I-P0840 Transmission fluid pressure sensor/switch switch A

I-P0840 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

I-Transmission Fluid Pressure Sensor/Switch Circuit "A"

Isho ukuthini ikhodi yephutha P0840?

I-automatic transmission iguqula amandla enjini aphendukayo abe yi-hydraulic pressure ukuze ushintshe amagiya futhi ikuhambise ezansi nomgwaqo. Ikhodi P0840 ingenzeka ngenxa yomehluko phakathi komfutho we-hydraulic odingekayo we-ECU kanye nokucindezela kwangempela, okuvamise ukuhlotshaniswa nenzwa/switch yokudlulisa uketshezi (TFPS). Lena inkinga evamile brand eziningi, kuhlanganise Nissan, Dodge, Chrysler, Honda, Chevrolet, GMC, Toyota nabanye. Izinyathelo zokulungisa zingahluka kuye ngomkhiqizi kanye nohlobo lwenzwa ye-TFPS. Amakhodi ahlobene ahlobene nokucindezela koketshezi lokudlulisela ahlanganisa i-P0841, P0842, P0843, ne-P0844.

Izizathu ezingenzeka

Izizathu zokusetha ikhodi ye-P0840 zifaka:

• Vula isifunda kumjikelezo wesiginali ukuya kunzwa ye-TFPS
• Kufushane ukuya ku-voltage kumjikelezo wesignali yenzwa ye-TFPS
• Kufushane ukuya phansi kumjikelezo wesiginali ye-TFPS
• Inzwa ye-TFPS enephutha
• Inkinga yangaphakathi ngokudlulisa ngesandla
• Ukuntuleka koketshezi lokudlulisela
• Uketshezi/isihlungi esingcolile
• Izintambo ezigugile/izixhumi ezilimele
• Ukuvuza kwe-transmission fluid
• Izinkinga zemojuli yokulawula ukudlulisa (TCM).
• Ukuhluleka kokudlulisela kwangaphakathi
• Izinkinga zomzimba we-valve.

Indlela yokuxilonga ikhodi yephutha P0840?

Ukucacisa ikhodi ye-P0840 kungaba inselele. Uma leli phutha livela, kungase kube nezinkinga ngezintambo, inzwa ye-TFPS, i-TCM, noma izinkinga zokudlulisa zangaphakathi. Kunconywa ukuthi uqale ngokuhlola ama-Technical Service Bulletins (TSBs) futhi wenze ukuhlola okubonakalayo kwesixhumi nezintambo ze-TFPS. Ukuze uthole ukuxilongwa, ungasebenzisa i-digital voltmeter (DVOM) ne-ohmmeter. Uma kutholakala amaphutha, izingxenye ezifanele kufanele zishintshwe futhi amayunithi e-PCM/TCM ahlelelwe imoto yakho. Uma ungabaza, kungcono ukuxhumana nomhloli wezimoto oqeqeshiwe.

Amaphutha okuxilonga

Lapho uxilonga ikhodi ye-P0840, amaphutha ajwayelekile angafaka:

1. Ukuhlolwa okunganele kwamanqamu wesevisi yobuchwepheshe (ama-TSB) ngezinkinga ezaziwayo nezilungiswa ezihlobene nale khodi.
2. Ukuhlolwa okungaphelele noma okungalungile kwezintambo nezixhumi eziholela ku-transmission fluid pressure sensor (TFPS).
3. Ukuchazwa kabi kwemiphumela yokuxilonga, ikakhulukazi mayelana nokucaciswa komkhiqizi wokumelana namandla kagesi.
4. Ukwehluleka ukuhlola izinkinga zokudlulisela kwangaphakathi njengokuvuza, ukuvaleka kwengcindezi noma izinkinga zomzimba wamavalvu.
5. Ukudebeselela ukuhlela kahle noma ukulinganisa i-PCM/TCM ngemva kokushintsha izingxenye.

Njengoba kunikezwe ubunzima bokuxilonga le nkinga, kunconywa ukuthi uxhumane nochwepheshe oqeqeshiwe noma isitolo sokulungisa izimoto ukuze uthole ukuxilongwa okunembile nokuphumelelayo nokulungisa.

Ibucayi kangakanani ikhodi yephutha? P0840?

Ikhodi yenkinga engu-P0840 ibonisa inkinga ohlelweni lokulawula ukudluliswa okuhlobene nenzwa yokucindezela uketshezi oludluliswayo/ukushintsha. Kuya ngembangela ethile nezimo zokusetshenziswa kwemoto, ubunzima bale khodi bungahluka. Eminye yemiphumela engaba khona ingase ihlanganise ukushintshwa kwegiya okungajwayelekile, ukwanda kokusetshenziswa kukaphethiloli, noma ezinye izinkinga zokudlulisela.

Kubalulekile ukunaka izimpawu futhi uqale ukuxilongwa nokulungisa ngokushesha ukuze ugweme ukubhebhetheka kwenkinga kanye nokulimala okungenzeka ekudluliseni. Kunconywa ukuthi uxhumane nochwepheshe oqeqeshiwe ukuze uthole ukuxilongwa okunembile nokuxazulula izinkinga.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0840?

Ukulungiswa okulandelayo kungase kudingeke ukuze kuxazululwe ikhodi ye-P0840:

1. Hlola futhi ushintshe izintambo ezilimele noma eziphukile kusekethe ye-transmission fluid pressure sensor/switch (TFPS).
2. Ukushintsha inzwa/swishi yokudlulisa uketshezi olunephutha.
3. Ukuhlola kanye nokusevisa uketshezi oludlulisayo, okuhlanganisa ukufaka esikhundleni sokuhlunga nokukhipha ukungcola.
4. Thola futhi, uma kunesidingo, shintsha imojula yokulawula ukudlulisa (TCM) noma imojula yokulawula injini (PCM) uma inkinga ihlobene nabo.
5. Hlola futhi ulungise noma yiziphi izinkinga zokudlulisela kwangaphakathi njengokuvuza, ukuvaleka kwengcindezi noma izinkinga zomzimba wamavalvu.

Kunconywa ukuthi uxhumane nochwepheshe oqeqeshiwe noma isitolo sokulungisa izimoto ukuze uthole ukuxilongwa okunembile kanye nomsebenzi wokulungisa ofanele.

P0840 - Ulwazi oluthize lomkhiqizo

Incazelo yekhodi ye-P0840 ingahluka kuye ngokuthi yenziwe kanjani nemodeli yemoto. Nawa amanye ama-decoding emikhiqizo ethile:

1. Ezimotweni zakwa-Ford: I-P0840 ingase ibonise inkinga ngesekhethi yenzwa yokucindezela uketshezi lokudlulisela.
2. Ezimotweni zakwaToyota: I-P0840 ingase ibonise ukwehluleka kumjikelezo wenzwa yokucindezela uketshezi lokudlulisela.
3. Ezimotweni ze-BMW: I-P0840 ingase ibonise inkinga enephutha noma yesignali ngenzwa yokucindezela uketshezi lokudlulisela.
4. Ezimotweni ze-Chevrolet: I-P0840 ingase ibonise inkinga ngesekhethi yokulawula ukucindezela koketshezi.

Uma kubhekwa umehluko phakathi kwezinhlobo namamodeli, kuyanconywa ukuthi ubheke imanuwali yomnikazi wemoto yakho ethile noma imanuwali yokulungisa ukuze uthole ulwazi olunembe kakhudlwana.
