NZIRA YOKUEDZA O2 SENSOR NEMULTIMETER
Zviri mukati
Pasina tsananguro, injini yemotokari yako haina kusimba uye pamwe ndiyo inonyanya kukosha yemotokari yako.
Kune akawanda masensa anoita kuti ishande mumamiriro akanyanya kunaka, uye kana imwe yadzo ikatadza, injini iri munjodzi.
Une matambudziko einjini here?
Wakambomhanyisa bvunzo pane anonyanya kufarirwa sensors senge crankshaft sensor kana throttle chinzvimbo sensor uye uchiri kumhanya mudambudziko rimwe chete?
Ipapo iyo O2 sensor inogona kunge iri iyo isinganyanyo kufarirwa mhosva.
Mune ino positi, tichakufambisa iwe mukati memaitiro ese ekutarisa maO2 sensors, kubva pakunzwisisa zvavari kusvika pakushandisa multimeter kugadzira akasiyana siyana.
Ngatitangei.
Chii chinonzi O2 sensor?
An O2 sensor kana oxygen sensor chinhu chemagetsi chinoyera huwandu hweokisijeni mumhepo kana mvura yakaipoteredza.
Kana zvasvika kumotokari, iyo okisijeni sensor chishandiso chinobatsira injini kudzora chiyero chemhepo kuhuni.
Inowanikwa munzvimbo mbiri; kungave pakati pekupedza manifold uye catalytic converter, kana pakati pecatalytic converter uye exhaust port.
Mhando yakajairika yeO2 sensor inoshandiswa mumotokari ndeye wideband zirconia sensor, ine waya ina dzakabatana nayo.
Waya idzi dzinosanganisira imwe chiratidzo chinobuda waya, imwe pasi waya, uye mbiri waya hita (same ruvara).
Waya yechiratidzo ndiyo inonyanya kukosha pakuongorora kwedu uye kana okisijeni sensor yako yakanganisa unotarisira kuti injini yako ichatambura uye kuratidza zvimwe zviratidzo.
Zviratidzo zveO2 sensor yakakundikana
Zvimwe zvezviratidzo zveyakaipa O2 sensor zvinosanganisira:
- Kupisa cheki injini mwenje pane dashboard,
- Injini yakaoma idling
- Kunhuwa kwakashata kubva muinjini kana pombi yekupedza simba,
- Kusvetuka mota kana simba rekuwedzera,
- Urombo hwemafuta ehupfumi uye
- Urombo hwemotokari mileage, pakati pezvimwe zvinhu.
Kana ukasatsiva sensor yako yeO2 kana ikaita matambudziko, unoisa panjodzi yakawedzera mutengo wekutumira, unogona kupinda muzviuru zvemadhora kana mari yako yemuno.
Unotarisa sei matambudziko neO2 sensor?
Chishandiso chikuru chekugadzirisa matambudziko emagetsi idijitari voltmeter yaunoda.
Maitiro ekuyedza O2 sensor ine multimeter
Seta multimeter yako kune 1 volt renji, ongorora iyo oksijeni sensor siginecha waya nepini, uye mudziye mota kwemaminitsi mashanu. Batanidza iyo yakanaka bvunzo inotungamira yemultimeter kune yekumashure bvunzo lead, gadzika iyo nhema bvunzo inotungamira kune chero simbi iri padyo, uye edza kuverenga kwemultimeter pakati pe2 mV ne100 mV.
Mamwe matanho akawanda anodiwa, saka ticharamba tichitsanangura matanho ese zvakadzama.
- Tora matanho ekudzivirira
Matanho ekuita pano anokubatsira kudzivirira iwo anotevera akaomesesa bvunzo aunofanirwa kuita neO2 sensor yako kuti uwane dambudziko nayo.
Kutanga, iwe unotarisisa nemaziso mawaya kuti uone kana akakuvara kana akasviba.
Kana iwe ukasawana dambudziko navo, iwe ucharamba uchishandisa chishandiso chekuongorora senge OBD scanner kuti uwane kukanganisa macode.
Makodhi ekukanganisa akadai seP0135 neP0136, kana chero imwe kodhi inoratidza dambudziko neokisijeni scanner, zvinoreva kuti haufanirwe kuita mimwe miedzo pairi.
Nekudaro, iyo multimeter bvunzo yakadzama, saka ungangoda kuita mamwe bvunzo.
- Isa multimeter kune 1 volt renji
Oxygen sensors inoshanda mumillivolts, inova chiyero chakaderera chemagetsi.
Kuti uite bvunzo chaiyo yeokisijeni sensor, unofanirwa kuseta yako multimeter kune yakaderera DC voltage renji; 1 volt renji.
Maverengero aunowana kubva pa100 millivolts kusvika pa1000 millivolts, iyo inoenderana ne0.1 kusvika 1 volt zvichiteerana.
- Rear probe O2 sensor chiratidzo waya
Iwe unofanirwa kuyedza iyo O2 sensor nepo waya dzekubatanidza dzakabatana.
Kuisa iyo multimeter probe musocket kwakaoma, saka unofanirwa kuichengetedza nepini.
Ingo pinza pini mune inobuda waya terminal (apo iyo sensor waya inovharira mukati).
- Isa iyo multimeter probe pane yekumashure probe pini
Iye zvino iwe unobatanidza iyo tsvuku (yakanaka) bvunzo inotungamira yemultimeter kune yekumashure bvunzo lead, zviri nani nealligator clip.
Unobva wagaya probe dema (negative) kune chero simbi iri pedyo (senge chasi yemota yako).
- Dziyisa mota yako
Kuti maO2 sensors ashande nemazvo, anofanira kushanda patembiricha inenge 600 degrees Fahrenheit (600°F).
Izvi zvinoreva kuti unofanira kutanga uye kudziya injini yemotokari yako kwemaminitsi mashanu (5) kusvika ku20 kusvika motokari yako yasvika pakupisa uku.
Chenjera kana mota ichipisa zvekuti hauzvipisi.
- Reta zvabuda
Kana uchinge waisa maprobes munzvimbo dzakakodzera, inguva yekutarisa kuverenga kwako kwemultimeter.
Iine sensor inodziya yeokisijeni, iyo DMM inotarisirwa kupa kuverenga kunoshanduka nekukurumidza kubva ku0.1 kusvika ku1 volt kana sensor yakanaka.
Kana kuverenga kukaramba kwakafanana pane imwe kukosha (kazhinji yakakomberedza 450 mV / 0.45 V), iyo sensor yakaipa uye inoda kutsiviwa.
Kuenderera mberi, kuverenga kunogara kwakatsamira (pasi pe 350mV/0.35V) kunoreva kuti mune mafuta mashoma musanganiswa wemafuta zvichienzaniswa neanotora, nepo kuverenga kunogara kwakakwira (pamusoro pe550mV/0.55V) kunoreva kuti pane zvakawanda. yemafuta. musanganiswa wemafuta muinjini uye kuderera kwemhepo.
Kuverengera kwakaderera kunogonawo kukonzerwa nekukanganisa spark plug kana exhaust leak, nepo kuverenga kwakanyanya kunogona kukonzerwa nezvinhu zvakaita se.
- O2 sensor ine yakasununguka pasi yekubatanidza
- EGR vharafu yakanamira yakashama
- Spark plug iri padyo neO2 sensor
- Kusvibiswa kweO2 sensor waya nekuda kwesilicon poisoning
Ikozvino kune mimwe miedzo yekuona kana iyo O2 sensor iri kushanda nemazvo.
Iyi bvunzo inopindura kune yakaonda kana yakakwirira musanganiswa uye inotibatsira kuongorora kana sensor iri kushanda nemazvo.
Lean O2 Sensor Response Test
Sezvambotaurwa, musanganiswa wakaonda kazhinji unokonzeresa iyo okisijeni sensor kuverenga yakaderera voltage.
Kana iyo sensor kuverenga ichiri kuchinjika pakati pe0.1 V uye 1 V, bvisa iyo vacuum hose kubva kune yakanaka crankcase ventilation (PCV).
Iyo multimeter ikozvino inotarisirwa kuburitsa yakaderera kukosha kwe0.2V kusvika 0.3V.
Kana ikasagara ichigara pakati pezviverengero zvakaderera, saka sensor haina kunaka uye inoda kutsiviwa.
Kuedza mhinduro yeO2 sensor kune yakapfuma musanganiswa
Pamuyedzo wemusanganiswa wepamusoro, unoda kusiya hose yevacuum yakabatana nePCV uye wobvisa pombi yepurasitiki ichienda kumusangano wefirita yemhepo panzvimbo.
Vhara buri repaipi pagungano rekuchenesa mweya kuti mweya usabude muinjini.
Kana izvi zvangoitwa, iyo multimeter inotarisirwa kuratidza kukosha kunogara kunosvika 0.8V.
Kana iyo isingaratidzi kukosha kwepamusoro nguva dzose, ipapo sensor haina kunaka uye inoda kutsiviwa.
Iwe unogona kuwedzera kuyedza iyo O2 sensor heater waya ine multimeter.
Kutarisa iyo O2 Sensor Kuburikidza neHeater Waya
Shandura iyo multimeter dial kune ohmmeter kuseta uye unzwe iyo O2 sensor heater waya uye pasi waya materminal.
Ikozvino batanidza kutungamira kwakanaka kweiyo multimeter kune imwe yeheater wire rear sensor pini uye iyo yakaipa inotungamira kune pasi waya rear sensor lead.
Kana iyo oxygen sensor circuit yakanaka, iwe uchawana kuverenga kwegumi kusvika makumi maviri ohms.
Kana kuverenga kwako kusingawire mukati merudzi urwu, iyo O2 sensor haina kukwana uye inoda kutsiviwa.
mhedziso
Kutarisa iyo O2 sensor yekukuvara inzira inosanganisira akati wandei matanho uye nzira dzekuyedza. Iva nechokwadi chekupedza ese kuitira kuti bvunzo yako ipere, kana kubata makanika kana vanyanya kuoma.
Inowanzobvunzwa Mibvunzo
Ingani ohms inofanira kuverenga oksijeni sensor?
An oxygen sensor inotarisirwa kuratidza kuramba pakati pe5 uye 20 ohms, zvichienderana nemuenzaniso. Izvi zvinowanikwa nekutarisa tambo dzekudziya netambo dzepasi kuti dzikuvare.
Ndeipi yakajairika voltage renji kune mazhinji maO2 sensors?
Iyo yakajairika voltage renji yeyakanaka O2 sensor inokurumidza kuchinja kukosha pakati pe100 millivolts uye 1000 millivolts. Ivo vanoshandurwa kuita 0.1 volts uye 1 volts zvichiteerana.
