P0073 Ib puag ncig qhov kub thiab txias sensor Circuit Court

DTC P0073 - OBD-II Daim Ntawv Teev Npe

Ambient Cua Kub Sensor Circuit Teeb Siab

Qhov teeb meem code P0073 txhais li cas?

Qhov Kev Xa Mus Los / Cav DTC no feem ntau yog siv rau txhua lub OBDII nruab nrog lub cav, tab sis muaj ntau nyob hauv qee lub tsheb Audi, BMW, Chrysler, Dodge, Ford, Jeep, Mazda, Mitsubishi thiab VW tsheb.

Qhov ntsuas huab cua ib puag ncig (AAT) hloov pauv qhov kub ib puag ncig mus rau lub teeb liab hluav taws xob mus rau lub zog tswj hluav taws xob tswj (PCM). Cov tswv yim no yog siv los hloov kev ua haujlwm ntawm lub tshuab cua txias thiab tso tawm qhov kub thiab txias sab nraum zoov.

PCM tau txais cov tswv yim no thiab tej zaum muaj ob ntxiv; Kev nkag mus rau huab cua kub (IAT) thiab lub cav txias txias (ECT) sensor. PCM tshuaj xyuas AAT qhov ntsuas hluav taws xob thiab sib piv nws rau IAT / ECT sensor nyeem ntawv thaum qhov hluav taws kub tau qhib ua ntej tom qab lub sijhawm txias txias ntev. Cov cai no tau teeb tsa yog tias cov tswv yim sib txawv ntau dhau. Nws tseem txheeb xyuas qhov ntsuas hluav taws xob los ntawm cov ntsuas no txhawm rau txiav txim siab yog tias lawv raug thaum lub cav sov sov. Cov cai no feem ntau tau teeb tsa vim teeb meem hluav taws xob.

Cov teeb meem daws teeb meem yuav txawv nyob ntawm cov chaw tsim khoom, hom AAT sensor, thiab cov xim xaim.

Cov tsos mob

Cov tsos mob feem ntau koj yuav pom yog tias koj lub tshuab cua txias lossis cua sov yuav tsis ua haujlwm zoo. Tej zaum koj yuav pom tias koj yuav tsum tau hloov qhov kub thiab txias ntxiv nyob rau hauv cov kev taw qhia koj xav tau tshaj li qhov koj ib txwm tau ua yav dhau los, los yog koj pom tias nws nyuaj kom ncav cuag qhov koj xav tau. Qhov taw qhia cav check feem ntau tsis teeb, tab sis yog tias koj muaj lwm qhov taw qhia faulty, koj yuav pom qhov ntsuas qhov ntsuas no hloov. Kev nyeem ntawv kub sab nraum zoov kuj yuav tsis raug.

Cov tsos mob tuaj yeem suav nrog:

• Lub teeb qhia tsis raug yog nyob
• Lub tshuab cua txias yuav ua haujlwm tsis raug
• Pawg ntsuas yuav tsis nyeem qhov ntsuas kub sab nraud kom raug
• Sab saum toj console yuav tsis nyeem qhov kub ib puag ncig kom raug

Ua rau P0073 code

Feem ntau qhov teeb meem no yog vim muaj teeb meem nrog lub sensor thiab nws txoj kev txuas rau koj lub PCM (Powertrain Control Module) lossis ECM (Engine Control Module). Qhov no yuav qhia tau tias lub sensor nws tus kheej puas lawm los yog ib feem ntawm cov xaim txuas lub sensor rau PCM / ECM puas. Muaj tsawg zaus, tej zaum yuav muaj teeb meem nrog PCM / ECM, tab sis nyob rau hauv cov ntaub ntawv no, feem ntau koj yuav tau txais lwm yam DTCs dua li P0073 xwb.

Qhov ua tau ntawm DTC P0073 tuaj yeem suav nrog:

• Qhib hauv kab teeb liab mus rau AAT sensor
• Luv Circuit Court ntawm qhov hluav taws xob hauv lub teeb liab Circuit Court ntawm AAT sensor
• Tsis zoo AAT sensor
• Ua tsis tiav PCM - Tsis zoo li

Cov kev daws teeb meem

Qhov pib zoo yog ib txwm tshuaj xyuas cov ntawv xov xwm kev pabcuam (TSB) rau koj lub tsheb tshwj xeeb. Koj qhov teeb meem tuaj yeem yog qhov teeb meem paub nrog cov chaw tsim khoom paub tso tawm kev txhim kho thiab tuaj yeem txuag koj lub sijhawm thiab nyiaj txiag thaum kuaj mob.

Tom qab ntawd pom AAT sensor ntawm koj lub tsheb tshwj xeeb. Qhov ntsuas no feem ntau yog nyob rau pem hauv ntej ntawm lub tshuab hluav taws xob tom qab cov hniav nyiaj hniav kub lossis hauv thaj tsam hauv ntej. Thaum kuaj pom, kuaj pom qhov sib txuas thiab thaiv. Saib rau qhov khawb, khawb, pom cov xov hlau, hlawv cov cim, lossis yas yaj. Txuas cov txuas thiab ua tib zoo tshuaj xyuas cov dav hlau (cov hlau) hauv cov khoom sib txuas. Saib seb lawv puas zoo li hlawv lossis muaj cov xim ntsuab qhia txog kev xeb. Yog tias koj xav tau ntxuav lub davhlau ya nyob twg, siv lub tshuab hluav taws xob tiv tauj thiab txhuam cov yas txhuam. Cia kom qhuav thiab siv roj hluav taws xob qhov twg lub dav hlau kov.

Qhov kev ua txhaum ntau tshaj plaws yog kev sib txuas, nrog lub faulty sensor tuaj rau hauv qhov chaw thib ob vim muaj kev cuam tshuam ib puag ncig.

Thaum txheeb xyuas cov kev sib txuas, koj tuaj yeem tshawb xyuas lub ntsuas hluav taws xob siv digital volt ohm meter (DVOM). Ignition OFF, disconnect tus sensor thiab txuas liab (zoo) DVOM davhlau ya nyob twg rau ib lub davhlau ya nyob twg ntawm lub sensor thiab dub (tsis zoo) DVOM dav hlau mus rau lwm lub davhlau ya nyob twg. Txiav txim siab qhov ntsuas kub ntawm lub ntsuas cua (qhov ntsuas kub sab nraud yog dab tsi) los ntawm qhov tsis kam raws li lub rooj. Nov yog qhov tsis kam tiv thaiv uas koj DVOM yuav tsum tso tawm. Ob qho 0 ohms lossis qhov tsis muaj zog tiv taus (feem ntau qhia los ntawm cov ntawv OL) qhia tias lub ntsuas tsis raug.

Yog tias koj muaj lub cuab yeej luam theej duab, tshem tawm cov teeb meem kuaj mob los ntawm lub cim xeeb thiab pom tias cov cai rov qab los. Yog tias qhov no tsis yog, ces feem ntau yuav muaj teeb meem kev sib txuas.

Yog tias P0073 txoj cai rov qab los, peb yuav tsum tau ntsuas AAT sensor thiab cov khoom siv sib txuas. Feem ntau muaj 2 xov ntawm AAT sensor. Ignition OFF, disconnect lub sam xauv nees ntawm AAT sensor. Hloov ntawm qhov hluav taws kub. Nrog lub cuab yeej luam theej duab nkag mus rau PCM cov ntaub ntawv (piv txwv tias nws yog tus qauv tau txais AAT sensor cov tswv yim; tus qauv tau txais AAT sensor cov tswv yim tuaj yeem yog lub tshuab cua txias tswj qhov qauv, siv hluav taws xob thoob ntiaj teb, lossis qee qhov qauv rau lub tsheb pem hauv ntej uas tuaj yeem xa AAT sensor cov ntaub ntawv hla lub npav npav), nyeem qhov ntsuas kub lossis qhov hluav taws xob ntawm AAT sensor. Nws yuav tsum qhia 5 volts lossis lwm yam uas tsis yog qhov kub ib puag ncig (qhov kub qis heev) hauv qib. Tom ntej no, tua lub qhov hluav taws kub, txuas lub xov hlau txuas mus rau ob lub dav hlau sab hauv lub qhov txuas txuas mus rau AAT sensor, tom qab ntawd qhib qhov hluav taws xob. Nws yuav tsum nyeem txog 0 volts lossis lwm yam uas tsis yog qhov kub ib puag ncig (kub heev) hauv qib. Yog tias tsis muaj 5 volts ntawm lub sensor, lossis koj pom tsis muaj kev hloov pauv, kho qhov thaiv los ntawm PCM mus rau lub sensor, lossis muaj peev xwm ua rau PCM tsis raug.

Yog tias txhua qhov kev xeem dhau los dhau mus thiab koj tseem tau txais P0073, feem ntau nws yuav qhia tau tias AAT ua tsis tau zoo, txawm hais tias qhov ntsuas tsis ua haujlwm tsis tuaj yeem txiav txim siab txog thaum AAT sensor hloov pauv. Yog tias koj tsis paub tseeb, nrhiav kev pab los ntawm tus kws kho tsheb tsim nyog. Txhawm rau teeb tsa kom raug, PCM yuav tsum tau teeb tsa lossis ntsuas rau lub tsheb.

P0073 code loj npaum li cas?

Code P0073 yog ib qho kev kuaj mob hnyav tshaj plaws uas koj tuaj yeem tau txais. Txawm hais tias qhov no tuaj yeem ua rau muaj kev ntxhov siab, tshwj xeeb tshaj yog tias qhov kub thiab txias sab nraud yog qhov nyuaj tshwj xeeb, nws feem ntau tsis hnyav heev. Txawm li cas los xij, koj tseem yuav tsum hu rau tus kws tshaj lij kom pom tias koj tuaj yeem kho qhov teeb meem, raws li feem ntau lub hom phiaj rau cov neeg feem coob yog ua kom koj lub tsheb ua haujlwm zoo.

Kuv puas tuaj yeem tsav tsheb nrog tus lej P0073?

Koj tuaj yeem yuav luag ib txwm tsav nrog P0073 code yog tias tsuas yog tus lej koj lub cav pov tseg. Txawm li cas los xij, nws yuav yog ib lub tswv yim zoo los kuaj xyuas lwm yam teeb meem kev tsav tsheb nrog rau txhua qhov kev kuaj xyuas lub cav tsis zoo. Yog tias tus lej P0073 muaj feem cuam tshuam nrog qhov teeb meem nrog PCM lossis ECM, uas tsis tshua muaj tab sis ua tau, koj yuav tsum tau txais lub tsheb mus rau tus kws tshaj lij sai dua yog tias nws tsuas yog tus lej no xwb. Raws li txoj cai, dhau qhov tsawg kawg yog ib qho kev tshuaj xyuas ntawm koj lub tsheb yog ib feem tseem ceeb ntawm kev ua kom koj tuaj yeem tsav tsheb mus ntxiv yam nyab xeeb.

Nws nyuaj npaum li cas los kuaj tus lej P0073?

Ib zaug ntxiv, kev txheeb xyuas feem ntau yog yooj yim heev; feem ntau koj tuaj yeem qhia tau yog tias ib qho ntawm cov sensors no puas tsuas yog saib nws. Qhov teeb meem tsuas yog tshwm sim thaum koj cov sensors zoo tab sis koj tseem muaj ib qho teeb meem ntawm cov cai no. Hauv qhov no, koj yuav tsum nrhiav kev pab los ntawm ib tus kws tshaj lij, tshwj xeeb tshaj yog tias koj yog tus pib tsis muaj kev paub ntau yam hauv tsheb.
