P0350 – OBD-II Teeb meem Code Technical Description

Ignition coil thawj/secondary circuit malfunction

Qhov txhaum cai txhais li cas P0350?

Teeb meem code P0350 yog ib qho code rau cov tsheb uas txhawb OBD-II (xws li Hyundai, Toyota, Chevy, Ford, Dodge, Chrysler thiab lwm yam). Nws qhia tau hais tias muaj teeb meem nrog lub hauv paus thiab / los yog theem nrab circuits ntawm lub ignition coils los yog ignition coil los ua ke. Feem ntau ntawm cov tsheb no siv lub ignition system nrog ib tus neeg ignition coils rau txhua lub tog raj kheej. Cov coils no tsim cov nplaim taws kom ignite lub txim taws. Lub ignition system yog saib xyuas thiab tswj los ntawm PCM (engine control module).

Yog tias muaj teeb meem tshwm sim hauv ib qho ntawm cov kab hluav taws xob hluav taws xob, PCM yuav teeb tsa P0350 code, uas yuav ua rau lub cav tsis ua haujlwm zoo. Lub tshuab hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm lub cav, yog li nws yog ib qho tseem ceeb uas yuav tsum tau txheeb xyuas thiab kho cov teeb meem tam sim ntawd kom ntseeg tau tias lub tsheb ua haujlwm tau zoo.

Tej zaum ua rau

P0350 code yog qhib thaum qhov hluav taws xob kaw los ntawm lub tsheb lub khoos phis tawj yog qhov sib txawv ntawm cov chaw tsim khoom lub neej ntawd, tshaj 10%. Qhov teeb meem no tuaj yeem tshwm sim vim muaj qhov tsis zoo los yog puas ntsoog ignition coil, tawg lossis corroded thaiv, txuas txuas tsis raug, lossis tsis raug PCM (lub cav tswj module).

Qhov ua tau ntawm qhov ua tsis tau zoo no suav nrog cov teeb meem nrog lub hauv paus lossis theem nrab ntawm cov kab hluav taws xob hluav taws xob, tsis muaj kev sib cuag hauv cov hluav taws xob sib txuas ntawm cov hluav taws xob hluav taws xob, lossis txawm tias ua haujlwm tsis zoo ntawm PCM nws tus kheej. Cov teeb meem no tuaj yeem ua rau lub tshuab hluav taws xob ua haujlwm tsis zoo thiab yog li ua rau lub cav tsis ua haujlwm zoo.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0350?

P0350 misfire code tuaj yeem yog qhov teeb meem loj thiab nws cov tsos mob suav nrog:

  1. Driveability teeb meem xws li misfires.
  2. Lub cav ua haujlwm tsis raug.
  3. Deterioration hauv roj efficiency.
  4. Muaj peev xwm tshwm sim ntawm lwm yam tsis raug cai xws li P0301, P0302, P0303, P0304 thiab lwm yam.

Cov cai no kuj tseem tuaj yeem ua nrog lub teeb pom kev ntawm lub cav lub teeb, tsis muaj zog, teeb meem pib lub cav, tsis txaus siab, thiab teeb meem nres lub cav. Nws tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cav thiab xav tau kev kuaj mob los kho qhov teeb meem.

Yuav ua li cas kuaj tau tus lej txhaum P0350?

Txhawm rau kuaj xyuas tus lej P0350, ua ntej kos cov kab hluav taws xob ntawm PCM thiab cov hluav taws xob hluav taws xob, nrog rau cov hluav taws xob hluav taws xob lawv tus kheej. Cov cim qhia ntawm cov hluav taws xob hluav taws xob tsis sib txuas tuaj yeem pom los ntawm kev co lawv thiab kuaj xyuas seb lawv txav mus los. Cov cai no feem ntau cuam tshuam nrog cov teeb meem hluav taws xob, yog li xyuas cov xaim thiab cov khoom sib txuas kom zoo. Yog tias cov coils thiab xaim tsis zoo, ces PCM yuav ua yuam kev.

Txhawm rau kuaj xyuas tus lej P0350, koj yuav xav tau lub cuab yeej kuaj mob, lub ntsuas hluav taws xob digital volt / ohm (DVOM), thiab koj lub tsheb cov ntaub ntawv. Thawj kauj ruam yog ua kom pom kev soj ntsuam cov xaim thiab cov khoom sib txuas ntawm cov hluav taws xob hluav taws xob / cov khoom siv. Tshawb xyuas cov khoom sib txuas puas los yog puas los yog corroded thaiv. Sau cov lej khaws cia thiab khov cov ntaub ntawv, tom qab ntawd tshem cov lej thiab coj mus kuaj tsav.

Txhawm rau txiav txim siab lub kauj / chav tsev twg yog qhov tsis raug, ib txoj hauv kev tuaj yeem siv nrog tus pab cuam siv lub nres thiab accelerator kom pom cov kauj twg tsis cuam tshuam rau lub cav ceev. Tom qab no, siv DVOM los xyuas lub roj teeb voltage ntawm lub kauj / thaiv txuas nrog lub ignition ntawm. Yog tias tsis muaj qhov hluav taws xob, xyuas cov fuses thiab relays. Yog tias txhua yam yog OK, xyuas cov circuits rau kev txuas ntxiv thiab tsis kam. Thaum kawg, kos rau hauv av mem tes los ntawm PCM ntawm lub coil connector.

Thov nco ntsoov tias qhov kev hloov kho tshiab yuav tsis daws qhov P0350 code, thiab ceev faj thaum ua haujlwm nrog lub siab siv hluav taws xob nyob ze cov kua hluav taws xob.

Kev kuaj mob yuam kev

Qhov yuam kev thaum kuaj pom tus lej P0350 tuaj yeem suav nrog:

  1. Tsis txaus xyuas ntawm ignition coil thaiv thiab connectors.
  2. Unaccounted rau tawg connectors los yog puas hluav taws xob thaiv.
  3. Tsis ua raws li cov chaw tsim khoom cov lus pom zoo thaum kuaj cov khoom siv hluav taws xob thiab cov khoom siv.
  4. Ua tsis tau zoo xyuas cov mem tes hauv av los ntawm PCM.
  5. Unaccounted rau cov teeb meem nrog rau lwm yam ignition codes uas yuav nrog P0350.

Rau kev kuaj mob kom raug, koj yuav tsum ua tib zoo xyuas tag nrho cov no thiab ua cov kev ntsuam xyuas tsim nyog.

Txoj cai txhaum loj npaum li cas? P0350?

Txawm hais tias lub tsheb uas muaj tus lej P0350 tuaj yeem tsav tsheb mus ntxiv, nws tuaj yeem cuam tshuam loj heev rau nws txoj kev tuav, tshwj xeeb tshaj yog thaum nres thiab nrawm. Txij li qhov kev ua yuam kev no tuaj yeem ua rau lub cav kaw, nws raug nquahu kom ua kev kho kom sai li sai tau txhawm rau xyuas kom muaj kev nyab xeeb ntawm kev tsav tsheb.

Kev kho dab tsi yuav pab tshem tawm cov cai? P0350?

Yog tias ib qho khoom siv cuam tshuam nrog lub tshuab hluav taws xob hluav taws xob (xws li PCM) tau pom tias muaj qhov tsis zoo, nws yog ib qho tseem ceeb uas yuav tau kho lossis hloov lawv raws li qhov yuav tsum tau ua. Yog tias pom muaj teeb meem nrog cov xaim hluav taws xob lossis cov khoom sib txuas, nws yog ib qho tsim nyog yuav tsum rov ua kom txuas ntxiv ntawm PCM thiab cov hluav taws xob tsis zoo los yog hloov cov khoom puas. Tom qab txhua tus neeg kho, nws raug nquahu kom rov kuaj xyuas lub tshuab hluav taws xob kom paub meej tias qhov chaw ntawm qhov tsis ua haujlwm raug tshem tawm.
