Lit check ntawm Lexus

Tom qab kuaj xyuas thiab kho tsheb ntau tshaj kaum xyoo, kuv xav tias cov tsheb Lexus yog cov tsheb zoo tshaj plaws. Lexus kev tawg yog qhov tsawg kawg nkaus, tab sis lawv tshwm sim. Cov no yog cov laj thawj feem ntau cov tswv Lexus tuaj rau kuv los ntawm kuv qhov kev paub dhau los. Koj tuaj yeem nug cov lus nug hauv cov lus, Kuv yuav sim teb.

• roj tank qhov cua yuam kev
• yuam kev P0420/P0430
• vt system
• tsis ua hauj lwm
• oxygen sensors
• P0171
• khob sensor
• catalyst
• lub roj teeb khiav qis

Ua ntej ntawm tag nrho cov, teeb meem nrog lub qhov cua ntawm lub tank roj, cov tsos mob ntawm "kos thiab VSC rau", yuam kev P044X. Yog tias koj daim tshev raug kaw thiab qhov ua yuam kev qhia tias qhov xau hauv lub tank roj "roj vapor leak", thawj zaug xyuas seb lub hau roj tank kaw zoo li cas, kaw lub hau rau ob peb nyem, qhov no yog sau kom raug.

Thaum qhib lub tank lub hau, yuav tsum muaj lub suab nrov nrov, uas ntau tus siv rau kev ua haujlwm tsis zoo, qhov tseeb, qhov tsis hnov ​​​​tsw qhia tau tias ua haujlwm tsis zoo. Tom qab tag nrho, lub tank yog airtight, thiab nyob rau hauv txhua rooj plaub, lub siab nyob rau hauv nws yuav tsis tau atmospheric, nws yog ib txwm ntau los yog tsawg, yog li thaum lub gas tank qhib, lub suab nrov tshwm sim.

Lub cav tswj lub tshuab tswj lub siab no hauv lub tank roj siv lub ntsuas siab, cov roj vapors tau sau rau hauv lub adsorber thiab thaum lub sijhawm ua haujlwm ntawm lub cav, ntawm qhov kev hais kom ua ntawm chav tswj, los ntawm EVAP valve, lawv tau noj rau hauv cov khoom noj thiab hlawv. ua ke nrog cov roj sib tov. Yog tias koj tsis ntseeg qhov kev pabcuam ntawm cov roj tank lub hau, hloov nws, yog tias daim tshev tsis ploj, koj yuav tsum hu rau cov kws kho mob.

Nws tsis tsim nyog ncua kev kho, txij li cov roj xau tsis zoo, raws li koj tus kheej nkag siab. Los ntawm EVAP valve, lawv tau nkag mus rau hauv cov khoom noj khoom haus thiab hlawv nrog rau cov roj sib tov. Yog tias koj tsis ntseeg qhov kev pabcuam ntawm cov roj tank lub hau, hloov nws, yog tias daim tshev tsis ploj, koj yuav tsum hu rau cov kws kho mob. Nws tsis tsim nyog ncua kev kho, txij li cov roj xau tsis zoo, raws li koj tus kheej nkag siab.

Los ntawm EVAP valve, lawv tau nkag mus rau hauv cov khoom noj khoom haus thiab hlawv nrog rau cov roj sib tov. Yog tias koj tsis ntseeg qhov kev pabcuam ntawm cov roj tank lub hau, hloov nws, yog tias daim tshev tsis ploj, koj yuav tsum hu rau cov kws kho mob.

* Hauv kab lus no, kev kuaj mob thiab kho ntawm Lexus RX330 nrog kev ua yuam kev P0442 yog ua raws li piv txwv ntawm kev kuaj mob thiab kho qhov yuam kev P0442 hauv Lexus RX330.

Qhov thib ob feem ntau teeb meem nrog cov laus Lexus RX300/330s yog VVTi system. Cov tsos mob: daim tshev yog nyob rau lossis flashing, P1349 yuam kev, misfiring, cav khob ntawm idle. Feem ntau yog kho los ntawm kev hloov lub VVT valve, tab sis qee zaum qhov kev hloov valve tsis pab, kev kuaj mob ntau dua ntawm VVT system nrog lub cav tester thiab disassembly yog tsim nyog los kho qhov teeb meem.

• piv txwv ntawm VVT kev kuaj mob siv lub cav tester
• misfires, yuam kev P030X, tuaj yeem muaj ntau qhov laj thawj rau misfiring, koj tuaj yeem tshawb xyuas cov ntsaws ntsaws thiab coils koj tus kheej. Daim tshev tuaj yeem nyem thaum nws ua tsis tiav. Cov roj injectors yuav tsum tau kuaj xyuas thiab ntxuav.

* Ntawm no yog kev kuaj mob thiab kho ntawm Lexus RX330 nrog kev ua yuam kev P0300 thiab P0303, daim tshev tau tshwm sim muaj, lub tsheb pib, tsis tsav, thiab lwm yam, Lexus RX330 kos yog flashing

• Ob lub lis piam Lexus P0302
• faulty spark plugs
• ignition kauj test
• Cov pa oxygen sensors qee zaum ua tsis tiav, qhov no tsuas yog hloov cov sensors nrog cov tshiab, yaug cov sensors yuav tsis pab, qhov tsis ua haujlwm ntawm cov pa oxygen sensors feem ntau ua rau muaj roj ntau ntxiv. Cov sensors pem hauv ntej (ua ntej cov catalysts) yog broadband, kuv tsuas yog hloov mus rau qhov qub. Tsis tas li ntawd, kev ua yuam kev P0136 / P0156 tsis tas yuav qhia txog kev ua haujlwm tsis zoo ntawm cov sensors, qee zaum qhov yuam kev no yog tib neeg tsim. Hauv daim vis dis aus no, herd farm tricks ua rau cov pa oxygen sensors tom qab ua tsis tiav.

• yuam kev P0135/P0156
• oxygen sensor
• Kev ua yuam kev P0171 - ntshiv sib tov, nws tshwm sim rau ntau yam laj thawj, ntawm Lexus RX330 yog vim li cas yog qhov hnav ntawm lub damper ncej foob los hloov lub geometry ntawm cov khoom siv manifold, nws yooj yim heev los xyuas, thaum lub cav tsis ua haujlwm, peb Txau cov tshuaj ntxuav carburetor ntawm lub damper ncej, thaum xau los ntawm lub foob, qhov ceev yuav hloov. Kev kho yog hloov valve. Txhawm rau hloov nws, nws yog ib qho tsim nyog yuav tsum tshem tawm cov khoom noj khoom haus, cov kav dej cua txias tsis tso cai rau lub shock absorber tshem tawm. Nws kuj tseem yuav tsim nyog los kuaj xyuas thiab kho cov roj siv hluav taws xob, xyuas cov roj siab, tshawb xyuas lub siab txo valve lossis yaug cov roj injectors. Video roj siab.

• code P0171 lean sib tov
• khob sensors, uas ploj lawm plaub iav yog ntxiv ntawm no rau combustion tswj thiab VSC, feem ntau yog kho los ntawm hloov khob sensors. Txhawm rau hloov, tshem tawm cov khoom noj manifold.
• catalytic converter, yuam kev P0420/P0430, tswj kuj qhib, VSC. Lub catalyst tsis ua haujlwm ntawm txhua lub tshuab, tsis hais hom twg, kev kho kom raug yog hloov nrog ib qho tshiab, tab sis qhov no yog qhov kev xaiv kim heev. Peb tau teeb tsa hluav taws xob hacks uas yeej ua haujlwm ntawm Lexuses.

• Electronic catalytic converter emulator
• dab tsi yog catalyst

Ntawm no Lexus LX470 xyuas kom VSC, TRC nyob rau.

Qhov yuam kev vim malfunction ntawm ob lub catalysts. Txhawm rau tshem tawm qhov yuam kev, nruab emulators ntawm hluav taws xob catalysts p0420.net.

Catalyst emulator hauv khw online catalyst emulator rau Lexus RX330

* Peb kho cov teeb meem catalytic ntawm no RX350 uas kho cov teeb meem catalytic ntawm Lexus RX350

Tau kawg, cov no yog nyob deb ntawm txhua qhov ua tau ntawm kev kub hnyiab thiab VSK, muaj lwm yam tsis raug thiab teeb meem, tab sis lawv tau daws tau zoo tshaj plaws tom qab kuaj xyuas ib txwm, txwv tsis pub ntau lub sijhawm thiab nyiaj txiag yuav raug siv. Cov lus nug tuaj yeem nug hauv cov lus.

Koj tau muab lub tshuab luam ntawv, elm327, koj tuaj yeem kuaj mob dab tsi? RX300 tshuab. Koj puas pom airbag yuam kev?

Tsuas yog ELM327 lub cav thiab tsis siv neeg kis tau tus mob, hauv ncoo xav tau lub tshuab luam ntawv sib txawv. Los yog koj tuaj yeem siv tus kheej kuaj xyuas qhov tsis raug, nws yog qhov nyuaj rau kaw cov pins 4 thiab 13 hauv cov kab mob sib txuas thiab suav cov lej yuam kev los ntawm flashing lub airbag teeb.
