P0751 Hloov Solenoid Valve "A" Ncua tseg

P0751 – OBD-II Teeb meem Code Technical Description

Teeb meem code P0751 qhia tias qhov hloov pauv solenoid valve "A" tau daig tawm.

Qhov txhaum cai txhais li cas P0751?

Teeb meem code P0751 qhia tias qhov hloov pauv solenoid valve "A" tau daig tawm. Qhov no txhais tau hais tias lub valve tsis txav mus rau txoj haujlwm tsim nyog los ua cov iav hloov, uas tuaj yeem ua rau muaj teeb meem hloov iav hauv kev sib kis tsis siv neeg. Cov tsheb tsis siv neeg kis tau tus mob siv cov solenoid li qub kom txav cov kua dej los ntawm cov kab ke sab hauv thiab tsim lub siab xav tau los hloov lub zog. Yog tias lub khoos phis tawj pom tias qhov sib piv ntawm lub iav tiag tiag tsis sib haum rau qhov yuav tsum tau muaj iav piv, uas yog txiav txim siab los ntawm kev siv lub cav ceev, lub tog raj kheej thiab lwm yam, P0751 yuam kev code yuav tshwm sim.

Tej zaum ua rau

Qee qhov laj thawj rau P0751 teeb meem code:

• Hloov solenoid valve "A" puas lossis ua haujlwm tsis zoo.
• Cov xaim lossis cov khoom sib txuas txuas "A" solenoid valve rau lub cav tswj module (PCM) yuav puas lossis tawg.
• Qhov hluav taws xob tsis raug ntawm solenoid valve "A".
• Teeb meem nrog lub cav tswj module (PCM), uas yuav tsis raug txhais cov teeb liab los ntawm "A" solenoid valve.
• Internal mechanical teeb meem nrog kev sib kis uas tuaj yeem tiv thaiv "A" solenoid valve los ntawm kev txav mus rau txoj haujlwm raug.

Cov no tsuas yog ob peb yam ua tau. Rau kev kuaj mob kom raug, nws raug nquahu kom kuaj xyuas siv lub tshuab kuaj kab mob thiab kuaj xyuas cov hluav taws xob hluav taws xob thiab cov khoom siv tshuab.

Cov tsos mob ntawm tus lej yuam kev yog dab tsi? P0751?

Cov tsos mob rau DTC P0751 yuav suav nrog cov hauv qab no:

• Cov teeb meem hloov pauv: Ib qho kev sib kis tsis siv neeg yuav muaj kev nyuaj lossis qeeb hauv kev hloov lub zog, tshwj xeeb tshaj yog thaum hloov ntawm ib lub iav mus rau lwm qhov.
• Poob Lub Hwj Chim: Lub tsheb yuav muaj kev poob lub zog lossis tsis muaj peev xwm thaum solenoid valve "A" qhib.
• Kev siv roj ntau ntxiv: Yog tias qhov kev sib kis tsis tau ua haujlwm zoo vim yog qhov ua haujlwm tsis zoo ntawm "A" valve, nws yuav ua rau muaj roj ntau ntxiv.
• Ua kom muaj cua sov ntau ntxiv: Kev ua haujlwm tsis raug ntawm "A" valve tuaj yeem ua rau muaj kev sib kis ntawm cov kua dej ntau ntxiv vim qhov hloov pauv tsis zoo.
• Check Engine Light: Lub teeb pom kev teeb pom kev zoo ntawm lub ntsuas hluav taws xob yog ib qho teeb meem ntawm kev hloov pauv solenoid valve "A" thiab tuaj yeem nrog P0751 code hauv PCM nco.

Cov tsos mob no tuaj yeem tshwm sim rau qhov sib txawv nyob ntawm qhov teeb meem tshwj xeeb nrog rau kev hloov pauv.

Yuav ua li cas kuaj tau tus lej txhaum P0751?

Txhawm rau kuaj xyuas DTC P0751, koj tuaj yeem ua raws li cov kauj ruam no:
