Yakaderera chiratidzo chiratidzo mune yekudzimisa gasi recirculation sensor C redunhu

Izvi zvinorevei?

Iyi kodhi kodhi yekutakura yakajairika. Inoonekwa seyese kwese kwazvinoshanda kune zvese zvinogadzira uye mamodheru emota (1996 uye nyowani), kunyangwe nhanho dzakananga dzekugadzirisa dzingasiyana zvishoma zvichienderana nemhando yacho.

Kune akasiyana magadzirirwo eexhaust gasi recirculation masisitimu, asi ese anoshanda nenzira imwechete. Iyo Exhaust Gasi Recirculation Valve ivharuvhu inodzorwa nePCM (Powertrain Control Module) inobvumira kuyerwa huwandu hwemagasi emhepo kuti apfuure achidzokera mumacylinders kuti apiswe pamwe chete nemusanganiswa wemhepo/mafuta. Nekuti gasi rinopedza gasi iinert gasi rinobvisa okisijeni, kuvapinza muhumburumbira kunogona kuderedza kupisa kwekupisa, izvo zvinobatsira kuderedza NOx (nitrogen oxide) kubuda.

EGR haidiwe panguva inotonhora kutanga kana kusamira. EGR inosimbiswa pasi pemamwe mamiriro, sekutanga kana kuita idling. EGR system inopihwa pasi pemamwe mamiriro ezvinhu, senge kukamura zvishoma kana kudzikamisa, zvinoenderana neinjini tembiricha uye mutoro, nezvimwewo magasi eEexust anopiwa kune iyo vharuvhu yeEGR kubva pombi yekuzadza, kana vharuvhu yeEGR inogona kuiswa yakanangana muhuwandu hwakawanda . Kana zvichidikanwa, vharuvhu inogoneswa, ichibvumira magasi kuti apfuure mumapombi. Mamwe masisitimu anonongedza gasi rekudzimisa akananga mukati memasirinda, nepo mamwe achingoapinza mukati mezvakawanda zvekudya, kubva kwaanozoiswa mukati memasirinda. nepo vamwe vachingoipinza mukati mezvakadyiwa zvakapetwa, kubva kwainobva yaiswa mukati memasirinda.

Mamwe maEGR masisitimu akareruka, asi mamwe acho akaomesesa. Magetsi anodzorwa emagetsi ekudzora mavharuvhu anodzorwa nekombuta. Iyo harness inobatana kune iyo vharuvhu pachayo uye inodzorwa nePCM painowona ichida. Inogona kunge ina kana mashanu waya. Kazhinji 4 kana 5 zvikonzero, 1V kuvesa wedunhu, 2V rezita redunhu, uye mhinduro redunhu. Mamwe masisitimu anodzorwa nemuchina. Zvakanaka chaizvo. Iyo PCM inodzora iyo yekutsiva solenoid iyo, kana ichigadziriswa, inobvumira iyo vacuum yekufamba kuenda nekuvhura iyo EGR vharuvhu. Mhando iyi yeESV vharuvhu inofanira kunge iine kubatana kwemagetsi kwedunhu remhinduro. Iyo EGR mhinduro loop inobvumira iyo PCM kuona kana iyo EGR vharuvhu pini iri kunyatsofamba mushe.

Kana iyo EGR "C" mhinduro loop ikaona kuti iyo voltage yakadzikira zvisingaite kana kudzika pane yakatarwa magetsi, P044C inogona kumisikidzwa. Tarisa kune yakatarwa gadziriso yekushandisa mota kune iyo nzvimbo ye sensor "C".

Inoenderana chiutsi gasi kudzokorodza sensor "C" mhosva makodhi:

• P044A Kununura Gasi Kuchenesa Sensor C Dunhu
• P044B Kununura Gasi Kuchenesa Sensor "C" Circuit Range / Performance
• P044D Kukosha kwakanyanya kweiyo sensor "C" yeiyo yekudzimisa gasi recirculation system
• P044E Inopindirana / isina kugadzikana EGR sensor dunhu "C"

zviratidzo

Zviratidzo zveP044C kodhi yekunetseka inogona kusanganisira:

• MIL Kuvhenekera (Chisina Kushanda Chiratidziro)

zvikonzero

Zvimwe zvinogona kukonzera kodhi yeP044C zvinosanganisira:

• Ipfupi kune ivhu muEGR maseketi maseketi kana mareferenzi maseketi
• Ipfupi dunhu kune magetsi mune yepasi wedunhu kana maseketi maseketi eiyo mweya wekudzimisa gadziriso sisitimu
• Yakaipa EGR vharafu
• Dambudziko rePCM wiring matambudziko nekuda kwemabraded kana akasununguka matemu

Mhinduro dzinogoneka

Kana iwe uine mukana wekushandisa scan, unogona kuraira iyo EGR vharafu ON. Kana ichiteerera uye mhinduro ichiratidza kuti vharafu iri kufamba nemazvo, dambudziko rinogona kunge riri pakati. Dzimwe nguva, mumamiriro ekunze anotonhora, hunyoro hunogona kuita chando muvhavha, ichiita kuti inamatire. Mushure mekudziya mota, dambudziko rinogona kupera. Carbon kana mamwe marara anogona kunamira muvhavha ichiita kuti inamatire.

Kana iyo gasi rekudzimisa gasi risingapindure kune yekushandisa turu yekuraira, patsanura iyo yekudzimisa gasi kudzokorodza harness yekubatanidza. Chinja kiyi ku "on" chinzvimbo, injini yadzimwa (KOEO). Shandisa voltmeter kutarisa 5 V pane yekuyedza lead yeEGR vharuvhu. Kana pasina mashanu volts, pane chero magetsi zvachose? Kana iwo magetsi ari gumi nemaviri volts, gadzirisa ipfupi kune magetsi pane iyo 5 volt rejereti redunhu. Kana pasina magetsi aripo, batanidza mwenje wekuyedza kune bhatiri voltage uye tarisa iyo 12 V yekunongedzera waya. Gadzirisa kana zvichidikanwa. Kana mwenje wekuyedza usinga vheneke, edza iyo 5 V remberi wedunhu kune yakavhurika. Gadzirisa kana zvichidikanwa.

Kana pasina dambudziko riri pachena uye pasina 5 volt rejisheni, iyo PCM inogona kunge iine hurema, asi mamwe macode anogona kunge aripo. Kana mashanu volts aripo mune revhizheni redunhu, taura 5 volt jumper waya kune iyo EGR chiratidzo wedunhu. Iyo scan chishandiso EGR chinzvimbo chinofanira ikozvino kuverenga zana muzana. Kana ikasabatanidza mwenje wekuyedza kune bhatiri voltage, tarisa iyo dunhu remasaini ekudzimisa gasi kudzokorora. Kana iri, ipapo dunhu remasaini rakapfupiswa kuenda pasi. Gadzirisa kana zvichidikanwa. Kana iyo chiratidzo isingavhenekere, tarisa yakavhurika mudunhu reEGR chiratidzo. Gadzirisa kana zvichidikanwa.

Kana, mushure mekubatanidza iyo 5 V remberi wedunhu kune EGR chiratidzo wedunhu, iyo scan chishandiso inoratidza EGR chinzvimbo chezana muzana, tarisa kusagadzikana kusanzwisisika kumaterminal pane EGR vharuvhu yekubatanidza. Kana iyo wiring iri OK, chinja iyo EGR vharuvhu.
