I-P042F Exhaust Gas Recirculation Control Stuck Kuvaliwe

Ikhodi Yenkinga ye-OBD-II - P042F - Ishidi Ledatha

I-P042F - Isilawuli sokujikeleza kabusha kwegesi exhaust sibanjiwe

Isho ukuthini i-DTC P042F?

Le yi-Generic Transmission Diagnostic Trouble Code (DTC) esebenza ezimotweni ze-OBD-II. Lokhu kungafaka, kodwa kungagcini lapho, iFord, Chevrolet / GM / Cummins, iDodge / Ram, Isuzu, Pontiac, Toyota, BMW, Mercedes, njll. Ngokuvamile, izinyathelo zokulungisa ngqo zingahluka ngonyaka, uhlobo namamodeli. nokucushwa kokudluliswa.

Uma imoto yakho igcine ikhodi engu-P042F, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole inkinga ngohlelo lokulawula i-valve ye-exhaust gas (EGR).

Endabeni ye-P042F, i-valve iyavela (ukuze i-PCM) ibhajwe endaweni evaliwe. Ukuqokwa A kubhekisa endaweni ethile noma esigabeni sokulawulwa phansi kwe-valve ye-EGR, okuchazwe ngezansi.

Uhlelo lwe-EGR lubhekele ukuvumela injini ukuthi idle uphethiloli ongashiswanga kusuka ohlelweni lokukhipha. I-Exhaust Gas Recirculation (EGR) ibalulekile ukunciphisa amazinga anobungozi we-nitrogen oxide (NOx) avela kuphethiloli nakudizili.

Umgogodla wohlelo lokukhishwa kwegesi yokukhipha i-valve elawulwa ngogesi (i-EGR) evula ukuvumela igesi yokukhipha ibuyele emuva ekufakweni kwenjini. I-PCM isebenzisa okokufaka okuvela kwi-Throttle Position Sensor (TPS), Vehicle Speed ​​Sensor (VSS), ne-Crankshaft Position (CKP) inzwa ukuthola ukuthi izimo zikulungele yini ukuvula / ukuvala i-valve ye-EGR.

Izimoto ezinale khodi zifakwe i-valve yokukhipha igesi yokukhipha igesi. I-valve ye-EGR phansi isebenza ngezigaba ngokuya ngokuvulwa kompintsha, umthwalo wejubane nesivinini semoto.

Kwezinye izinhlobo, indawo ye-EGR valve plunger nayo ibhekwa yi-PCM. Uma indawo oyifunayo ye-EGR valve (ngomyalo we-PCM) yehlukile endaweni eyiyo, ikhodi ye-P042F izogcinwa futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa. Ezinye izimoto zisebenzisa idatha evela kwi-Manifold Air Pressure (MAP) kanye / noma inzwa ye-Differential Pressure Feedback (DPFE) EGR ukuthola ukuthi ngabe i-valve ye-EGR isendaweni efunwayo (noma cha). Izimoto eziningi zizothatha imijikelezo eminingi yokushisa (ukungasebenzi) ngaphambi kokuba i-MIL icishe.

Isithombe se-valve ye-EGR:

Buyini ubunzima bale DTC?

Njengoba indawo evaliwe yegesi yokukhipha igesi ye-exhaust akuyona inkinga enkulu kusuka endaweni yokubuka, ikhodi ye-P042F ingabuyekezwa kusenesikhathi.

Yiziphi ezinye zezimpawu zekhodi ye-P042F?

Izimpawu zekhodi yenkinga ye-P042F EGR zingafaka:

• Cishe ngeke kube khona zimpawu ngale khodi
• Kanciphise ukusebenza kwephethiloli kancane

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P042F zingafaka:

• Iphutha lokukhipha igesi kabusha
• I-EGR solenoid / valve enamaphutha
• Isifunda esivulekile noma esifushane kuzintambo / izixhumi kusekethe yokulawula yohlelo lokukhipha igesi qeda
• Inzwa engaphelele ye-DPFE
• Inzwa yesikhundla se-valve engasebenzi kahle
• Iphutha lokuhlela le-PCM noma le-PCM elingalungile
• I-valve yokulawula ukugeleza kwe-EGR
• Ihhanisi le-solenoid yokulawula ivolumu ye-EGR ivuliwe noma imfushane.
• Isekhethi yokulawula ukugeleza kwe-EGR enephutha
• Inzwa yokushisa ye-EGR kanye nesekhethi yayo

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P042F?

Iskena sokuxilonga, i-digital volt / ohmmeter, nomthombo onokwethenjelwa wolwazi lwemoto kuphakathi kwamathuluzi adingekayo ukuthola ikhodi ye-P042F.

Ukuhlolwa okubonakalayo kwayo yonke i-wiring kanye nezixhumi ezihambisana nohlelo lwe-EGR kuyisibonakaliso esiphelele sokuxilongwa kwekhodi kwe-P042F. Lungisa noma shintsha noma yiziphi izingxenye ezigqamile noma ezishisiwe uma kudingeka.

Bese uxhuma isithwebuli ethekwini lokuxilonga bese ubuyisa wonke amakhodi agciniwe bese uqandisa idatha yozimele. Bhala lokhu njengoba kuzoba wusizo uma i-P042F iyikhodi engena ngezikhathi ezithile. Manje sula amakhodi bese uhlola ukushayela imoto ukuqinisekisa ukuthi ikhodi isuliwe.

Uma ikhodi isuliwe, xhuma isithwebuli bese ubona ukuhamba kwedatha. Bheka indawo oyifunayo ye-EGR (imvamisa ilinganiswa njengephesenti) kanye nendawo yangempela ye-EGR ekhonjisiwe kusibonisi sokugeleza kwedatha. Kufanele zifane ngaphakathi kwama-millisecond ambalwa.

Izinzwa ze-DPFE ne-MAP kufanele zibonise ukuvulwa kanye / noma ukuvalwa kwe-valve ye-EGR (ngokuzithandela). Uma amakhodi wezinzwa we-MAP noma we-DPFE akhona, angahlotshaniswa ne-P042F futhi kufanele aphathwe kanjalo.

Uma indawo ye-EGR oyifunayo yehlukile kunesimo sangempela, landela izincomo zomkhiqizi zokuhlola i-EGR actuator solenoids nge-DVOM. Amaphayiphu we-exhaust gas wehlisa amaphayiphu angasebenzisa ama-solenoids amaningi ukuthonya uhla oluphelele lokusebenza kohlelo lokukhipha igesi qeda.

Uma inzwa ye-DPFE isetshenziswa ohlelweni lokukhipha igesi emotweni yemoto okukhulunywa ngayo, landela izincomo zomkhiqizi zokuyihlola. Amatafula ephini lokuxhuma nemidwebo yokuxhuma imoto etholakala emthonjeni wolwazi lwemoto yakho izosiza ekuhlolweni. Miselela izinzwa ezinamaphutha uma kunesidingo bese uphinde uzame uhlelo.

I-DVOM ingasetshenziselwa ukuhlola amasekethe ngamanye phakathi kwesixhumi se-PCM nesixhumi se-valve ye-EGR. Zonke izilawuli ezixhunyiwe kufanele zinqanyulwe esifundeni ngaphambi kokuhlolwa.

• Ngemuva kokuthi ukulungiswa sekuqediwe, vumela i-PCM ingene kumodi yokulungela ngaphambi kokucabanga ukuthi iphumelele.
