I-P2120 Throttle Position Sensor / Shintsha ukungasebenzi kahle kwesekethe

I-P2120 Throttle Position Sensor / Shintsha ukungasebenzi kahle kwesekethe

Idatha ye-OBD-II DTC

Ukungasebenzi kahle kochungechunge lwenzwa yesikhundla se-butterfly valve / pedal / switch "D"

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

I-TPS (i-Throttle Position Sensor) iyi-potentiometer ebekwe emzimbeni we-throttle. Inquma i-angle ye-throttle. Lapho i-throttle ihamba, i-TPS ithumela isignali ku-PCM (Powertrain Control Module). Ngokuvamile inzwa enezintambo ezi-5: ireferensi engu-XNUMXV ukusuka ku-PCM ukuya ku-TPS, isuka ku-PCM iye ku-TPS, kanye nokubuya kwesignali kusuka ku-TPS kuya ku-PCM.

I-TPS ithumela imininingwane yesimo sokuphinda ibuyele ku-PCM ngale yocingo lwesiginali. Lapho i-throttle ivaliwe, isiginali imayelana nama-volts angama-45. Nge-WOT (Wide Open Throttle), i-TPS voltage voltage isondela kuma-volts ama-5 agcwele. Lapho i-PCM ithola i-voltage engaphandle kwebanga elijwayelekile lokusebenza, i-P2120 isethiwe. Uhlamvu "D" lisho isifunda esithile, inzwa, noma indawo yesekethe ethile.

QAPHELA: I-PCM iyazi ukuthi noma yiluphi ushintsho olukhulu endaweni yokuphamba kusho ushintsho oluhambisanayo ekucindezelweni kaningi (MAP). Kwezinye izinhlobo, i-PCM izoqapha i-MAP ne-TPS ngokuqhathanisa. Lokhu kusho ukuthi uma i-PCM ibona ushintsho olukhulu lwamaphesenti esimweni sokuphamba, ilindele ukubona ushintsho oluhambisanayo ekucindezelweni okuningi futhi ngokufanayo. Uma engaluboni lolu shintsho lokuqhathanisa, i-P2120 ingahle isethwe. Lokhu akusebenzi kuwo wonke amamodeli.

izimpawu

Izimpawu ezingaba khona zifaka:

• Ukukhanya kwe-MIL (Inkomba Yokungasebenzi)
• Idile noma umgwaqo omkhulu ukhanyisa kabi
• Ikhwalithi engafanele yokungenzi lutho
• Kungenzeka kungasebenzi
• Mhlawumbe iqala nezitebele

izizathu

Izimbangela ezingaba khona zekhodi ye-P2120 zifaka:

• Stuck mpintsha ukubuya mpintsha
• Corrosion ku MAP noma TPS isixhumi
• Ibhande elihanjiswe ngokungafanele libangela ukugeja
• I-TPS engalungile
• I-PCM engalungile

Izixazululo ezingenzeka

Uma ukwazi ukufinyelela ithuluzi lokuskena, bheka amandla we-TPS nge-KOEO (Engine Off Key). Lapho impintsha ivaliwe, i-voltage kufanele ibe cishe ngama-45 V. Kufanele ikhuphuke kancane kancane ifike kuma-volts angama-4.5-5 njengoba uphusha impintsha. Kwesinye isikhathi, i-oscilloscope kuphela engabamba ama-voltage surges wesiginali ye-TPS. Uma ubona ukwehluleka kumandla wokushanela we-TPS, shintsha i-TPS.

QAPHELA. Ezinye izinzwa ze-TPS zidinga ukushuna kahle. Uma ungazizwa ukhululekile ukusebenzisa i-DVOM (I-Digital Volt Ohmmeter) ukuze usethe i-TPS yakho entsha, ukubheja kwakho okungcono kakhulu ukuyisa imoto yakho esitolo. Uma i-voltage ingeyona i-45V (+ noma -3V noma ngaphezulu) ne-throttle ivaliwe, noma uma ukufundwa kubambekile, nqamula isixhumi se-TPS. Usebenzisa i-KOEO, hlola ireferensi ye-5V kusixhumi nendawo enhle. Ungahlola isekethe yesignali ngokuhambisa intambo ye-fusible phakathi kwesekhethi yaphansi yesixhumi se-TPS kanye nesekhethi yesignali. Uma ukufunda kwe-TPS ethuluzini lokuskena manje kufunda uziro, buyisela i-TPS. Kodwa-ke, uma lokhu kungashintshi ukufundwa ku-zero, hlola ukuvuleka noma okufushane ocingweni lwesignali, futhi uma kungatholakali lutho, sola i-PCM embi. Uma ukukhohliswa kwehhanisi le-TPS kubangela noma yiluphi ushintsho ekungenzini lutho, sola ukuthi i-TPS yimbi.

Izingxoxo ezihlobene ze-DTC

• Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.

Udinga usizo olwengeziwe ngekhodi le-p2120?

Uma usadinga usizo nge-DTC P2120, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
