P0879 Transmission fluid pressure sensor / switch D circuit disfunction

Idatha ye-OBD-II DTC

Inzwa Yokucindezela Uketshezi Lokuhambisa / Shintsha Ukungasebenzi Kwesekethe D

Kusho ukuthini lokhu?

Le Generic Transmission / Engine DTC imvamisa isebenza kuzo zonke izinjini ezifakiwe ze-OBD-II, kepha ivame kakhulu kwezinye iDodge / Chrysler / Jeep, General Motors nezimoto zakwaToyota.

Inzwa / iswishi yokucindezela uketshezi lokuhambisa (i-TFPS) imvamisa itholakala inamathiselwe ohlangothini lomzimba we-valve ngaphakathi kokudluliswa, yize kwesinye isikhathi kungatholwa kufihliwe ohlangothini lwecala lokuhambisa / izindlu uqobo.

I-TFPS iguqula ingcindezi yokuhambisa imishini ibe yisiginali kagesi yemodyuli yokulawula amandla we-powertrain (PCM) noma i-module control transmission (TCM). Imvamisa, i-PCM / TCM izokwazisa abanye abalawuli abasebenzisa ibhasi ledatha yemoto.

I-PCM / TCM ithola lesi siginali sevolthi ukucacisa ingcindezi yokusebenza yokudlulisela noma lapho kwenzeka ushintsho lwegiya. Le khodi isethwe uma lokhu okufakwayo kungahambisani namandla kagesi avamile agcinwe kwimemori ye-PCM / TCM. Kungaba futhi ngenxa yezinkinga zangaphakathi zomshini ngaphakathi kokudluliswa.

I-P0879 imvamisa iyinkinga yesekethe kagesi (i-TFPS sensor circuit), yize kushiwo ngaphambili, le khodi ingasethwa futhi ngenxa yezinkinga zemishini (ukuvuza kwangaphakathi, imifantu noma amabhola wokuhlola alahlekile emzimbeni we-valve, ingcindezi / ingcindezi yokusebenza kohlelo oluphansi umugqa, i-valve inamathele emzimbeni we-valve). Lokhu akufanele kunganakwa ngesikhathi sesigaba sokuxazulula inkinga, ikakhulukazi lapho ubhekene nenkinga eqhubekayo.

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

Amakhodi we-Transmission Fluid Pressure Sensor D Amakhodi:

• I-P0875 Transmission fluid pressure sensor / switch "D"
• I-P0876 Transmission Fluid Pressure Sensor / Shintsha "D" Ibanga Lokusebenza Kwesekethe
• I-P0877 Transmission fluid pressure sensor/switch "D" - isekethe iphansi
• P0878 Inzwa yesilinganiso esiphakeme / switch switch fluid fluid "D"

Ukuqina kwekhodi nezimpawu

Ubukhulu buya ngokuthi iphutha lenzeke kusiphi isifunda. Njengoba kungaba yiphutha likagesi noma iphutha elenziwa ngomshini, i-PCM / TCM ingayikhokha ngezinga elithile. Ukungasebenzi kahle kungasho ukuthi i-PCM / TCM iguqula ishift yokudlulisa lapho ilawulwa ngogesi.

Izimpawu zekhodi yenjini engu-P0879 zingafaka:

• Isibani sesibonakaliso sephutha sivuliwe
• Shintsha ikhwalithi yokushintsha
• Imoto iqala ukuhamba ngegiya lesibili noma lesithathu (ukuxhuga kwimodi).

izizathu

Imvamisa isizathu sokufaka le khodi sithi:

• Kuvuleke ngokungapheli emjikelezweni wesiginali kunzwa ye-TFPS
• Okufushane okuphakathi kokungena kumjikelezo wesiginali kunzwa ye-TFPS
• Okufushane okuphakathi komhlaba kuya kumjikelezo wesiginali kunzwa ye-TFPS
• Inzwa ye-TFPS enephutha - mhlawumbe
• Inkinga nge-transmission manual yangaphakathi - kungenzeka
• I-PCM enephutha - akunakwenzeka (idinga ukuhlelwa ngemuva kokushintshwa)

Izinqubo zokuxilonga nokulungisa

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.

Isibonelo esihle salokhu kungaba uma kunamakhodi aziwayo ahlobene namandla asethwe nge-P0879, noma uma kusethwe isethi engaphezu kweyodwa yamakhodi we-pressure sensor / switch. Uma kunjalo, qala ukuxilonga kuqala nge-DTC ehlobene namandla noma thola amakhodi amaningi kuqala, ngoba lokhu kungaba imbangela yekhodi ye-P0879.

Bese uthola inzwa / switch yeTransmission Fluid Pressure (TFPS) emotweni yakho. I-TFPS ivame ukutholakala inamathiselwe ohlangothini lomzimba we-valve ngaphakathi kokudluliswa, yize kwesinye isikhathi kungatholwa kufihliwe ohlangothini lwecala lokuhambisa / izindlu uqobo. Uma usutholakele, bheka ngokubonakalayo isixhumi nentambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula isixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwesixhumi. Bheka ukuthi zibukeka zishisiwe yini noma zine-tinge eluhlaza ekhombisa ukugqwala, ikakhulukazi uma zinamathiselwe ngaphandle kwendlu yokudlulisela. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka igrisi kagesi lapho amatheminali ethinta khona.

Uma unethuluzi lokuskena, sula ama-DTCs kwimemori bese ubona ukuthi iyabuya yini i-P0879. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Le yindawo evame ukukhathazeka kule khodi, njengoba ukuxhumana kwangaphandle kunenkinga yokugqwala kakhulu.

Uma ikhodi ye-P0879 ibuya, kuzodingeka sihlole inzwa ye-TFPS namasekethe ahambisanayo. Uma ukhiye ucishiwe, nqamula isixhumi sikagesi enzwa ye-TFPS. Xhuma ukuhola okumnyama kusuka ku-voltmeter yedijithali (i-DVOM) emhlabathini noma ekugcineni kwesithenjwa esiphansi kusixhumi se-TFPS sensor harness. Xhuma ukuhola okubomvu kusuka ku-DVM kuye esigungwini sesiginali kusixhumi se-TFPS sensor harness. Vula injini, icime. Bheka imininingwane yomkhiqizi; i-voltmeter kufanele ifunde ama-volts ayi-12 noma ama-volts ama-5. Hlanganisa ukuxhumana ukuze ubone ukuthi kushintshile yini. Uma i-voltage ingalungile, lungisa ugesi noma ucingo lwaphansi noma ufake i-PCM / TCM.

Uma isivivinyo sangaphambilini siphumelele, xhuma ukuhola okukodwa kwe-ohmmeter kwisinali yesiginali esenzweni se-TFPS kanti okunye kuholele emhlabathini noma esigungwini esiphansi senkomba esenzweni. Hlola ukucaciswa komkhiqizi ukumelana kwenzwa ukuze uvivinye ngokunembile ukumelana nengcindezi lapho kungekho ingcindezi esetshenziswayo kuyo. Nyakazisa isixhumi kunzwa yokushintsha ingcindezi yokuhambisa uketshezi ngenkathi ubheka ukumelana. Uma ukufundwa kwe-ohmmeter kungadluli, shintsha i-TFPS.

Uma zonke izivivinyo zangaphambilini ziphasile futhi uqhubeka nokuthola i-P0879, kungenzeka ikhombise inzwa ye-TFPS ehlulekile, yize i-PCM / TCM ehlulekile nokwehluleka kokuxhumana kwangaphakathi kungakhishwa ngaphandle kuze kufakwe inzwa ye-TFPS. Uma ungaqiniseki, funa usizo kudokotela oqeqeshiwe wezimoto. Ukufaka kahle, i-PCM / TCM kufanele ihlelwe noma ilinganiselwe imoto.
