P0434 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0434 qhia tias lub tsheb lub computer tau kuaj pom tias lub catalytic converter kub kub yog qis dua qhov pib (bank 2).

Qhov txhaum cai txhais li cas P0434?

Teeb meem code P0434 qhia txog kev ua haujlwm tsis zoo ntawm lub catalytic converter cuam tshuam nrog lub txhab nyiaj cav 2. Qhov kev ua yuam kev no tshwm sim thaum lub tsheb lub khoos phis tawj kuaj pom tias qhov kub thiab txias hauv lub catalytic converter qis dua ib theem tau txais. Qhov xwm txheej no yuav ua rau lub catalyst tsis tuaj yeem ua cov khoom tsim kev puas tsuaj uas tsim thaum lub sij hawm sib xyaw roj.

Tej zaum ua rau

Qee qhov laj thawj rau P0434 teeb meem code:

• Catalyst rhaub malfunction: Lub catalytic converter heater tej zaum yuav faulty los yog muaj teeb meem kev txuas hluav taws xob, ua rau lub catalytic converter tsis kub txaus.
• Teeb meem nrog catalyst kub sensor: Yog hais tias lub catalytic converter kub sensor yog faulty los yog tsis muab cov teeb liab raug rau lub Electronic Control Unit (ECU), nws tuaj yeem ua teeb meem code P0434 tshwm.
• Cov roj tsis zoo: Kev siv cov roj tsis zoo lossis impurities nyob rau hauv cov roj yuav ua rau cov combustion tsis txaus, uas yuav ua rau tsis tshua muaj kub hauv cov catalyst.
• Cov pa pa tawm: Cov dej ntws tawm hauv cov pa tawm tuaj yeem ua rau cov catalyst kub poob vim yog dilution ntawm cov pa roj nkag mus rau hauv catalyst.
• Teeb meem nrog cov roj txhaj tshuaj lossis ignition system: Kev ua haujlwm tsis raug ntawm cov roj txhaj tshuaj lossis lub tshuab hluav taws xob yuav ua rau cov roj tsis ua tiav, uas ua rau muaj qhov kub thiab txias.
• Lub cev puas tsuaj rau lub catalyst: Kev puas tsuaj rau lub catalyst, xws li cov kab nrib pleb lossis tawg, tuaj yeem ua rau kev ua haujlwm tsis raug thiab txo qhov kub thiab txias.

Cov no tsuas yog qee qhov laj thawj ua tau rau P0434 code. Txhawm rau txiav txim siab qhov laj thawj kom raug, nws raug nquahu kom ua qhov kev kuaj mob ntawm lub chaw pabcuam kev tso cai lossis tus kws kho tsheb tsim nyog.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0434?

Cov tsos mob thaum muaj DTC P0434 tuaj yeem suav nrog cov hauv qab no:

• Check Engine Light Illuminates (Engine Errors): Ib qho ntawm cov tsos mob pom tseeb tshaj plaws yog Lub Tsheb Tshawb Xyuas Lub Teeb tig rau ntawm koj lub dashboard. Qhov no tej zaum yuav yog thawj lub cim ntawm ib qho teeb meem.
• Deteriorating roj kev lag luam: Tsawg catalyst kub yuav ua rau muaj roj ntau dua li cov catalyst yuav ua haujlwm tsawg dua. Qhov no tej zaum yuav pom tau nyob rau hauv cov roj kev lag luam nyeem ntawm koj lub dashboard.
• Txo kev ua haujlwm: Kev ua haujlwm tsis raug ntawm cov catalyst vim qhov kub thiab txias tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lub cav, uas tuaj yeem pom nws tus kheej hauv cov lus teb tsis zoo lossis tsis muaj zog.
• Kev soj ntsuam tsis tau tiav: Yog tias koj lub tsheb raug kuaj xyuas lossis kuaj cov pa tawm, qhov ntsuas kub qis catalytic converter yuav ua rau nws ua tsis tiav thiab tsis ua tiav qhov kev kuaj xyuas.
• Txo kev ua haujlwm thiab emissions: Qee qhov xwm txheej, yog tias lub catalyst ua haujlwm tsis zoo, koj tuaj yeem pom qhov txo qis hauv lub zog ntawm lub cav lossis kev hloov pauv ntawm cov pa roj carbon monoxide, uas tuaj yeem tshwm sim nws tus kheej hauv qhov nce hauv cov pa phem.

Yog tias koj pom ib qho ntawm cov tsos mob no, nws raug nquahu kom koj hu rau tus kws kho tsheb tsim nyog rau kev kuaj mob thiab kho.

Yuav ua li cas kuaj tau tus lej txhaum P0434?

Txhawm rau kuaj xyuas DTC P0434, peb pom zoo cov kauj ruam hauv qab no:
