P0702 Hluav taws xob ua txhaum nyob rau hauv kev sib kis tswj qhov system

P0702 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0702 qhia tias PCM tau kuaj pom muaj teeb meem nrog kev tswj tsis siv neeg kis tau tus mob.

Qhov txhaum cai txhais li cas P0702?

Teeb meem code P0702 qhia tias muaj teeb meem hauv kev tswj tsis siv neeg kis tau tus mob (ATC). Nws qhia tau hais tias lub cav tswj module (PCM) tau txais kev nyeem ntawv tsis raug los ntawm ib qho ntawm cov sensors, solenoid li qub, lossis cov hloov pauv hloov. Qhov no tuaj yeem ua rau kis tau tus mob ua haujlwm tsis raug, tejzaum nws muaj kev hloov pauv hnyav lossis qeeb. Cov lej yuam kev kuj tseem tuaj yeem tshwm sim nrog rau cov lej no. P0700 и P0701.

Tej zaum ua rau

Qee qhov laj thawj rau P0702 teeb meem code:

• Faulty ceev sensors: Kev ua haujlwm tsis zoo ntawm ib qho ntawm cov ntsuas ceev, xws li lub cav sib hloov ceev sensor lossis tsis siv neeg kis tau tus mob tso zis ceev sensor, tuaj yeem ua rau cov cai no tshwm sim.
• Teeb meem nrog solenoid li qub: Kev ua tsis tiav ntawm cov solenoid li qub uas tswj cov iav hloov hauv kev sib kis kuj tuaj yeem ua rau P0702.
• Transmission hloov malfunction: Teeb meem nrog Transmission Range Sensor, uas kuaj pom txoj hauj lwm ntawm lub iav selector qib, kuj yog qhov ua rau qhov yuam kev no.
• Teeb meem nrog kev xaim thiab kev sib txuas: Kev puas tsuaj los yog tawg hauv cov xaim, nrog rau kev sib txuas tsis raug ntawm cov khoom sib txuas ntawm kev tswj hwm, tuaj yeem ua rau P0702 code.
• Teeb meem nrog qhov tsis siv neeg kis tau tus mob tswj module (TCM): Ib qho malfunction nyob rau hauv lub kis tau tus mob tswj module nws tus kheej tuaj yeem ua rau cov ntaub ntawv raug txhais tsis raug thiab ua rau qhov yuam kev no tshwm sim.
• Lwm yam teeb meem kis tau tus mob: Tej zaum yuav muaj lwm yam teeb meem kev sib kis xws li kev ua tsis tiav, cov khoom hnav, thiab lwm yam uas tuaj yeem ua rau P0702 code.

Txhawm rau txiav txim siab qhov ua yuam kev P0702, nws raug nquahu kom kuaj xyuas lub tsheb siv OBD-II scanner thiab kuaj ntxiv.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0702?

Nov yog qee cov tsos mob tshwm sim uas tuaj yeem nrog P0702 teeb meem code:

• Iav hloov teeb meem: Nyuaj lossis qeeb thaum hloov lub zog tuaj yeem yog ib qho ntawm thawj cov tsos mob. Qhov no yuav tshwm sim nws tus kheej raws li hnyav los yog hloov tsis zoo ntawm cov iav.
• Jamming nyob rau hauv ib lub iav: Lub tsheb yuav nyob twj ywm hauv ib lub iav thiab tsis hloov, los yog yuav muaj teeb meem hloov.
• Lub cav ua haujlwm tsis sib xws: Lub cav yuav muaj kev ua haujlwm tsis sib xws thaum lub sijhawm acceleration lossis idling.
• Kos Lub Cav Teeb Illuminates: Thaum kuaj pom P0702, Lub Teeb Lub Cav Ntsuas ntawm koj lub dashboard tuaj yeem tuaj.
• Hom kev tiv thaiv xwm ceev: Qee zaum, lub tsheb yuav nkag mus rau hauv hom xwm txheej ceev kom tsis txhob muaj kev puas tsuaj rau kev sib kis.
• Lwm cov lej yuam kev: Ntxiv nrog rau P0702 chaws, lwm yam kis tau tus mob los yog lub cav tswj kev cuam tshuam cov lej yuam kev kuj tuaj yeem tshwm sim.

Cov tsos mob no tuaj yeem tshwm sim rau qhov sib txawv thiab nyob rau hauv lub tsheb sib txawv. Nws yog ib qho tseem ceeb kom muaj qhov teeb meem kuaj xyuas thiab kho los ntawm tus kws kho tsheb tsim nyog kom sai li sai tau kom tsis txhob muaj kev puas tsuaj ntxiv thiab ua kom muaj kev nyab xeeb ntawm koj lub tsheb.
