P0785 Hloov Sijhawm Solenoid Valve "A" Circuit Court Malfunction

P0785 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0785 qhia tias PCM tau kuaj pom qhov ua yuam kev hauv lub sijhawm ua haujlwm solenoid valve "A" hluav taws xob Circuit Court.

Qhov txhaum cai txhais li cas P0785?

DTC P0785 qhia tau hais tias muaj kev ua txhaum nyob rau hauv lub sijhawm ua haujlwm solenoid valve "A" hluav taws xob Circuit Court. Qhov no txhais tau hais tias lub kis tau tus mob tswj module (TCM) tau kuaj pom muaj teeb meem nrog ib qho ntawm cov li qub uas muaj lub luag haujlwm rau kev hloov cov iav kom raug. Lub kis tau tus mob tswj module, los yog TCM, siv cov ntaub ntawv los ntawm kev hloov lub sij hawm solenoid li qub los tswj cov kev txav ntawm cov kua nruab nrab ntawm circuits thiab hloov lub iav piv, uas yog tsim nyog rau lub tsheb acceleration thiab deceleration, roj efficiency thiab lub cav khiav kom zoo. Yog tias muaj qhov tsis sib xws ntawm qhov kev nyeem ntawv tiag tiag thiab cov txiaj ntsig tau teev tseg hauv cov chaw tsim khoom tshwj xeeb, P0785 code tshwm.

Tej zaum ua rau

Qee qhov laj thawj rau P0785 teeb meem code:

• Solenoid valve tsis ua haujlwm: Lub sijhawm hloov lub sijhawm solenoid valve "A" nws tus kheej yuav puas los yog ua haujlwm tsis zoo, ua rau nws ua haujlwm tsis zoo.
• Kev sib txuas hluav taws xob thiab hluav taws xob: Teeb meem ntawm kev xaim, kev xeb, lossis cov khoom sib txuas hauv cov hluav taws xob hluav taws xob tuaj yeem ua rau cov teeb liab tsis raug ntawm TCM thiab cov solenoid valve.
• Kev txhim kho valve tsis raug lossis hloov kho: Yog tias lub sijhawm hloov pauv "A" tsis tau teeb tsa lossis hloov kho kom raug, qhov no kuj yuav ua rau P0785.
• TCM teeb meem: Lub faulty kis tau tus mob module nws tus kheej tuaj yeem ua rau P0785 vim tias TCM tswj kev ua haujlwm ntawm cov solenoid li qub.
• Teeb meem nrog lwm yam kis tau tus mob: Qee yam khoom sib kis tau zoo, xws li cov ntsuas nrawm lossis lub ntsuas qhov ntsuas, kuj tseem tuaj yeem cuam tshuam nrog solenoid valve "A" ua haujlwm thiab ua rau muaj teeb meem code P0785.

Nyob rau hauv txhua rooj plaub, nws yog ib qho tsim nyog yuav tau ua cov kev kuaj mob ntxiv los txiav txim seb qhov laj thawj ntawm qhov yuam kev no.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0785?

Cov tsos mob rau DTC P0785 yuav suav nrog cov hauv qab no:
