya P0451, zida ndi masitepe otsatirawa angafunike:

• Diagnostic scanner.
• Digital volt/ohmmeter.
• Malo odalirika azidziwitso zagalimoto yanu, monga All Data DIY.
• Makina osuta (mwina).
• Yang'anani mowoneka bwino ma hoses ndi mizere ya EVAP, komanso zida zamagetsi ndi zolumikizira.
• Lembani zambiri zamakhodi ndikuyimitsa data ya chimango.
• Kuyang'ana kuthamanga kwa dongosolo la EVAP pogwiritsa ntchito diagnostic flow (scanner).
• Kuwona EVAP pressure sensor.
• Kuyang'ana mabwalo amagetsi pogwiritsa ntchito DVOM.
• Sinthani mabwalo osweka kapena achidule ngati pakufunika.

Kumbukirani kuti kutsika kapena kutsika kwa EVAP kungapangitse kuti P0451 iwoneke, ndipo ikhoza kuyambitsidwa ndi mavuto amagetsi kapena makina.

Zolakwa za matenda

Kunyalanyaza makhodi ena olakwika

Cholakwika chimodzi chofala mukazindikira nambala ya P0451 ndikunyalanyaza ma code ena ovuta. Ngati pali zovuta ndi dongosolo la evaporative emission control (EVAP), ma code ena okhudzana nawo amatha kuyambitsa, monga P0440, P0442, P0452, ndi zina zotero. Kunyalanyaza ma code owonjezerawa kungapangitse kuti muphonye zidziwitso zofunika ndikusokoneza njira yowunikira.

Kufufuza kosawoneka kwadongosolo la EVAP

Kulakwitsa kwina ndikusayang'ana mawonekedwe a EVAP mokwanira. Nthawi zina vutoli likhoza kuyambitsidwa ndi ma hoses owonongeka, zolumikizira, kapena kutayikira mudongosolo. Kusapatula nthawi yoyang'ana bwinobwino zigawozi kungapangitse kuti zikhale zovuta kuzindikira gwero la vutoli.

Osachita ma diagnostics okwanira

Cholakwikacho chagonanso pa mfundo yakuti diagnostics amangokhala kuwerenga zolakwika zizindikiro ndi m'malo EVAP pressure sensor. Khodi iyi ikhoza kuyambitsidwa ndi zifukwa zosiyanasiyana, ndipo kusintha kosalamulirika kwa sensa popanda kuwunika mozama kungakhale muyeso wosagwira ntchito komanso wokwera mtengo.

Kodi zolakwika ndizovuta bwanji? P0451?

Khodi P0451 ndi imodzi mwama code ochepera kwambiri a OBD-II. Nthawi zambiri chizindikiro chokhacho chodziwika ndi kuwala kwa injini yowunikira yomwe ikubwera pa dashboard yagalimoto yanu. Komabe, ngakhale palibe zizindikiro zoonekeratu, galimoto yanu ikhoza kutulutsa mpweya woipa komanso wosasangalatsa wa petulo ndi fungo. Choncho, n’kofunika kukhala ndi katswiri wodziwa ntchito yoyang’anira galimoto yanu ndi kukonza vutolo pofuna thanzi ndi chitetezo.

Kodi kukonza kungathandize kuthetsa code? P0451?

Kukonzekera kotsatiraku kumafunika kuti muthetse code P0451:

1. Bwezerani kapena konzani sensa ya EVAP ngati ili yolakwika.
2. Yang'anani ndikusintha kapu ya tanki yamafuta ngati isowa kapena yawonongeka.
3. Tsukani kapena sinthani valavu ya tanki yamafuta ngati ili yotsekeka kapena yolakwika.
4. Yang'anani ndikusintha mizere yonse yowonongeka, yowonongeka, kapena yowotchedwa ya EVAP.
5. Kusintha cholozera chosweka kapena chosweka cha kaboni chosefera ngati chawonongeka.

Ndikofunikira kuti kuzindikira ndi kukonza kuchitidwe ndi akatswiri odziwa bwino matenda a P0451 angafunike zida zapadera komanso chidziwitso.

P0451 - Zambiri zokhudzana ndi mtundu

Khodi yamavuto P0451 ndi nambala yokhudzana ndi makina otulutsa mpweya wamagetsi / sensor / switch. Khodi iyi itha kugwiritsidwa ntchito pamitundu yosiyanasiyana yamagalimoto okhala ndi dongosolo la OBD-II. Nawa matanthauzo a P0451 amtundu wina:

1. Chevrolet / GMC: P0451 amatanthauza "Evaporative Emission System Pressure Sensor/Switch". Iyi ndi code yomwe imagwirizanitsidwa ndi evaporative emissions control system.
2. Ford: P0451 imatanthauzidwa ngati "Fuel Tank Pressure Sensor". Khodi iyi ikuwonetsa zovuta za kukakamiza kwa tanki yamafuta.
3. ToyotaP0451 amatanthauza "EVAP System Pressure Sensor Error". Khodi iyi ikugwirizana ndi dongosolo la EVAP ndi kukakamizidwa kwake.
4. Volkswagen/AudiP0451 ikhoza kufotokozedwa ngati "EVAP System Pressure Sensor". Izi ndichifukwa cha dongosolo lowongolera mpweya wa evaporative.
5. Dodge/RamP0451 amatanthauza "EVAP System Pressure Sensor Error". Khodi iyi ikugwirizana ndi dongosolo la EVAP.

Chonde dziwani kuti mafotokozedwe enieni a code akhoza kusiyana pang'ono malinga ndi kupanga ndi chitsanzo cha galimoto inayake, choncho nthawi zonse tikulimbikitsidwa kuti muyang'ane buku la utumiki ndi kukonza galimoto yanu kapena funsani makaniko oyenerera kuti mudziwe zambiri ndi kukonza. .
