P0167 Oxygen Sensor Heater Circuit Court Malfunction (Sensor 3, Bank 2)

P0167 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0167 qhia tias muaj kev ua haujlwm tsis zoo hauv lub tshuab hluav taws xob oxygen sensor (sensor 3, bank 2).

Qhov txhaum cai txhais li cas P0167?

Teeb meem code P0167 qhia tias muaj teeb meem nrog lub tshuab pa oxygen sensor (sensor 3, bank 2). Cov pa oxygen sensor no ntes cov pa oxygen hauv cov pa tawm thiab pab tswj cov roj / cua sib xyaw hauv lub cav. Thaum ECM (lub cav tswj module) pom tias qhov hluav taws xob ntawm cov pa oxygen sensor 3 lub rhaub hluav taws xob qis dhau lawm, nws qhia tias muaj teeb meem nrog lub rhaub lossis nws lub voj voog.

Tej zaum ua rau

Qee qhov laj thawj rau P0167 teeb meem code:

• Teeb meem nrog oxygen sensor rhaub: Kev ua haujlwm tsis zoo hauv lub tshuab hluav taws xob oxygen sensor nws tus kheej yuav yog qhov ua rau qhov yuam kev no. Qhov no yuav suav nrog luv luv Circuit Court, qhib Circuit Court, lossis tawg cua sov.
• Kev txuas hluav taws xob tsis zoo: Cov neeg tsis zoo los yog oxidized nyob rau hauv lub connector los yog cov hlau txuas nrog lub tshuab pa oxygen sensor tuaj yeem ua rau lub zog tsis txaus lossis hauv av, uas ua rau P0167 code.
• Teeb meem hluav taws xob: Qhib, luv luv, lossis cov kab hluav taws xob puas tuaj yeem cuam tshuam cov hluav taws xob hluav taws xob uas xav tau los ua haujlwm ntawm lub tshuab hluav taws xob oxygen.
• ECM ua haujlwm tsis zoo: Ib qho kev ua haujlwm tsis zoo ntawm lub cav tswj module (ECM) nws tus kheej tuaj yeem ua rau P0167 code yog tias ECM tsis tuaj yeem ua cov teeb liab los ntawm lub tshuab pa oxygen sensor.
• Teeb meem nrog lub catalyst: Qee qhov xwm txheej, teeb meem nrog lub catalytic converter lossis lwm yam khoom siv hluav taws xob yuav ua rau qhov yuam kev no tshwm sim.
• Mechanical puas: Kev puas tsuaj rau cov khoom siv hluav taws xob lossis cov kab hluav taws xob tuaj yeem ua rau muaj teeb meem nrog lub tshuab pa oxygen sensor thiab ua rau P0167.

Txhawm rau txiav txim siab qhov laj thawj kom raug, nws raug nquahu kom ua qhov kev kuaj mob siv cov cuab yeej tsim nyog.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0167?

Cov tsos mob rau teeb meem code P0167 tuaj yeem sib txawv:

• Kev siv roj ntau ntxiv: Kev ua haujlwm tsis zoo ntawm cov pa oxygen sensor yuav ua rau muaj kev sib xyaw ntawm cov roj thiab cua tsis raug, uas yuav ua rau muaj roj ntau ntxiv.
• Lub zog tsis muaj zog: Cov roj tsis zoo / huab cua sib xyaw kuj tuaj yeem ua rau lub cav tsis muaj zog lossis ua haujlwm tsis zoo.
• Tsis ruaj tsis khov: Yog tias cov roj / cua sib tov tsis raug, lub cav yuav tsis ua haujlwm ntxhib, uas yuav ua rau tshee lossis rattling.
• Tshem tawm tsw: Kev sib xyaw ntawm cov roj thiab cua tsis raug tuaj yeem ua rau muaj ntxhiab tsw txawv txav los ntawm qhov tso pa tawm.
• Lub teeb Check Engine los rau: Thaum P0167 tshwm sim, ECM yuav sau cov cai no thiab teeb pom lub teeb pom kev ntawm lub tshuab hluav taws xob ntawm lub ntsuas hluav taws xob kom ceeb toom tus neeg tsav tsheb tias muaj teeb meem nrog lub tshuab pa lossis oxygen sensor.

Cov tsos mob no yuav tshwm sim txawv nyob ntawm tej yam mob thiab hom tsheb.

Yuav ua li cas kuaj tau tus lej txhaum P0167?

Txhawm rau kuaj xyuas DTC P0167, cov kauj ruam hauv qab no raug pom zoo:

1. Xyuas qhov yuam kev code: Siv OBD-II scanner los nyeem P0167 yuam kev code los ntawm lub cav tswj module (ECM) nco.
