Momwe mungayesere sensa ya throttle position ndi multimeter

Chigawo chamagetsi m'dongosolo lanu la jakisoni wamafuta chikalephera, mumayembekezera kuti injini yanu isagwire bwino ntchito.

M'kupita kwa nthawi, ngati mavutowa sanayankhidwe, injini yanu idzavutika, pang'onopang'ono imalephera, ndipo ikhoza kusiya kugwira ntchito palimodzi.

The throttle position sensor ndi chimodzi mwazinthu zoterezi.

Komabe, zizindikiro za TPS yolakwika nthawi zambiri zimakhala zofanana ndi za zida zina zamagetsi zomwe zili ndi vuto, ndipo si anthu ambiri omwe amadziwa momwe angadziwire mavuto.

Bukuli likufotokoza zonse zomwe muyenera kudziwa poyang'ana throttle position sensor, kuphatikizapo zomwe zimachita ku injini ndi momwe mungayesere mwamsanga ndi multimeter.

Tiyeni tiyambe. 

Kodi throttle position sensor ndi chiyani?

Throttle Position Sensor (TPS) ndi gawo lamagetsi mumayendedwe amafuta agalimoto yanu omwe amawongolera kutuluka kwa mpweya kupita ku injini. 

Imayikidwa pamtundu wa throttle ndipo imayang'anira mwachindunji malo a throttle ndikutumiza zizindikiro ku dongosolo la jekeseni wa mafuta kuti zitsimikizire kuti kusakaniza koyenera kwa mpweya ndi mafuta kumaperekedwa ku injini.

Ngati TPS ili yolakwika, mudzakhala ndi zizindikiro zina monga vuto la nthawi yoyatsira moto, kugwiritsa ntchito mafuta ambiri, komanso kusayenda bwino kwa injini, pakati pa ena ambiri.

Multimeter ndi chida chabwino kwambiri chomwe muyenera kuyang'ana zida zamagetsi zagalimoto yanu ndipo zidzakuthandizani mukakumana nazo.

Tsopano tiyeni tiwone momwe tingadziwire throttle position sensor?

Momwe mungayesere sensa ya throttle position ndi multimeter

Khazikitsani ma multimeter kukhala 10 VDC voltage range, ikani kutsogolo kwakuda pa TPS ground terminal ndi red positive lead pa TPS reference voltage terminal. Ngati mita sikuwonetsa 5 volts, TPS ndi yolakwika.

Awa ndi mayeso amodzi okha pamndandanda wa mayeso omwe mumayesa pa throttle position sensor, ndipo tilowa mwatsatanetsatane tsopano. 

1. Konzani phokoso

Musanadumphire mu sensa ya throttle position ndi multimeter, pali njira zingapo zoyambira zomwe muyenera kuchita.

Chimodzi mwa izi ndikuyeretsa thupi la throttle, chifukwa zinyalala zomwe zili pamenepo zimatha kuteteza kuti zisatseguke kapena kutseka bwino. 

Chotsani msonkhano wotsukira mpweya kuchokera ku sensa ya throttle position ndikuyang'ana thupi la throttle ndi makoma a carbon deposits.

Dampen chiguduli chotsuka ndi carburetor ndikupukuta zinyalala zilizonse pomwe muwona zitawunjika.

Pambuyo pochita izi, onetsetsani kuti valve yotsekemera imatsegula ndikutseka mokwanira komanso moyenera.

Yakwana nthawi yoti mupite ku sensa ya throttle position.

Ichi ndi kachipangizo kakang'ono ka pulasitiki kamene kamakhala pambali pa thupi la throttle lomwe lili ndi mawaya atatu osiyana omwe amalumikizana nawo.

Mawaya awa kapena ma tabo olumikizira ndi ofunikira pamayeso athu.

Ngati mukuvutika kupeza mawaya, onani kalozera wathu wamawaya.

Yang'anani mawaya a TPS ndi ma terminals kuti muwone kuwonongeka ndi kuchuluka kwa litsiro. Samalani zonyansa zilizonse ndikupita ku sitepe yotsatira.

2. Pezani throttle position sensor ground 

Kuzindikira kwa malo a Throttle kumatsimikizira ngati pali vuto komanso kumathandizira pakuwunika kotsatira.

Khazikitsani ma multimeter kukhala 20 VDC voltage range, yatsani choyatsira osayambitsa injini, ndiyeno ikani chiwongolero chowoneka bwino chofiira pa batire yagalimoto (yolembedwa "+"). 

Tsopano ikani chiwongolero chakuda chakuda panjira iliyonse ya waya ya TPS kapena ma terminals.

Mumachita izi mpaka wina akuwonetsani kuwerenga kwa 12 volts. Awa ndiye malo anu oyambira ndipo TPS yanu yapambana mayesowa. 

Ngati palibe ma tabo omwe akuwonetsa kuwerenga kwa 12-volt, ndiye kuti TPS yanu siinakhazikike bwino ndipo ingafunike kukonzedwa kapena kusinthidwa kwathunthu.

Ngati yakhazikika, yang'anani tabu yoyambira ndikupitilira sitepe yotsatira.

3. Pezani reference voltage terminal

Galimoto yanu ikadali pamalo oyatsira ndipo ma multimeter akhazikitsidwa ku 10VDC voltage range, ikani waya wakuda pa terminal ya TPS ndikuyika waya wofiyira pazigawo ziwirizo.

Terminal yomwe imakupatsani pafupifupi 5 volts ndi reference voltage terminal.

Ngati simukuwerenga ma volt 5, zikutanthauza kuti pali vuto mudera lanu la TPS ndipo mutha kuwona ngati mawaya ali otayirira kapena achita dzimbiri. 

Kumbali ina, ngati ma multimeter akuwonetsa kuwerengera koyenera, ndiye kuti voliyumu yoyenera ikugwiritsidwa ntchito ku terminal ya TPS.

Siginecha yolumikizira ndi terminal yachitatu yomwe siinayesedwe.

Lumikizani mawaya kumbuyo kwa masensa a throttle position ndikupita ku sitepe yotsatira.

4. Yang'anani mphamvu ya chizindikiro cha TPS 

Kuyesa kwamagetsi amagetsi ndiko kuyesa komaliza komwe kumatsimikizira ngati sensor yanu ya throttle ikugwira ntchito bwino.

Izi zimathandiza kudziwa ngati TPS ikuwerenga molondola phokoso pamene ili lotseguka, lotseguka, kapena lotsekedwa.

Khazikitsani ma multimeter ku 10 VDC voltage range, ikani chiwongolero chakuda chakuda pa terminal ya TPS ndikuwongolera kofiira pamtundu wamagetsi amagetsi.

Zingakhale zovuta kuyika ma multimeter otsogolera pamaterminals popeza TPS yalumikizidwa kale ndi throttle.

Pamenepa, mumagwiritsa ntchito zikhomo kuti mufufuze mawaya (kubayani waya uliwonse wa TPS ndi pini) ndikugwirizanitsa ma multimeter otsogolera ku mapiniwa (makamaka ndi zidutswa za alligator).

Pa throttle throttle, multimeter iyenera kuwerenga pakati pa 0.2 ndi 1.5 volts ngati throttle position sensor ili bwino.

Mtengo wowonetsedwa umatengera mtundu wa TPS yanu.

Ngati multimeter ikuwerenga zero (0), mutha kupitabe ku masitepe otsatirawa.

Pang'onopang'ono tsegulani phokoso ndikuwona kusintha kwa kuwerenga kwa multimeter.

Multimeter yanu ikuyembekezeka kuwonetsa mtengo womwe ukuchulukirachulukira mukamatsegula throttle. 

mbaleyo ikatsegulidwa kwathunthu, multimeter iyeneranso kuwonetsa 5 volts (kapena 3.5 volts pamitundu ina ya TPS). 

TPS ili pamavuto ndipo ikufunika kusinthidwa pamilandu iyi:

• Ngati mtengo umalumpha kwambiri potsegula piritsi.
• Ngati mtengowo ukhala pa nambala kwa nthawi yayitali.
• Ngati mtengo sufika 5 volts pamene throttle ndi lotseguka kwathunthu
• Ngati mtengowo walumpha mosayenera kapena kusinthidwa pogogoda pang'ono sensor ndi screwdriver

Zonsezi ndi malingaliro okhudza TPS, yomwe iyenera kusinthidwa.

Komabe, ngati sensa yanu ya throttle position ndi chitsanzo chosinthika, monga chomwe chimagwiritsidwa ntchito m'magalimoto akale, ndiye kuti pali zambiri zoti muchite musanasankhe kusintha sensor.

Mayendedwe a Variable Throttle Position Sensor

Ma sensor osinthika a throttle position ndi mitundu yomwe mutha kumasula ndikusintha potembenuza kumanzere kapena kumanja.

Ngati TPS yanu yosinthika ikuwonetsa chilichonse mwazizindikiro zomwe tazitchula pamwambapa, mungafune kuzisintha musanasankhe kuzisintha. 

Chinthu choyamba mu izi ndikumasula mabawuti okwera omwe amawateteza ku thupi la throttle. 

Izi zikachitika mudzamvanso ma terminals pomwe TPS ikadali yolumikizidwa ndi throttle.

Lumikizani mayendedwe olakwika a multimeter ku terminal ya TPS ndikuwongolera kolowera ku siginecha.

Ndi kuyatsa ndi kutsekedwa kwatsekedwa, tembenuzirani TPS kumanzere kapena kumanja mpaka mutawerenga bwino mtundu wanu wa TPS.

Mukawerenga zolondola, ingogwirani TPS pamalopo ndikumangitsa mabawuti okwerapo. 

Ngati TPS sinawerengebe bwino, ndiyoyipa ndipo muyenera kuyisintha.

Nayi kanema wamomwe mungasinthire sensa ya throttle position.

Izi zimatengera mtundu wosinthika wa TPS womwe mukugwiritsa ntchito, ndipo ena angafunike dipstick kapena geji kuti musinthe. 

Ma Code Scanner a OBD a Throttle Position Sensor

Kupeza ma code scanner a OBD kuchokera ku injini yanu ndi njira imodzi yosavuta yopezera zovuta za sensor position.

Nawa ma Code atatu a Diagnostic Trouble (DTCs) oti muwayang'anire.

• PO121: Imawonetsa pamene chizindikiro cha TPS sichikugwirizana ndi sensor ya Manifold Absolute Pressure (MAP) ndipo ikhoza kuyambitsidwa ndi sensa ya TPS yosagwira ntchito.
• PO122: Awa ndi magetsi otsika a TPS ndipo amatha chifukwa cha sensor yanu ya TPS kukhala yotseguka kapena kufupikitsidwa pansi.
• PO123: Awa ndi magetsi okwera kwambiri ndipo amatha chifukwa cha malo oyipa a sensa kapena kufupikitsa terminal ya sensor ku terminal yamagetsi.  

Pomaliza

Ndizo zonse zomwe muyenera kudziwa poyang'ana throttle position sensor.

Monga mukuwonera pamasitepe, mtundu kapena mtundu wa TPS womwe mumagwiritsa ntchito umatsimikizira zomwe muyenera kuyang'ana komanso momwe izi zimachitikira. 

Ngakhale mayesowo ndi osavuta, onani katswiri wamakaniko ngati mukukumana ndi mavuto.

Mafunso ofunsidwa kawirikawiri

Kodi ma volts angati ayenera kukhala mu TPS?

Sensa ya throttle position ikuyembekezeka kuwerenga 5V pamene phokoso latsekedwa ndikuwerenga 0.2 ku 1.5V pamene phokoso likutsegulidwa.

Kodi sensa yoyipa ya throttle position imachita chiyani?

Zizindikiro zina za TPS zoyipa zimaphatikizapo kuthamanga kwagalimoto kochepa, ma siginecha oyipa apakompyuta, zovuta zoyatsira nthawi, zovuta zosinthira, kusagwira ntchito movutikira, komanso kuchuluka kwamafuta, pakati pa ena.

Kodi mawaya atatu omwe ali mu sensa ya throttle position ndi chiyani?

Mawaya atatu omwe ali mu sensa ya throttle position ndi waya wapansi, waya wamagetsi wamagetsi, ndi waya wa sensor. Waya wa sensor ndiye chigawo chachikulu chomwe chimatumiza chizindikiro choyenera ku dongosolo la jekeseni wamafuta.
