P2122 Throttle Position Sensor D Circuit Low Input

Kev piav qhia ua yuam kev P2122

Qib qis ntawm cov teeb liab nkag mus rau hauv cov saw ntawm lub sensor ntawm txoj hauj lwm ntawm npauj npaim valve / pedal / hloov "D"

P2122 yog Diagnostic Trouble Code (DTC) rau "Throttle Position Sensor/Switch A Circuit Low Input". Qhov no tuaj yeem tshwm sim rau ntau qhov laj thawj thiab nws yog nyob ntawm tus kws kho tsheb txhawm rau kuaj xyuas qhov laj thawj tshwj xeeb ntawm cov cai no tau tshwm sim hauv koj qhov xwm txheej.

Qhov no txhais li cas?

Qhov Diagnostic Trouble Code (DTC) no yog tus lej siv dav, uas txhais tau tias nws siv rau OBD-II cov tsheb uas muaj cuab yeej siv. Txawm hais tias qhov dav dav, cov txheej txheem kho tshwj xeeb yuav txawv nyob ntawm cov khoom lag luam / qauv.

P2122 txhais tau tias lub khoos phis tawj tsheb tau tshawb pom tias TPS (Throttle Position Sensor) tau tshaj tawm qhov hluav taws xob qis heev. Ntawm qee lub tsheb, qhov txwv qis no yog 0.17–0.20 volts (V). Tsab ntawv "D" hais txog ib qho tshwj xeeb Circuit Court, sensor, lossis thaj chaw tshwj xeeb hauv Circuit Court.

Koj puas tau kho thaum lub sijhawm teeb tsa? Yog tias lub teeb liab tsawg dua 17V, PCM teeb tsa txoj cai no. Qhov no tuaj yeem yog qhib lossis luv rau hauv av hauv lub teeb liab. Lossis koj yuav poob qhov 5V siv.

Cov tsos mob ntawm tus lej P2122 tuaj yeem suav nrog:

Cov tsos mob tuaj yeem suav nrog:

• Qhib los yog qis qis
• taug kev
• Loj hlob
• Tsis muaj / me ntsis nrawm dua
• lwm cov tsos mob kuj tseem tuaj yeem tshwm sim

yog vim li cas

Txawm hais tias muaj ntau qhov ua rau P2122 DTC tau teeb tsa, nws yuav yog ib qho ntawm plaub yam tsis raug: lub kaw lus qhov chaw sensor, lub tshuab hluav taws xob tswj lub cev muaj zog, lub tshuab hluav taws xob txoj hauj lwm actuator, lossis pedal txoj hauj lwm sensor. Yog tias tag nrho plaub ntawm cov khoom no ua haujlwm zoo, qhov ua rau tuaj yeem raug puas tsuaj, cov khoom sib txuas, lossis hauv av.

Txoj cai P2122 tuaj yeem txhais tau tias ib lossis ntau qhov xwm txheej hauv qab no tau tshwm sim:

• TPS tsis txuas nrog kev nyab xeeb
• TPS Circuit: luv rau hauv av lossis lwm yam xaim
• Tsis zoo TPS
• Lub computer puas (PCM)

Muaj peev xwm daws tau P2122

Nov yog qee qhov kev pom zoo daws teeb meem thiab kho cov kauj ruam:

• Ua tib zoo txheeb xyuas qhov Throttle Position Sensor (TPS), txuas txuas thiab txuas rau kev so, thiab lwm yam Kho lossis hloov raws li qhov tsim nyog
• Txheeb xyuas qhov hluav taws xob ntawm TPS (saib koj lub tsheb phau ntawv qhia kev pabcuam kom paub ntau ntxiv). Yog tias qhov hluav taws xob qis dhau, qhov no qhia txog teeb meem. Hloov yog tsim nyog.
• Thaum muaj qhov hloov tshiab tsis ntev los no, TPS yuav xav tau kho dua. Ntawm qee lub tsheb, cov lus qhia teeb tsa xav tau TPS kom ua raws lossis hloov kho kom raug, xa mus rau koj phau ntawv qhia rhiav kom paub meej.
• Yog tias tsis muaj cov tsos mob tshwm sim, qhov teeb meem yuav raug ncua, thiab tshem tawm cov cai yuav kho nws ib ntus. Yog tias yog, tom qab ntawd koj yuav tsum tau txheeb xyuas qhov thaiv kom paub tseeb tias nws tsis txhuam nrog txhua yam, tsis yog av, thiab lwm yam. Cov cai yuav rov qab los.

Tus kws kho tsheb kuaj xyuas tus lej P2122 li cas?

Txhawm rau pib kuaj pom qhov ua rau DTC P2122, ua ntej kuaj xyuas nws qhov muaj nyob. Ib tus kws tshaj lij uas tsim nyog tuaj yeem ua qhov no nrog lub cuab yeej tshwj xeeb scanning uas sau cov ntaub ntawv kev ua haujlwm ntawm lub tsheb thiab tshaj tawm cov kev tsis sib xws hauv daim ntawv teeb meem. OB-II. Thaum tus kws kho tsheb ua qhov scan thiab P2122 code tau nkag, yuav tsum tau kuaj ntxiv thiab / lossis kuaj xyuas kom txo qis cov neeg ua txhaum cai.

Cov kauj ruam tom ntej yog feem ntau yog ib qho kev kuaj pom ntawm tag nrho cov xaim thiab cov khoom sib txuas; Yog tias pom cov xov hlau puas lossis cov khoom sib txuas, lawv raug hloov. Tus kws kho tsheb mam li tshem tawm qhov txhaum cai los ntawm lub computer lub cim xeeb thiab siv lub scanner tshwj xeeb dua. Yog tias tus lej P2122 tsis sau npe, qhov teeb meem feem ntau yuav daws tau. Ntawm qhov tod tes, yog tias tus lej sau npe dua, yuav tsum muaj kev kuaj mob ntxiv.

Siv lub digital volt / ohmmeter, tus kws kho tsheb tuaj yeem tshawb xyuas qhov kev nyeem ntawv ntawm qhov hluav taws xob throttle txoj hauj lwm sensor , throttle actuator tswj lub cev muaj zog, throttle txoj hauj lwm actuator thiab pedal txoj hauj lwm sensor. Qhov no yuav pab txiav txim seb ib qho ntawm cov khoom no puas muaj lub luag haujlwm rau qhov tsis tshua muaj hluav taws xob kuaj pom los ntawm lub khoos phis tawj onboard kom cov khoom tsis raug tuaj yeem hloov pauv. Tus kws tshaj lij kuj tuaj yeem kuaj qhov hluav taws xob hla ntawm cov xaim, hauv av, thiab CAN lub tsheb npav los kho lossis hloov cov khoom hnav lossis puas.

Thaum kho tiav lawm, tus kws kho tsheb yuav tshem tawm OBD-II DTC, rov kuaj dua rau qhov tsis txaus ntseeg, thiab tuaj yeem sim tsav lub tsheb kom paub tseeb tias qhov teeb meem tau daws tau zoo.

Feem ntau yuam kev thaum kuaj tus lej P2122

Tom qab sau npe P2122 code, mechanics qee zaum ua yuam kev hauv qab no:

• Tsis muaj peev xwm los daws cov lej txhaum hauv qhov kev txiav txim lawv tshwm sim thaum ntau tus lej tau sau npe
• Tsis tuaj yeem kuaj xyuas tus lej P2122
• Tsis tuaj yeem rov pib dua code P2122 los ntawm lub computer mus ncig tom qab kho

P2122 code loj npaum li cas?

Txawm hais tias qee lub tsheb tsis mus rau hauv qhov "yuav tsis pib" tom qab P2122 DTC nkag mus, qhov no tsis tau txhais hais tias qhov teeb meem uas ua rau nws yuav tsum tsis quav ntsej. Txawm hais tias lub hauv paus ua rau ntawm txoj cai raug kaw yog ib qho kev tiv thaiv tsis zoo, xoob xaim, lossis lwm yam, tsis tuaj yeem kho qhov teeb meem tuaj yeem cuam tshuam rau lwm qhov chaw lossis lub tshuab. Nyob rau lub sijhawm ntev, qhov no tuaj yeem ua rau muaj nqi ntau dua thiab teeb meem nrog kev kho dua li kev kho sai.

Kev kho dab tsi tuaj yeem kho tus lej P2122?

Tom qab P2122 DTC nkag yog suav tias siv tau siv lub cuab yeej scan siab, cov haujlwm hauv qab no yuav tsum tau ua:

• Hloov lossis txav hauv av xaim
• Hloov Cov Hluav Taws Xob thiab / lossis Cov Txuas Txuas hauv CAN Bus Harness lossis Throttle Actuator Tsav
• Hloov lub Throttle Position Sensor, Throttle Actuator Tsav, Throttle Position Actuator lossis Pedal Position Sensor

Cov lus qhia ntxiv los txiav txim siab txog tus lej P2122

Thaum kuaj xyuas tus lej P2122, cov txheej txheem tuaj yeem siv sijhawm li ob peb teev. Qhov no yog vim muaj peev xwm xav tau ntau qhov kev ntsuam xyuas nrog lub tshuab ntsuas hluav taws xob lossis lub ntsuas hluav taws xob, phau ntawv txheeb xyuas thiab kev sim tsav. Nrog rau kev ceev faj txij thaum pib, qhov tshwm sim ntawm lwm yam teeb meem cuam tshuam tau txo qis heev.
