Indlela yokuhlola inzwa ye-throttle position nge-multimeter

Uma ingxenye kagesi ohlelweni lwakho lomjovo kaphethiloli ihluleka, ngokuqinisekile ulindele ukuthi injini yakho isebenze kabi.

Ngokuhamba kwesikhathi, uma lezi zinkinga zingalungiswa, injini yakho izohlupheka, kancane kancane ihluleke, futhi ingase iyeke ukusebenza ngokuphelele.

Inzwa ye-throttle position ingenye yezingxenye ezinjalo.

Kodwa-ke, izimpawu ze-TPS enephutha ngokuvamile zifana nalezo zezinye izingxenye zikagesi ezinephutha, futhi ababaningi abantu abakwaziyo ukuxilonga izinkinga ngayo.

Lo mhlahlandlela uchaza konke okudingeka ukwazi mayelana nokuhlola inzwa ye-throttle position, okuhlanganisa ukuthi yenzani enjini kanye nendlela yokuhlola okusheshayo nge-multimeter.

Ake siqale. 

Iyini inzwa ye-throttle position?

I-Throttle Position Sensor (TPS) iyingxenye kagesi ohlelweni lokuphatha uphethiloli lwemoto yakho olulawula ukugeleza komoya enjinini. 

Ifakwe ku-throttle body futhi iqaphe ngokuqondile indawo yokudonsa futhi ithumela amasignali ohlelweni lomjovo wamafutha ukuze kuqinisekiswe ukuthi ingxube efanele yomoya kanye nophethiloli inikezwa injini.

Uma i-TPS inephutha, uzobhekana nezimpawu ezithile ezifana nezinkinga zesikhathi sokuvutha, ukukhuphuka kokusetshenziswa kukaphethiloli, nokungenzi kahle kwenjini, phakathi kwezinye eziningi.

I-multimeter iyithuluzi elihle olidingayo ukuze uhlole izingxenye zikagesi zemoto yakho futhi izoba usizo uma ungena kunoma iyiphi yazo.

Manje ake sibone ukuthi ungayixilonga kanjani inzwa yokuma kwe-throttle?

Indlela yokuhlola inzwa ye-throttle position nge-multimeter

Setha i-multimeter kububanzi be-voltage engu-10 VDC, beka i-legative lead emnyama kutheminali ephansi ye-TPS kanye nelead ebomvu ephozithivu kutheminali kagesi eyireferensi ye-TPS. Uma imitha ingabonisi ama-volts angu-5, i-TPS inephutha.

Lokhu ukuhlola okukodwa nje ochungechungeni lwezivivinyo ozisebenzisayo kunzwa ye-throttle position, futhi sizongena emininingwaneni manje. 

1. Hlanza i-throttle

Ngaphambi kokungena kwinzwa ye-throttle position nge-multimeter, kunezinyathelo ezimbalwa zokuqala okufanele uzithathe.

Okunye kwalokhu ukuhlanza umzimba we-throttle, njengoba udoti kuwo ungawuvimbela ukuba ungavuleki noma uvaleke kahle. 

Nqamula umhlangano wokuhlanza umoya kusuka kunzwa ye-throttle position bese uhlola umzimba we-throttle nezindonga ukuze uthole amadiphozithi ekhabhoni.

Dampen iragi ngesicoci se-carburetor bese usula noma iyiphi imfucumfucu lapho uyibona khona.

Ngemuva kokwenza lokhu, qiniseka ukuthi i-valve ye-throttle ivula futhi ivale ngokugcwele nangokufanele.

Isikhathi sokudlulela kunzwa yokuma kwe-throttle.

Lena idivayisi yepulasitiki encane etholakala ohlangothini lwe-throttle body enezintambo ezintathu ezihlukene ezixhunywe kuyo.

Lezi zintambo noma izixhumi zamathebhu zibalulekile ekuhlolweni kwethu.

Uma unenkinga yokuthola izintambo, hlola umhlahlandlela wethu wokulandelela izintambo.

Hlola izintambo ze-TPS namatheminali ngomonakalo nokunqwabelana kokungcola. Nakekela noma yikuphi ukungcola futhi uqhubekele esinyathelweni esilandelayo.

2. Thola indawo yenzwa ye-throttle position 

Ukuthola indawo ye-Throttle position kunquma uma kunenkinga futhi kusiza nokuhlola okulandelayo.

Setha i-multimeter kububanzi be-voltage ye-VDC engu-20, uvule okomlilo ngaphandle kokuqala injini, bese ubeka umthofu obomvu wokuhlola ophozithivu endaweni ephozithivu yebhethri yemoto (ephawulwe ngokuthi "+"). 

Manje beka isivivinyo esinegethivu esimnyama kumzila ngamunye wezintambo ze-TPS noma amatheminali.

Wenza lokhu kuze kube yilapho umuntu ekubonisa ukufundwa kwama-volts angu-12. Lena itheminali yakho yaphansi futhi i-TPS yakho isiphumelele lesi sivivinyo. 

Uma engekho amathebhu abonisa ukufundwa kwe-volt engu-12, khona-ke i-TPS yakho ayigxilile kahle futhi ingase idinge ukulungiswa noma ukushintshwa ngokuphelele.

Uma isekelwe phansi, hlola ithebhu yokuqalisa bese uqhubekela esinyathelweni esilandelayo.

3. Thola i-terminal voltage yereferensi

Njengoba ukuthungela kwemoto yakho kusendaweni kanye ne-multimeter isethwe kububanzi bamandla kagesi angu-10VDC, beka intambo emnyama kutheminali ephansi ye-TPS bese ubeka intambo ebomvu kumatheminali amabili.

Itheminali ekunika cishe ama-volts angu-5 yi-reference voltage terminal.

Uma ungakutholi ukufundwa kwe-volt engu-5, kusho ukuthi kunenkinga kusekethe yakho ye-TPS futhi ungabheka ukuthi izintambo zikhululekile noma zigqwalile. 

Ngakolunye uhlangothi, uma i-multimeter ifundeka ngendlela efanele, khona-ke i-voltage yereferensi efanele isetshenziswa esikhumulweni sesignali se-TPS.

Itheminali yokusayina iyitheminali yesithathu engakaze ihlolwe.

Xhuma izintambo emuva kuzinzwa zokuma kwe-throttle bese uqhubekela esinyathelweni esilandelayo.

4. Hlola i-TPS signal voltage 

Ukuhlolwa kwe-voltage yesignali ukuhlolwa kokugcina okunquma ukuthi inzwa yakho ye-throttle position isebenza kahle yini.

Lokhu kusiza ukuxilonga uma ngabe i-TPS ifunda ngokunembile i-throttle lapho ivuleke ngokugcwele, ivuleke ingxenye, noma ivaliwe.

Setha i-multimeter kububanzi be-voltage engu-10 VDC, beka i-lead yokuhlola emnyama kutheminali ephansi ye-TPS kanye ne-red test lead kutheminali ye-voltage yesiginali.

Kungase kube nzima ukubeka umkhondo we-multimeter kumatheminali njengoba i-TPS isivele ixhunywe kabusha ku-throttle.

Kulesi simo, usebenzisa izikhonkwane ukuze uhlehlise izintambo (ubhoboze intambo ngayinye ye-TPS ngephini) futhi unamathisele umkhondo we-multimeter kulawa maphini (okungcono ngeziqeshana zengwenya).

Ku-throttle ebanzi, i-multimeter kufanele ifunde phakathi kuka-0.2 no-1.5 volts uma inzwa ye-throttle position isesimweni esihle.

Inani elibonisiwe lincike kumodeli ye-TPS yakho.

Uma i-multimeter ifunda uziro (0), usengaqhubekela ezinyathelweni ezilandelayo.

Vula kancane kancane i-throttle futhi ubuke ukushintsha kokufunda kwe-multimeter.

I-multimeter yakho kulindeleke ukuthi ibonise inani elikhula njalo njengoba uvula i-throttle. 

Uma ipuleti livuliwe ngokugcwele, i-multimeter kufanele futhi ibonise ama-volts angu-5 (noma ama-volts angu-3.5 kwamanye amamodeli e-TPS). 

I-TPS isesimweni esibi futhi idinga ukushintshwa kulezi zimo ezilandelayo:

• Uma inani leqa kakhulu lapho uvula ithebhulethi.
• Uma inani libhajwa enombolweni isikhathi eside.
• Uma inani lingafinyeleli ku-5 volts lapho i-throttle ivuliwe ngokugcwele
• Uma inani leqiwe ngokungafanele noma lishintshwe ngokuthepha kancane inzwa nge-screwdriver

Konke lokhu kuyimibono nge-TPS, edinga ukushintshwa.

Kodwa-ke, uma inzwa yakho ye-throttle position iyimodeli elungisekayo, njengalezo ezisetshenziswa ezimotweni ezindala, khona-ke kuningi okumelwe ukwenze ngaphambi kokuthatha isinqumo sokushintsha inzwa.

Izikhombisi-ndlela zenzwa ye-Throttle Position eguquguqukayo

Izinzwa ze-throttle position ezilungisekayo ziyizinhlobo ongazikhulula futhi uzilungise ngokuziphendulela kwesokunxele noma kwesokudla.

Uma i-TPS yakho elungisekayo ibonisa noma yiziphi izimpawu ezishiwo ngenhla, ungase ufune ukuyilungisa ngaphambi kokuthatha isinqumo sokuyishintsha. 

Isinyathelo sokuqala kulokhu ukukhulula amabhawodi akhuphukayo avikela umzimba we-throttle. 

Uma lokhu sekwenziwe uzozizwa amatheminali futhi njengoba i-TPS isaxhunywe ku-throttle.

Xhuma ukuhola okunegethivu kwe-multimeter kutheminali yaphansi ye-TPS kanye nomthofu ophozithivu kutheminali yesiginali.

Uma ukuvutha kuvuliwe kanye ne-throttle ivaliwe, vula i-TPS kwesokunxele noma kwesokudla uze uthole ukufundwa okulungile kwemodeli yakho ye-TPS.

Uma uthola ukufundwa okulungile, vele ubambe i-TPS kulesi simo bese uqinisa amabhawudi akhuphukayo kuyo. 

Uma i-TPS ingafundi kahle, yimbi futhi udinga ukuyishintsha.

Nansi ividiyo yokuthi ungayilungisa kanjani inzwa yokuma kwe-throttle.

Le nqubo incike kumodeli ye-TPS elungisekayo oyisebenzisayo, futhi enye ingase idinge i-dipstick noma igeji ukuze wenze izinguquko. 

I-OBD Scanner Amakhodi we-Throttle Position Sensor

Ukuthola amakhodi esikena se-OBD enjinini yakho kungenye yezindlela ezilula zokuthola izinkinga zenzwa ye-throttle position.

Nawa Amakhodi Enkinga Yokuxilonga (DTCs) amathathu okufanele uwabheke.

• I-PO121: Ibonisa lapho isignali ye-TPS ingahambisani nenzwa ye-Manifold Absolute Pressure (MAP) futhi ingase ibangwe inzwa ye-TPS engasebenzi kahle.
• I-PO122: Lena i-voltage ye-TPS ephansi futhi ingabangelwa itheminali yakho yenzwa ye-TPS ivuliwe noma ifinyelelwe phansi.
• I-PO123: Lena i-voltage ephezulu futhi ingabangelwa indawo yenzwa embi noma ukufinyeza itheminali yezinzwa kutheminali ye-voltage eyireferensi.  

isiphetho

Yilokho kuphela okudingeka ukwazi mayelana nokuhlola inzwa ye-throttle position.

Njengoba ubona ezinyathelweni, imodeli noma uhlobo lwe-TPS oyisebenzisayo inquma ukuthi yini okufanele uyihlole nokuthi lezi zinqubo zenziwa kanjani. 

Nakuba izivivinyo zilula, bona umakhenikha onguchwepheshe uma uba nezinkinga.

Imibuzo evame ukubuzwa

Mangaki amavolthi okufanele abe ku-TPS?

Inzwa ye-throttle position kulindeleke ukuthi ifunde i-5V lapho i-throttle ivaliwe futhi ifunde i-0.2 kuya ku-1.5V lapho i-throttle ivuliwe.

Yenzani inzwa ye-throttle position embi?

Ezinye izimpawu ze-TPS embi zifaka isivinini esilinganiselwe semoto, amasignali amakhompuyutha amabi, izinkinga zesikhathi sokuvutha, izinkinga zokushintsha, ukungenzi lutho, kanye nokusetshenziswa kukaphethiloli okwandisiwe, phakathi kokunye.

Yiziphi izintambo ezi-3 ku-throttle position sensor?

Izintambo ezintathu ku-throttle position sensor yintambo yaphansi, intambo yereferensi kagesi, kanye nentambo yenzwa. Intambo yenzwa iyingxenye eyinhloko ethumela isignali efanele ohlelweni lomjovo kaphethiloli.
