P0071 Ambient air temperature sensor performance

Idatha ye-OBD-II DTC

Ukusebenza kwenzwa yesisindo sokushisa

Kusho ukuthini lokhu?

Le Generic Transmission / Engine DTC imvamisa isebenza kuzo zonke izinjini ezihlome nge-OBDII, kepha ivame kakhulu kwezinye izimoto zakwa-Audi, BMW, Chrysler, Dodge, Ford, Jeep, Mazda, Mitsubishi neVW.

Inzwa yokushisa yomoya ezungezile (AAT) iguqula izinga lokushisa elizungezile libe yisiginali kagesi iye kumodyuli wokulawula amandla we-powertrain (PCM). Lokhu kufakwa kusetshenziselwa ukushintsha ukusebenza kohlelo lokungenisa umoya futhi kubonise izinga lokushisa elingaphandle.

I-PCM ithola lokhu kufaka futhi mhlawumbe amanye amabili; Ukushisa kwe-intake yomoya (i-IAT) kanye ne-engine coolant temperature (ECT) sensor. I-PCM ihlola amandla we-AAT sensor voltage bese uyiqhathanisa nokufundwa kwenzwa ye-IAT / ECT lapho ukuthungela kuqala kuvulwa ngemuva kwesikhathi eside sokupholisa. Le khodi isethwe uma lokhu okufakwayo kwehluka kakhulu. Iphinde ibheke amasiginali wamandla avela kulezi zinzwa ukuthola ukuthi aqinisile yini lapho injini ifudunyezwa ngokuphelele. Le khodi ivamise ukusethwa ngenxa yezinkinga zikagesi, kepha izinkinga zomshini azikwazi ukuxoshwa. Lezi zinkinga zemishini zingafaka ukufakwa okungalungile kwenzwa, ukufakwa kwenzwa okungekho (ukuyishiya ilenga ezintanjeni zocingo), njll.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomkhiqizi, uhlobo lwenzwa ye-AAT, nemibala yocingo.

izimpawu

Izimpawu zingafaka:

• Isibani sesibonakaliso sephutha sivuliwe
• Isipholisi kungenzeka singasebenzi kahle
• Iqoqo lensimbi kungenzeka lingafundi ngokunembile ithempelesha yangaphandle
• Ikhonsoli ephezulu ingahle ingafundi ngokunembile ukushisa kwama-ambient

izizathu

Izimbangela ezingaba khona ze-DTC P0071 zingafaka:

• Vula esifundeni sesiginali kuye inzwa ye-AAT
• Isifunda esifushane kumandla wesifunda kusiginali yesiginali yenzwa ye-AAT
• Isifunda esifushane ngesisindo kumjikelezo wesiginali kunzwa ye-AAT
• Inzwa ye-AAT ayisebenzi
• I-PCM Yehlulekile - Akwenzeki

Izixazululo ezingenzeka

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Bese uthola inzwa ye-AAT emotweni yakho ethile. Le nzwa ivame ukutholakala phambi kwe-radiator ngemuva kwe-grille noma endaweni engaphambili yebhamu. Uma usutholakele, hlola ngokubonakalayo izixhumi nezintambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula izixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwezixhumi. Bona ukuthi zibukeka zishisiwe noma zinombala oluhlaza okhombisa ukugqwala. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka igrisi kagesi lapho amatheminali ethinta khona.

Iphutha elivame kakhulu ukuxhuma, lapho inzwa engalungile ifika endaweni yesibili ngenxa yezimo zemvelo ezimbi.

Lapho uhlola ukuxhumana, ungabheka inzwa ngemitha ye-digital volt ohm (DVOM). Ukuthungela KUVALIWE, nqamula inzwa bese uxhuma i-red (positive) ye-DVOM ukuphela kwesinye esibulalayo ku-sensor kanye nesiginali esimnyama (esingesihle) se-DVOM kwesinye isiphetho. Thola izinga lokushisa lenzwa (yini izinga lokushisa ngaphandle) ngokumelana ngokusho kwetafula. Lokhu ukumelana ne-ohm okufanele kuboniswe yi-DVOM yakho. I-0 ohms noma ukumelana okungapheli (okuvame ukukhonjiswa yizinhlamvu OL) kukhombisa inzwa engalungile.

Uma unethuluzi lokuskena, sula amakhodi ezinkinga zokuxilonga kwimemori bese ubona ukuthi ikhodi iyabuya yini. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Uma ikhodi ye-P0071 ibuya, kuzodingeka sihlole inzwa ye-AAT namasekethe ahambisanayo. Imvamisa kunezintambo ezimbili enzwa ye-AAT. Ukuthungela KUVALIWE, nqamula i-harness kunzwa ye-AAT. Khanyisa ukuthungela. Ngethuluzi lokuskena elifinyelela idatha ye-PCM (kucatshangwa ukuthi liyisimo esithola okokufaka kwe-AAT; imojuli ethola okokufaka kwe-AAT sensor kungaba module yokulawula umoya-moya, imodyuli ye-elekthronikhi, noma enye imodyuli eya emotweni engaphambili engathumela inzwa ye-AAT idatha ngenethiwekhi yebhasi), funda izinga lokushisa noma amandla we-AAT sensor. Kufanele ikhombise ama-volts ama-2 noma enye into ngaphandle kwezinga lokushisa elincane (izinga lokushisa eliphansi kakhulu) ngama-degree. Okulandelayo, cisha ukuthungela, xhuma i-jumper wire kuma-terminals amabili ngaphakathi kwesixhumi se-harness esiya kwinzwa ye-AAT, bese uvula umlilo. Kufanele ifunde ngama-volts ayi-5 noma enye into ngaphandle kwezinga lokushisa elikhona (izinga lokushisa eliphakeme kakhulu) ngama-degree. Uma kungekho 0 volt enzwa noma ungaboni ushintsho, lungisa i-wiring kusuka ku-PCM iye kwinzwa, noma mhlawumbe i-PCM enephutha.

Uma konke ukuhlolwa kwangaphambilini kudlula futhi uqhubeka nokuthola i-P0071, lokhu kuzokhombisa inzwa ye-AAT ehlulekile, yize imodyuli yokulawula ehlulekile ingakhishwa ngaphandle kuze kufakwe inzwa ye-AAT. Uma ungaqiniseki, funa usizo kudokotela oqeqeshiwe wezimoto. Ukufaka kahle, i-PCM kufanele ihlelwe noma ilinganiselwe imoto.
